We fix the frozen oral, skin or renal sections in EM Grade cold Acetone for
30 minutes, PBS for 30 min and then incubate with titrated antibodies
(according to manufactured are titrated): IgG, IgM, IgA, C3, C1q, C4d(C4d is
time consuming, costly and requires 4 steps=2hrs), CMV, Polymiovirus
(requires 2 steps = 2 hrs), Kappa, Lambda, and Fibrinogen for 1 hour.
