I'm a gradstudent dealing with immunopurification of proteins, and I have a question for this newsgroup: Has anyone tried to couple chicken IgYs extracted from eggyolks to Affi-Gel Hz (Biorad)? All comments, suggestions, pros and cons are highly appreciated. Thanks for your help! Elena Hilario Dept. Mol. Cell Biology Univ. Connecticut, Storrs CT 06269-3044
