B2M/Beta-2 microglobulin Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

Beta-2 microglobulin (B2M) is vital in presenting antigens to the immune system through MHC class I molecules. It forms a heterodimer with an alpha chain to create MHC class I molecules. B2M also forms a heterotrimer with MR1 and a metabolite antigen, enhancing antigen presentation and immune recognition. B2M's molecular interactions facilitate immune system functioning and foreign substance recognition. B2M/Beta-2 microglobulin Protein, Mouse (HEK293, His) is the recombinant mouse-derived B2M/Beta-2 microglobulin protein, expressed by HEK293 , with C-His labeled tag.

Description

Beta-2 microglobulin (B2M) is vital in presenting antigens to the immune system through MHC class I molecules. It forms a heterodimer with an alpha chain to create MHC class I molecules. B2M also forms a heterotrimer with MR1 and a metabolite antigen, enhancing antigen presentation and immune recognition. B2M's molecular interactions facilitate immune system functioning and foreign substance recognition. B2M/Beta-2 microglobulin Protein, Mouse (HEK293, His) is the recombinant mouse-derived B2M/Beta-2 microglobulin protein, expressed by HEK293 , with C-His labeled tag.

Background

Beta-2 microglobulin (B2M) protein is a crucial component of the class I major histocompatibility complex (MHC), playing a key role in presenting peptide antigens to the immune system. It forms a heterodimer with an alpha chain, together comprising the major histocompatibility complex class I molecules. Additionally, B2M can form a heterotrimer with MR1 and a metabolite antigen, further contributing to antigen presentation and immune recognition processes. By participating in these molecular interactions, B2M helps in the proper functioning of the immune system and the recognition of foreign substances.

Product Properties

Appearance

Lyophilized powder.

Formulation

1.Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 5% trehalose, 5% mannitol, 0.01% Tween 80.
2.Lyophilized from a 0.22 μm filtered solution of 20 mM PB, 150 mM NaCl, pH 7.4.
Please refer to the lot-specific COA for specific buffer information.

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).

Storage & Stability

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.
