How do you transfect Lipofectamine?

Mix Lipofectamine 2000 gently before use, then dilute the appropriate amount in 250 μl of Opti-MEM I Medium (or other medium without serum). Mix gently and incubate for 5 minutes at room temperature. After 5 minutes incubation, combine the diluted DNA with the diluted Lipofectamine 2000 (total volume is 500 μl).

Can you use Lipofectamine 2000 for siRNA?

invitrogen Lipofectamine 2000 Reagent is a proprietary formulation that facilitates highly efficient delivery of Invitrogen Stealth RNA molecules, short interfering RNA (siRNA) or plasmid DNA to mammalian cells for RNAi analysis (1, 2).

Is Lipofectamine toxic to cells?

Although Lipofectin showed the lowest toxicity to HepG2 cells (89.54% viability), it displayed the lowest transfection efficacy too (8.29%). Generally, HepG2 cells displayed resistance to the toxicity of majority of the reagents tested, with Lipofectamine 3000 (70.59 % viability), being the most toxic reagent.

How long can I take Lipofectamine?

Depending on the construct used, transiently expressed transgene can generally be detected for 1 to 7 days, but transiently transfected cells are typically harvested 24 to 96 hours post-transfection.

How do you take Lipofectamine 2000?

Nucleic acid-Lipofectamine 2000 complexes can be added directly to cells in culture medium, in the presence or absence of serum. It is not necessary to remove complexes or change/add medium after transfection, but complexes may be removed after 4-6 hours.

How do you transfect cells with siRNA?

9 Tips for Optimal siRNA Transfection

  1. Use the most appropriate siRNA concentration.
  2. Prepare a suitable siRNA stock solution.
  3. Transfect healthy cells.
  4. Check serum quality.
  5. Know the target gene in and out.
  6. Always use positive and negative controls.
  7. Follow up the transfection reagent protocol.

How does Lipofectamine increase transfection efficiency?

You do not even need to change the media after transfection. I use 2.5ul of Lipofectamine 3000 for each 1ug of plasmid each in 50ul optiMEM incubate for 20 min at room temp, then add to 1^6 of HEK293cells that plated in DMEM supplemented with 10% FCS, 48 hours later collect media. I got 90% efficiency.

How do plasmids transfect cells?

By performing a process of DNA transfection, a plasmid which contains a gene of interest is efficiently delivered to the cells of interest. Upon delivery to the cells plasmid DNA reaches the nucleus during cell division, the gene of interest is transcribed and its transient expression is achieved.

What is the transfection protocol for Lipofectamine rnaimax?

Lipofectamine® RNAiMAX Reagent Protocol 2013-2-Typical RNAiMAX Transfection Procedure Transfect cells according to the following table. The transfection is designed for one RNA amount combined with one amount of Lipofectamine® RNAiMAX. The prepared

How does Lipofectamine work as a transfection reagent?

Simply mix Lipofectamine® RNAiMAX Transfection Reagent with siRNA, add to your cells, incubate, and measure gene knockdown. The simplicity and speed combined with high transfection efficiency make Lipofectamine® RNAiMAX Transfection Reagent ideal for high-throughput siRNA transfections.

Which is the best siRNA for Lipofectamine knockdown?

The Lipofectamine RNAiMAX protocol recommends using 10 nM siRNA as a starting point to maximize knockdown levels. Figure 1. Superior knockdown with Lipofectamine RNAiMAX Transfection Reagent compared to competing siRNA transfection reagents.

How is Lipofectamine used for gene silencing?

For gene silencing, Lipofectamine® RNAiMAX Transfection Reagent’s high-efficiency transfections lead to the high levels of gene knockdown needed to achieve convincing results. Simply mix Lipofectamine® RNAiMAX Transfection Reagent with siRNA, add to your cells, incubate, and measure gene knockdown.
