CD64 Protein, Human (Biotinylated, 272a.a, HEK293, His-Avi)

Customer Review

Based on 1 Customer Validation

CD64 protein, a high affinity receptor, mediates IgG effector functions, triggering antibody-dependent cellular cytotoxicity (ADCC). It interacts with IGHG1 and forms a signaling complex with FCERG1, contributing to immune responses. CD64 also interacts with FLNA, EPB41L2, LAT, PPL, HCK, and LYN to prevent degradation of FCGR1A and regulate immune function. CD64 Protein, Human (Biotinylated, 272a.a, HEK293, His-Avi) is the recombinant human-derived CD64 protein, expressed by HEK293 , with C-Avi, C-His labeled tag.

It interacts with IGHG1 and forms a signaling complex with FCERG1, contributing to immune responses. CD64 also interacts with FLNA, EPB41L2, LAT, PPL, HCK, and LYN to prevent degradation of FCGR1A and regulate immune function.

Background

CD64 protein is a high affinity receptor for the Fc region of immunoglobulins gamma. It plays a role in both innate and adaptive immune responses. CD64 mediates IgG effector functions on monocytes, triggering antibody-dependent cellular cytotoxicity (ADCC) against virus-infected cells. It interacts with IGHG1 and forms a functional signaling complex with FCERG1. CD64 also interacts with FLNA, preventing degradation of FCGR1A. Additionally, it interacts with EPB41L2, LAT, PPL, HCK, and LYN, contributing to its diverse functions in immune regulation.

Verified Bioactivity

1.Immobilized Anti-CD20(Ro) Antibody (Rituximab) at 1 μg/mL (100 μL/well) can bind Recombinant Human CD64 / FCGR1A Protein (His & AVI Tag), Biotinylated, the EC50 is 1-3 ng/mL.
2.Biotinylated Human Fc gamma RI, His-Avi Tag captured on CM5 Chip via Anti-His Antibody can bind Trastuzumab with an affinity constant of 5 nM as determined in SPR assay (Biacore T200).
