Customer Review

Based on 1 Customer Validation

Fc gamma The RIIA/CD32a protein plays a key role as a low-affinity receptor that specifically binds to the Fc region of immunoglobulin gamma. It interacts with IgG to initiate cellular responses against pathogens, which is critical for immune regulation. Fc gamma RIIA/CD32a Protein, Human (H167R, HEK293, His) is the recombinant human-derived Fc gamma RIIA/CD32a protein, expressed by HEK293 , with C-6*His labeled tag and H167R mutation.

Description

Fc gamma The RIIA/CD32a protein plays a key role as a low-affinity receptor that specifically binds to the Fc region of immunoglobulin gamma. It interacts with IgG to initiate cellular responses against pathogens, which is critical for immune regulation. Fc gamma RIIA/CD32a Protein, Human (H167R, HEK293, His) is the recombinant human-derived Fc gamma RIIA/CD32a protein, expressed by HEK293 , with C-6*His labeled tag and H167R mutation.

Background

The Fc gamma RIIA/CD32a protein assumes a pivotal role by specifically binding to the Fc region of immunoglobulins gamma, functioning as a low-affinity receptor. Through its interaction with IgG, Fc gamma RIIA/CD32a initiates cellular responses against pathogens and soluble antigens, illustrating its crucial involvement in immune modulation. Notably, the protein promotes the phagocytosis of opsonized antigens, further contributing to immune defense mechanisms. Additionally, Fc gamma RIIA/CD32a engages in interactions with IGHG1, INPP5D/SHIP1, INPPL1/SHIP2, APCS, FGR, and HCK, indicating its participation in intricate signaling pathways and the regulation of its cellular functions. These multifaceted interactions underscore the significance of Fc gamma RIIA/CD32a in orchestrating diverse immune responses.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

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).
