Dear Ann
It is possible that the cross linking of proteins from formldehyde caused
negativity, how long was it fixed, I will bet it was longer than the B5, also
did you use same protocol on each tissue, stronger digestion or retrieval may
unmask the EBV in the formalin fixed tissue. Have experienced this as well as
the opposite, steaming too long caused false positivity.
