Would you consider purchasing from other suppliers if you knew their products worked?
Selling factor is availability of antibodies for rare, low expessed proteins.
Priority given to suppliers that have catologs including antibodies from immunogens
that are 1. biochemically isolated native proteins (this is rare), 2. full-length recombinant protein, 3. C- and N- termini peptides (at least 1 available). Listing AA sequence of immunogen is great (Abnova does this).
Preference also given to those that list mono and polyclonal antibodies and ship them Ig purified in simple storage buffer (no BSA, little to no glycerol) since I usually need to conjugate the primary antibodies myself.
Quality ratings are great as well as recommendations for applications, cross reactivity info (from companies R&D or user/customer feedback)--Abcam displays this a lot.
I am currently trying different sources for a particular antibody that was discontinued, so I'll give your search engine a try.
