If you make the purchasing call I'd love your thought on antibody suppliers (Santa Cruz, Abcam, Sigma, whoever ...). Particularly I'd be interested to know why you would use one of these bigger middle-men suppliers over the smaller producers. I'm guessing convenience comes in to play but do you shop around on price?
A lot of the antibodies from the bigger vendors are relabelled anyway, but does it matter if you can't tell the original source?
A few questions crammed in there, but any thoughts most welcome.
