ChemiSCREEN™ Membrane Preparation Recombinant Human CB2 Cannabinoid Receptor by Merck
EMD Millipore's CB2 membrane preparations are crude membrane preparations made from stable recombinant cell lines with a high-level of GPCR surface expression; thus, they are ideal HTS tools for screening for agonists and antagonists of CB2. The membrane preparations exhibit a Kd of 2.7 nM for [3H]-CP55,940. With 5 μg/well CB2 Membrane Prep and 2.5 nM [3H]-CP55,940, greater than 10-fold signal-to-background ratio is obtained.
