Hello,
I have some vials LN2 frozen immune cells from the draining lymph nodes of BCG-vaccinated macaques. I want to know if BCG is in these cells, and since I suspect it will be in very few of them, so I am looking for a way to culture it back out.
I'm having trouble finding a paper where it has been done, but I am assuming someone has cultured BCG or other intracellular bacteria from frozen primary cells before and that a protocol exists. Any help would be appreciated. Thanks!
