Hello, I was wondering if anyone has a protocall for attaching protein (IgG's) to carboxylated microspheres. If so, I would be gratefull if you could forward a copy to me. I would also appreciate any vendors of the microspheres. Thanks in advance. Chris Barry LLNL 7000 East Ave. L-452 Livermore, CA 94550 chbarry at mackiller.llnl.gov
