Recombinant Human Scd40 Ligand 貨號(hào):310-02 細(xì)胞因子

 

胞因子受體存在著可溶性形式，掌握可溶性細(xì)胞因子受體產(chǎn)生的規(guī)律及其生理和病理意義，必將擴(kuò)展人們對(duì)細(xì)胞因子網(wǎng)絡(luò)作用的認(rèn)識(shí)。檢測(cè)細(xì)胞因子及其受體的水平已成為基礎(chǔ)和臨床免疫學(xué)研究中的一個(gè)重要的方面。Catalog Number:

Synonyms:
soluble CD40 Ligand, TNFSF5, TRAP, CD154, gp39, T-BAM
Description:
CD40, a member of the TNF receptor family, is a cell surface protein expressed on B cells, dendritic cells, monocytes, thymic epithelial cells and, at low levels, on T cells. Signaling though CD40 plays an important role in the proliferation and differentiation of B cells, and is critical for immunoglobulin （Ig） class switching. The membrane-anchored CD40-Ligand is expressed almost exclusively on activated CD4+ T lymphocytes. Failure to express CD40L leads to "immunodeficiency with hyper-IgM", a disease characterized by failure to produce IgG, IgA and IgE. The human CD40L gene codes for a 261 amino acid type II transmembrane protein, which contains a 22 amino acid cytoplasmic domain, a 24 amino acid transmembrane domain, and a 215 amino acid extracellular domain. The soluble form of CD40L is an 18 kDa protein comprising the entire TNF homologous region of CD40L and is generated in vivo by an intracellular proteolytic processing of the full length CD40L. Recombinant human soluble CD40 ligand is a 16.3 kDa protein containing 149 amino acid residues comprising the receptor binding TNF-like domain of CD40L.
