内毒素: Less than 0.01 EU per μg by the LAL method. 纯度: >95% as determined by SDS-PAGE. 活性: Immobilized Human B7-2, Fc Tag (Cat. No. CD6-H5257) at 2μg/mL (100 μL/well) can bind Human CTLA-4, His Tag, low endotoxin (Cat. No. CT4-H522a) with a linear range of 1-6.4 ng/mL (Routinely tested). 产品背景: CTLA-4 (Cytotoxic T-Lymphocyte Antigen 4) is also known as CD152 (Cluster of differentiation 152), is a protein receptor that downregulates the immune system. CTLA4 is a member of the immunoglobulin superfamily, which is expressed on the surface of Helper T cells and transmits an inhibitory signal to T cells. The protein contains an extracellular V domain, a transmembrane domain, and a cytoplasmic tail. Alternate splice variants, encoding different isoforms. CTLA4 is similar to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T cells and may be important to their function. T cell activation through the T cell receptor and CD28 leads to increased expression of CTLA-4, an inhibitory receptor for B7 molecules. Fusion proteins of CTLA4 and antibodies (CTLA4-Ig) have been used in clinical trials for rheumatoid arthritis. 产品描述: This protein carries a polyhistidine tag at the C-terminus. The protein has a calculated MW of 15.4 kDa. The protein migrates as 25-30 kDa under reducing (R) condition (SDS-PAGE) due to different extent glycosylation. 因为难以在供应系统上进行数据同步,所以了解更多产品规格及产品数据,请移步: http://www.acrobiosystems.cn/P1299-Human_CTLA-4_%7C_CD152_Protein_low_endotoxin.html
