Paraffin embedded prostate chippings stained with Human anti Human CD276 (HCA143) after antigen retrieval with citrate followed by Mouse anti strep-tag immo (MCA2488) and Histar detection system (STAR3000A)
Human anti Human CD276 antibody, clone 11434 detects CD276, a member of the B7 family of co-stimulatory molecules also known as B7-H3. CD276 is a type I transmembrane protein that induces the proliferation of CD4+ and CD8+ T cells, enhances the generation of cytotoxic T cells and selectively stimulates the production of interferon gamma.
Expression of CD276 can be induced on dendritic cells and monocytes by inflammatory cytokines, and is also widely expressed in peripheral tissues including the heart, kidney, testis and colon. In humans, CD276 exists as two isoforms which result from gene duplication and differential splicing.
CD276 is reported to have therapeutic potential for the regulation of cell-mediated immune responses to cancer, particularly in conjunction with anti-angiogenic therapy(Kraan et al. 2014).
A monovalent human recombinant Fab selected from the HuCAL® phage display library, expressed in E. coli. The antibody is tagged with V5 and a double extended Strep-tag at the C-terminus of the antibody heavy chain. This antibody is supplied lyophilised.
