Human Fc gamma RI / CD64 Protein, His Tag (SPR & BLI & MALS verified)

Human Fc gamma RI / CD64 Protein, His Tag (SPR & BLI & MALS verified)

• Background: Receptors that recognize the Fc portion of IgG are divided into three groups designated Fc gamma RI, RII, and RIII, also known respectively as CD64, CD32, and CD16. Fc gamma RI binds IgG with high affinity and functions during early immune responses. Fc gamma RII and RIII are low affinity receptors that recognize IgG as aggregates surrounding multivalent antigens during late immune responses. High affinity immunoglobulin gamma Fc receptor I is also known as FCGR1A, FCG1, FCGR1, CD64 and IGFR1, is a type of integral membrane glycoprotein that binds monomeric IgG-type antibodies with high affinity, which belongs to the immunoglobulin superfamily or FCGR1 family. FCGR1A / CD64 contains 3 Ig-like C2-type (immunoglobulin-like) domains. CD64 is constitutively found on only macrophages and monocytes, but treatment of polymorphonuclear leukocytes with cytokines like IFNγ and G-CSF can induce CD64 expression on these cells.
• Description: Human CD64, His Tag (FCA-H52H1) is expressed from human 293 cells (HEK293). It contains AA Gln 16 - Leu 281 (Accession # P12314-1).
• Specifications: This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 31.8 kDa. The protein migrates as 45-60 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
