ChemiScreen™ VPAC1 Membrane Preparation
MerckChemicon's VPAC1 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of antagonists of VPAC1 interactions with VIP. The membrane preparations exhibit a Kd of 1.2 nM for [125I]-VIP. With 2.5 μg/well VPAC1 Membrane Prep and 0.4 nM [125I]-VIP, a greater than 5-fold signal-to-backg…
