Immunoprecip gurus?

[Stephen Snowdy]

Ok, let's say protein A binds to protein B which binds to protein C.  If
I pull down with an antibody to protein C (from cell lysates), should I
expect to be able to pull down protein A with it and probe for protein A
on a Western, or is it too much to hope for that everthing will stay
together during the IP?  I'm sure it depends on dissociation contants,
but generally speaking...

Are magnetic beads more effiecient than Protein A Sepharose beads?
