CD1B Protein, Human (HEK293, Fc)

The CD1B protein is a key antigen-presenting molecule that binds self- and non-self lipid and glycolipid antigens and presents them to T-cell receptors on natural killer T cells. As a B2M (beta-2-microglobulin) heterodimer, CD1B is crucially involved in immune surveillance and responses. CD1B Protein, Human (HEK293, Fc) is the recombinant human-derived CD1B protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CD1B Protein, Human (HEK293, Fc) is 286 a.a., with molecular weight of 60-90 kDa.

The CD1B protein serves as a key antigen-presenting molecule, demonstrating the ability to bind both self and non-self lipid and glycolipid antigens, thereby facilitating their presentation to T-cell receptors on natural killer T-cells. Forming a heterodimeric complex with B2M (beta-2-microglobulin), this protein plays a crucial role in immune surveillance and response. Its interaction with saposin C further enhances its functional repertoire, contributing to the intricate processes underlying T-cell recognition and activation in response to a diverse array of antigens.

  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, 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. 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.
