CD64 Protein, Human (HEK293, His)
Based on 2 publication(s) in Google Scholar
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 (HEK293, His) is the recombinant human-derived CD64 protein, expressed by HEK293 , with C-6*His labeled tag.

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
Immobilized Recombinant Human IgG1 Fc at 2 μg/mL (100 μL/well) can bind CD64 Protein, Human (HEK293, His). The ED50 for this effect is 20.0-30.0 ng/mL.

Product Properties
Lyophilized powder
Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
