{"product_id":"nsj-v7421-20ug","title":"HLA-DR Antibody (MHC II), 20 ug","description":"\u003cp\u003eMajor histocompatibility complex (MHC) class II molecules destined for presentation to CD4+ helper T cells is determined by two key events. These events include the dissociation of class II-associated invariant chain peptides (CLIP) from an antigen binding groove in MHC class II\/ dimers through the activity of MHC molecules HLA-DM and -DO, and subsequent peptide antigen binding. Accumulating in endosomal\/lysosomal compartments and on the surface of B cells, HLA-DM, -DO molecules regulate the dissociation of CLIP and the sub- sequent binding of exogenous peptides to HLA class II molecules (HLA-DR, -DQ and -DP) by sustaining a conformation that favors peptide exchange. RFLP analysis of HLA-DM genes from rheumatoid arthritis (RA) patients suggests that certain polymorphisms are genetic factors for RA susceptibility. HLA-B belongs to the HLA class I heavy chain paralogs. Class I molecules play a central role in the immune system by presenting peptides derived from the endoplasmic reticulum lumen. HLA-B and -C can form heterodimers consisting of a membrane anchored heavy chain and a light chain. Polymorphisms yield hundreds of HLA-B and -C alleles.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"20 ug","offer_id":48534345253088,"sku":"V7421-20UG","price":259.0,"currency_code":"KRW","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0601\/9330\/8896\/files\/get_image_e58db6ad-4ad5-4a97-b55b-7c59f4b91665.jpg?v=1768274161","url":"https:\/\/rndmate.com\/products\/nsj-v7421-20ug","provider":"알앤디메이트","version":"1.0","type":"link"}
