I am wanting to producing Fab from a Mab with immoblized papain(SIGMA
product). But MS result shows
that papain overdigested Mab, and 5 peaks(1 big and 4 little)appeared. I
used papain as 1:10. Could you give me any suggestion about digestion of
Ab by papain and how to control papain action?
Thank you very much for your help. My email address:
