I've been using Coomassie Blue staining to get a rough idea of the
concentration of normal rabbit serum. When I do this, I notice that the
bands corresponding to the heavy chains stain significantly more intensely
than the light chain bands... should these be the rough the same intesity
since one IgG contains 2 heavy chains and two light chains??
I'm trying to match the concentration of this normal rabbit serum to a
known amount of immune rabbit serum so that I can perform an
immunoprecipitation with equivalent amounts of IgG's... which bands should
I try to match in intensity (between my immune serum and my non-immune
serum), the heavy chains of each, or the light chains??
