Detection of CRTH‑2 in Human Blood Lymphocytes by Flow Cytometry. Human peripheral blood lymphocytes were stained with Mouse Anti-Human IL‑3 R alpha /CD123 PerCP‑conjugated Monoclonal Antibody (Catalog # FAB301C) and either (A) Mouse Anti-Human CRTH‑2 Alexa Fluor® 488‑conjugated Monoclonal Antibody (Catalog # FAB33381G) or (B) Mouse IgG2A Alexa Fluor 488 Isotype Control (Catalog # IC003G).

CRTH-2, also known as GPR44, is a 7TM G protein-coupled receptor that is
expressed by activated Th2 cells and eosinophils. CRTH-2 binds
Prostaglandin D2 and induces chemotaxis of these cells in allergic and
inflammatory immune responses. Human and mouse CRTH-2 share 78% amino
acid sequence identity.
