Why does antibody titer rise after infection? Is ahigh antibody titer indicative of an ongoing infection?Explain

How different are theactions of antibodies againstbacteria and against virus?Why is the cellular immuneresponse activated in case ofchronic viral infection?

How can the anamnestic response be explained in immunologic terms?

1) SDS PAGE gels can be probed with NBT/BCIP to perform an immunoblot true/ false 2) the direction of migration of protiens through a matrix is due to most proteins in natur having a net negative charge  true/false 3)  PBST  is a buffer that is used for blocking the membrane during immunoblotting. true/false 4) the buffer used during for transferring proteins to nitrocellulose methanol. true/false 7) The size of the pores of a polyacrylamide gel dcreases as concentrations of polyacrylamide increases. True or false 10) The secondary antibody used in laboratory for western blotting is conjugated to which enzyme  A) Alkaline decarboxylase B) GAPDH C) Alkaline Phosphatase D) Horseeradish peroxide 13) In protien electrophroresis, what reagent present in the sample buffer is used to eliminate difference in the charge densities of protein A) SDS B) 2- mercaptoethanol C) Tris-HCL pH6.8 D) Tris- HCL PH 8.8
