Does anyone know a supplier or manufacturer of recombinant human p450s? I have an grant proposal that may rely on a a reliable source of human p450s. Specifically, I need purified enzymes, and most likely 0.5-2 g of each isoform of interest (mainly CYP 3A4/5 CYP2D6, and CYP1A2).
Microsomes won't work for the this particular application. Sigma has some, but it's about $1/µg, which is way too expensive for way too little.
I would also be open to p450 expression systems and/or purification kits or methods.
