Azide-labeled B7-H4

简介
The B7-H4 protein acts as a negative regulator and inhibits T cell-mediated immune responses, including activation, proliferation, cytokine production, and cytotoxicity. Significant significance can be observed when expressed on tumor macrophages, cooperating with regulatory T cells (Tregs) to suppress tumor-associated antigen-specific T cell immunity. Azide-labeled B7-H4 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Azide-labeled B7-H4 protein, expressed by HEK293, with C-His labeled tag.

稳定性测试
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.

背景信息
CD1B is a member of the CD1 family of glycoproteins that play a crucial role in the immune system by presenting lipid antigens to T cells. Unlike classical MHC (Major Histocompatibility Complex) molecules, CD1B is specialized in the presentation of non-peptide antigens, including lipids and glycolipids derived from various pathogens. This ability is particularly important for the immune response against certain bacteria, such as Mycobacterium tuberculosis, which has unique lipid components that evade detection by conventional T cells. Research into recombinant CD1B proteins has gained momentum due to their potential applications in vaccine development and immunotherapy, particularly for diseases where conventional peptide-based vaccines are less effective. By studying CD1B and its interactions with T cell receptors, researchers aim to understand its unique antigen-presentation mechanisms and leverage this knowledge to develop innovative strategies for enhancing immune responses against specific pathogens. Furthermore, recombinant CD1B proteins can serve as valuable tools for elucidating the role of lipid antigens in immune responses, ultimately contributing to the design of targeted immunotherapies for infectious diseases and cancer. These insights may also extend to the understanding of autoimmune diseases, where lipid dysregulation may play a role. The ongoing exploration of CD1B emphasizes its importance in the intersection of lipid biology and immunology, marking it as a significant focus area for future research and therapeutic development.
