GPCR Preparation as Immunogen

Based on our world-leading Magic™ membrane protein platform, scientists from Creative Biolabs now provide professional GPCR immunogen preparation service.

G protein-coupled receptors (GPCRs) constitute the largest membrane receptor family with over 800 members. Given their high relevance to diverse diseases, GPCRs act as excellent therapeutic targets of over 40% modern drugs, especially therapeutic antibodies. However, one of the major difficulties for anti-GPCR antibody development lies in the appropriate preparation immunogen, due to their complicated structure and low abundance. After years of devotion, scientists in Creative Biolabs have established a full range of methodologies for obtaining native, functional GPCR proteins that can serve as great immunogens in vivo. We provide flexible options, e.g. detergent micelles, nanodiscs, liposomes, polymers, over-expressing cells, lipoparticles, etc. (as listed below), which from you can always find the best fit for your particular target.
