The CD64 protein is a high-affinity receptor for the immunoglobulin gamma Fc region and plays a key role in innate and adaptive immune responses. It prevents FCGR1A degradation by interacting with FCERG1 and FLNA to form a functional signaling complex. CD64 Protein, Cynomolgus (Biotinylated, HEK293, His-Avi) is the recombinant cynomolgus-derived CD64 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CD64 Protein, Cynomolgus (Biotinylated, HEK293, His-Avi) is 278 a.a., with molecular weight of 40-50 kDa.
