Is is easy to do ELISA on inclusion bodies? Wound't it be difficult to
bind the denaturated protein we get from the inclusion bodies to the
well? All the ELISA I've performed have been based upon the fact that
you bind the protein of interest to the well via an antibody that
recognizes the protein based on it's folding, a folding a denaturated
protein probably lacks.
Kind regards,
