Gene name
CD1A-B2M Heterodimer
-
简介
The CD1A 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. CD1A, as a B2M (beta-2-microglobulin) heterodimer, plays a central role in immune surveillance and regulation. CD1A Protein, Human (HEK293, His) is the recombinant human-derived CD1A protein, expressed by HEK293 , with C-His labeled tag.

Stability Test
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.
-
Storage & Shelf Life

Protein Description
The CD1A-B2M heterodimer is a significant component in the immune system, playing a crucial role in the presentation of lipid antigens to T cells. CD1A, a member of the CD1 family of glycoproteins, is primarily expressed on the surface of antigen-presenting cells, including dendritic cells and thymocytes. It is responsible for binding and presenting lipid-based antigens, which are essential for the activation of specific subsets of immune cells, particularly the NKT (Natural Killer T) cells. The association with beta-2-microglobulin (B2M) is critical for the stability and surface expression of the CD1A molecule. Understanding the structure and function of the CD1A-B2M heterodimer can provide insights into various immunological processes and diseases, including autoimmunity, infection, and cancer. Recent advancements in recombinant protein technology have allowed researchers to produce purified CD1A-B2M heterodimers, facilitating studies on their antigen presentation mechanisms and potential therapeutic applications. Investigating this heterodimer is vital for developing novel immunotherapies and vaccines that harness the immune system's capacity to recognize and respond to lipid antigens, thus enhancing our ability to combat infectious diseases and tumors. This research area continues to grow, as elucidating the diverse roles of CD1A-B2M can lead to groundbreaking insights in immunology and therapeutic innovations.
