Most enzymes can be covalently attached to antibodies using
heterobifunctional crosslinking reagents such as SPDP or SMBP, utilizing
disulphide or thioether bonds. Almost all of these reagents can be
obtained from Pierce. We have used these for antibody-antibody
conjugates as well as antibody-antigen or antibody-enzyme linkages. The
trick is always to minimally substitute the enzyme and antibody to
provide maximum dimeric conjugates without disrupting the enzyme or
antibody activity. I just published a chapter on such techniques. Send
me your (street) address and I'll mail you a photocopy. Sorry text
