I need a protocol to this aim, many years ago I saw a very easy protocol to expand lymphocytes from PBMC using a Flu peptide, but now I have not access to this protocol. If someone has information I would appreciate it.
Here in the lab we use a rapid expansion protocol to generate both CD4+ and CD8+ T-cells from PBMCs, using irradiated feeder cells. Let me know if you want more information about this.
