Hallo everybody,
I have a home-made anti-peptide antibody which detects the target
protein under non-reducing but not under reducing (beta-mercapto)
conditions. Do you know why? I thought the contrary could be the
case.Thanks
Mauro

Obviously, you are unfolding the antibody and thus disrupting the
recognition surface. This is very common. Now you know that your antibody
has a surface, rather than a linear sequence, that recognizes your peptide.
BME reduces disulfide bonds that in your case contribute to correct folding
of the Ab.
