I accidentally stored Cellfectin II Reagent (Cat. No. 10362100) at -20 degrees C. Can I still use it? Product FAQ

Answer

We can't guarantee performance because freezing compromises activity of the reagent.

May I filter-sterilize the siRNA/lipid complex before injection into the mouse? Product FAQ

Answer

Yes, you may do so by using a 0.22 µm pore size for filter-sterilization. However, our best recommendation is to always keep your procedure sterile from start-to-finish.

With Lipofectamine Stem Transfection Reagent, how can I improve the transfection efficiency in my stem cells? Product FAQ

Answer

To obtain the highest percent of stem cells transfected with Lipofectamine Stem Transfection Reagent, we highly recommend that you follow cell culture conditions that promote formation of a monolayer versus clumps of cells. If the density of your stem cells is greater than 50% or they are being grown as colonies in other media, more Lipofectamine Stem Transfection Reagent may improve transfection efficiency. For additional details, please refer to the Lipofectamine Stem Transfection Reagent protocol pertinent to your cell type and media on the product page (https://www.thermofisher.com/order/catalog/product/STEM00008?ICID=search-product), under Documents, Product Literature.

How does the use of Lipofectamine 2000 reagent improve transfection over the other lipid reagents? Product FAQ

Answer

It generally yields better transfection activity (as measured by protein expression) than all other lipids in a majority of the cell lines tested. It includes a streamlined, simple protocol where the complexes are added directly to cells without changing media. This lends itself to high throughput applications. It works very well in the presence or absence of serum. Examples of cells that show the highest transfection efficiency with Lipofectamine 2000 include 293 F, 293 H, BE(2)C, CHO-K1, CHO-S, COS-1, COS7-L, Human Primary Fibroblasts, Ht-29, HT-1080, MDCK, MRC-5, PC12 and Vero.

For in vivo siRNA delivery, do I need to weigh my mouse to determine dosing, or can I use the standard 200 µL of complexed material for systemic intravenous injection? Product FAQ

Answer

To ensure the best results and minimal toxicity, it is very important to determine the weight of each mouse to provide the correct dose and to maintain uniform dosing of multiple animals. The recommended dose for mice is 1.0 mg/kg (intravenous), depending on the potency of your siRNA.

Do you have any suggestions for genes to use for normalizing my qPCR analysis after in vivo siRNA delivery? Product FAQ

Answer

We recommend using housekeeping genes for normalization. The expression levels of housekeeping genes can vary depending on the experimental conditions and/or tissue type. We have obtained the most consistent results by normalizing target gene expression to HMBS and GAPDH. Consider using the TaqMan Array Mouse or Rat Endogenous Control Panels to identify appropriate controls regardless of cell, tissue, or organ combined with treatment type. To look for endogenous controls in other species, please visit our TaqMan Endogenous Control Assays here https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/real-time-pcr-assays/taqman-gene-expression/taqman-endogenous-controls.html

For additional information on housekeeping genes, please visit our qPCR Education webpage: https://www.thermofisher.com/us/en/home/life-science/pcr/real-time-pcr/qpcr-education.html
