When we used LNP to deliver GFP mRNA to Jurkat cells, the efficiency was as high as 90%. However, when we delivered GFP mRNA to T cells, we failed, with an efficiency of 0.5-0.6%. Could anyone help us? Thanks a lot!
Jurkat cells are usually easily transfected through different protocols whereas T cell transfection is more difficult to achieve. You might want to try changing your lipid mixture composition. If you do not want to try many different combinaisons, Precision Nanosystems sells a LNP transfection kit adapted for T cells.
Thanks for your suggestion. Because we made the LNP composition for the first time for T cells, we are afraid there are some tips that we ignored. For example, we used 1640 medium and human serum to incubate the T cells. Thanks a lot!
