hi , i'm doing my experiment with B cells from MD4 mouse. (which has transgenic BCR specific for antigen HEL ) i tried to activate these B cells with VLP expressing HEL antigen on its surface but it doesn't work well and it seems that B cells didn't proliferate well ..after 3 days culture , i checked viability and it was merely over 0.4% .
i read paper saying that VLP works efficiently on B2 cells but not on B1 cells so i wonder ratio of B1 cells and B2 cells in mouse spleen.
+ i also wonder optimal media condition for culturing mouse B cell .
the media i used to culture is RPMI 1640 with 10% FBS , 1% P/S (penicillin & streptomycin) , 1% glutamax
thanks .
