Product Introduction


In the field of modern biomedical research and biotechnology applications, cell transfection technology is a crucial tool that plays an irreplaceable role in gene function research, drug develop

ment, disease mechanism exploration, and many other aspects. GeticoFect® 2000 Transfection Reagent, as a carefully developed multi-purpose universal transfection reagent, provides researchers with a powerful and reliable transfection solution with its excellent performance and wide applicability.


I. High-Efficiency Transfection Capability in Multiple Scenarios


GeticoFect® 2000 Transfection Reagent demonstrates remarkable applicability in multiple scenarios, providing efficient transfection effects for both adherent and suspension cell lines. Adherent cells, such as common HEK-293 and HeLa cell lines, attach to the surface of culture containers during growth. Transfection of such cells needs to consider the interaction between the reagent and the cell surface, as well as the mechanism of transfection complexes entering the cells. GeticoFect® 2000 Transfection Reagent can effectively bind to the cell membrane of adherent cells, form stable transfection complexes, and then efficiently deliver exogenous nucleic acids into the cells. For suspension cells, such as Jurkat and K562 cell lines, which grow in suspension in the culture medium, transfection is relatively more difficult. Through its unique formula and mechanism of action, GeticoFect® 2000 Transfection Reagent can form a suitable transfection microenvironment around suspension cells, promote nucleic acid uptake, and achieve efficient transfection.


Through a large number of rigorous experimental verifications, GeticoFect® 2000 Reagent has wide application value in the field of gene research. It can be used in gene knockout experiments based on siRNA and shRNA. In gene knockout experiments, siRNA (small interfering RNA) or shRNA (short hairpin RNA) can specifically bind to the mRNA of the target gene, guide the RNA-induced silencing complex (RISC) to cleave it, thereby inhibiting the expression of the target gene. GeticoFect® 2000 Transfection Reagent can efficiently deliver siRNA or shRNA into cells, ensuring that they function in cells to achieve accurate gene knockout effects. At the same time, the reagent can also be used in gene expression research by introducing plasmids or other expression vectors carrying target genes into cells, allowing them to express corresponding proteins in cells, thereby studying gene functions and regulatory mechanisms.


II. Detailed Explanation of Significant Advantages

(I) Excellent Transfection Efficiency and High Recombinant Protein Expression Level


GeticoFect® 2000 Transfection Reagent has shown excellent transfection efficiency in hundreds of cell lines. This is due to its unique chemical composition and optimized formula. Some components in the reagent can form stable complexes with nucleic acids, protect nucleic acids from degradation by intracellular nucleases, and promote the binding and internalization of complexes with cell membranes. On the basis of efficient transfection, it can also achieve a high level of recombinant protein expression. After the exogenous gene is successfully introduced into the cell, the intracellular environment created by GeticoFect® 2000 Transfection Reagent is conducive to the transcription and translation of the gene, enabling a large amount of synthesis and expression of recombinant proteins. This is extremely important for experiments that need to obtain a large amount of recombinant proteins for subsequent research or applications.

In gene silencing applications, the efficient transfection ability of GeticoFect® 2000 Reagent plays an important role. It can efficiently deliver siRNA or shRNA into cells, achieving a high level of gene knockout. By precisely inhibiting the expression of target genes, researchers can conduct in-depth studies on gene functions and related biological processes. In the research of some disease models, gene knockout experiments can determine whether a certain gene is related to the occurrence and development of the disease, providing a theoretical basis for disease diagnosis and treatment. Since GeticoFect® 2000 Reagent can achieve satisfactory gene knockout effects, researchers can obtain accurate and reliable experimental results, promoting the in-depth development of gene research.


V. Convenient Operation Characteristics


GeticoFect® 2000 Transfection Reagent is extremely convenient in operation. It only requires simple preparation: mix the reagent with nucleic acid in a certain proportion, incubate briefly to form transfection complexes, and then directly add them to the cell culture. This simple operation process reduces human errors in the experimental process and improves the repeatability of the experiment. More importantly, it supports a no-medium-change cell transfection system. In traditional transfection experiments, it is often necessary to change the medium after transfection to remove the potential toxicity of the transfection reagent to cells. However, due to its low toxicity and good cell compatibility, GeticoFect® 2000 Transfection Reagent does not require medium change, which not only simplifies the experimental process, saves time and energy but also reduces damage to cells, improving cell survival rate and transfection effect.


1. Q: What are the storage conditions for GeticoFect 2000 Transfection Reagent?

A: GeticoFect 2000 must be stored at 4°C and must not be frozen. Freezing can destroy the integrity and composition of lipid particles, affecting reagent performance. Even if frozen for about a week, it may be risky, so it is recommended to purchase new reagents to ensure functionality. Additionally, the reagent can remain stable at room temperature for several months.


2. Q: If GeticoFect 2000 is accidentally left at room temperature, can it still be used?

A: Yes, it can still be used. All liposome transfection reagents (including GeticoFect 2000) can remain stable at room temperature for several hours, so accidentally leaving it at room temperature once will not significantly affect its performance.


