How can we convert TMB of ELISA for western blot by converting soluble TMB product of ELISA into insoluble with addition of 0.05% sodium nitroprusside? Can I use ELISA TMB substrate for Western blot?
Usually I am doing PCR with 0.5 ul of Taq polymerase (abm) per reaction. Since I wanted to increase the sensitivity of target amplification, I tried PCR with 1.0 ul of Taq. It gave some bands in...