3. Q: The transfection efficiency with GeticoFect 2000 is very low. What might be the reasons and solutions?

A:
  • Possible reasons:
    • Plasmid DNA, siRNA, or transfection reagent is diluted in serum-containing medium, or complexes are formed in the presence of serum.
    • The ratio of DNA to transfection reagent is inappropriate for the cell line.
    • Insufficient amount of plasmid DNA used for dilution or complex formation.
    • Degraded or poor-quality plasmid DNA or siRNA is used in transfection.
    • Inappropriate cell density.
    • Complexes are added to cells in serum-free medium (some cells have reduced uptake capacity under serum-free conditions).
    • Presence of inhibitors in the medium (e.g., antibiotics, EDTA, citrate, phosphate, etc.).
    • Problems with the detection method for measuring efficiency or expression.
    • The promoter-enhancer on the vector is not recognized by the cell type.
    • Cells have changed over time or passage conditions have altered.
    • Improper storage of the transfection reagent.
  • Solutions:
    • Dilute plasmid DNA, siRNA, and transfection reagent in serum-free medium (e.g., Opti-MEM).
    • Optimize the ratio of DNA to GeticoFect 2000 (for most cell lines, a ratio of 1:2 to 1:3 (μg:μL) is recommended; adjust between 1:0.5 to 1:5 if needed).
    • Verify DNA concentration using a spectrophotometer or Quant-it DNA analysis kit and check for degradation.
    • Ensure high-quality plasmid DNA or siRNA (use PureLink HiPure nucleic acid purification kits for plasmid purification).
    • Control cell density (transfection efficiency is often best when cells are >90% confluent, but adjust based on cell type).
    • Use serum-containing growth medium for transfection; test compatibility with serum-free formulations if necessary.
    • Avoid inhibitors (e.g., antibiotics) in the medium used for complex preparation or transfection.
    • Use reporter genes to measure transfection efficiency.
    • Confirm that the vector’s promoter-enhancer is compatible with the target cell type.
    • Maintain consistent cell passage and plating schedules; avoid over-passaging and 复苏 new cells if performance drops.
    • Store GeticoFect 2000 at 4°C as recommended.


4. Q: Why is there cytotoxicity after transfection with GeticoFect 2000?

A:
  • Possible reasons:
    • Inappropriate DNA-to-reagent ratio for the cell line.
    • High endotoxin levels in plasmid DNA preparations.
    • Unsuitable cell density.
    • Complexes are added to cells in serum-free medium.
    • Poor mixing of complexes in the growth medium (leading to local high concentrations).
    • Changes in cell characteristics over time or altered passage conditions.
  • Solutions:
    • Optimize the DNA-to-GeticoFect 2000 ratio (start with 1:2 to 1:3 (μg:μL), adjust between 1:0.5 to 1:5).
    • Use high-quality plasmid DNA (purified with PureLink HiPure kits to reduce endotoxins).
    • Control cell density (confluency >90% often minimizes toxicity for GeticoFect 2000).
    • Use serum-containing medium for transfection; test serum-free compatibility if required.
    • Thoroughly mix complexes with medium after addition to avoid local concentration spikes.
    • Maintain consistent cell passage protocols; avoid over-passaging and 复苏 new cells if toxicity increases.


5. Q: What are the requirements for cells before transfection?

A:
  • Cell state: Use low-passage cells with >90% viability and no contamination.
  • Cell density: Transfection is typically optimal when cells are 80%-90% confluent, though some cell lines may perform better at higher densities with GeticoFect 2000 (optimize based on cell type).
  • Passage control: Avoid excessive passaging (generally <20-30 passages) to prevent phenotypic changes that reduce transfection efficiency.


6. Q: Can antibiotics be used during transfection?

A: It is not recommended. Antibiotics may reduce transfection efficiency and increase cytotoxicity by interacting with GeticoFect 2000. While some studies show no impact in specific cell lines, err on the side of caution: avoid antibiotics during transfection and add them ≥72 hours later for stable transfection selection.


7. Q: How to prepare DNA-GeticoFect 2000 complexes?

A: For each transfection sample:
  1. Dilute DNA and RNAi molecules (if used) in serum-free Opti-MEM I medium; mix gently.
  2. Dilute GeticoFect 2000: Mix the reagent gently before use, then dilute in serum-free Opti-MEM I; incubate at room temperature for 5 minutes.
  3. Combine diluted DNA/RNAi with diluted GeticoFect 2000; mix gently and incubate at room temperature for 20 minutes to form complexes (slight turbidity is normal and does not affect transfection).


8. Q: Is the DNA-to-GeticoFect 2000 ratio the same for all cell lines?

A: No. Optimal ratios vary by cell type. Most cell lines perform well with a 1:2 to 1:3 (μg:μL) ratio, but specific lines may require adjustments between 1:0.5 and 1:5. Always optimize the ratio for your target cell line.


9. Q: Is it necessary to change the medium after transfection?

A: No, medium change is not required. However, replacing medium 4-6 hours post-transfection is acceptable and may benefit sensitive cell types (e.g., neurons) without reducing transfection activity.


10. Q: Can GeticoFect 2000 be used for co-transfection of plasmid DNA and siRNA?

A: Yes. GeticoFect 2000 efficiently delivers both plasmid DNA and siRNA simultaneously. Follow standard transfection guidelines: use serum-free medium for dilution, optimize the total nucleic acid-to-reagent ratio, and control cell density to ensure high efficiency.


11. Q: Why are small granular precipitates observed on cells after adding complexes?

A: Precipitates typically form due to excess EDTA or GeticoFect 2000. Dilute DNA in water (or TE with ≤0.3 mM EDTA) and avoid exceeding recommended reagent concentrations. Precipitates do not necessarily correlate with transfection performance.


12. Q: Bright orange granular background fluorescence is observed when transfecting GFP with GeticoFect 2000. What causes this?

A: This orange fluorescence is associated with lipid-DNA complexes (not GFP) and is common with cationic liposomes like GeticoFect 2000. It varies by reagent but rarely interferes with results. For clearer imaging, try PBS instead of medium. Ensure cells are healthy (lysed or stressed cells may produce autofluorescence that complicates observations).
