The H57-597 monoclonal antibody is specific for the beta chain of the mouse T cell Receptor (TCR). The crosslinking induces activation and proliferation of T cells, as a plate-bound or a soluble H57-597, or the plate-bound antibody can induce apoptosis, based on assay conditions. The beta chain of the TCR can combine with the alpha chain of the receptor to produce the alpha-beta TCR, which is expressed by the NKT cells, by the NK1.1+ thymocytes and most of the T cells. The beta chain does not react with the gamma-delta TCR-bearing cells, expressed by a small number of T cells. This antibody can be used as a phenotypic marker for the TCR beta expressing cells or for the functional purpose of TCR-mediated cell activation or apoptosis.BG Violet 450 conjugate is an alternative to the Pacific Blue, eFluor 450, or BD Horizon V450 dyes. It is excited by the violet (405 nm) laser, with a peak emission of 450nm.

The 53-6.7 monoclonal antibody specifically reacts with Ly-2, the 38 kDa alpha chain, and with Lyt-2, the 34 kDa alpha’ chain, of the mouse CD8 antigen.

The RA3-6B2 monoclonal antibody specifically reacts with a 220 kDa exon A-restricted epitope on the extracellular domain of mouse CD45 glycoprotein. CD45R/B220 is expressed on all the development stages of B cells, and at a low level on plasma cells and a subset of memory B cells. Low levels of CD45R/B220 are also expressed by some activated T lymphocytes, natural killer cell progenitors in the bone marrow, lymphokine activated killer cells (LAK), T lymphocytes of lpr/lpr mutant mouse, apoptotic T cells of mice injected with bacterial superantigens, and macrophage progenitors in fetal liver.The CD45 molecule is a member of the Protein Tyrosine Phosphatase (PTP) family, because its intracellular region contains two PTP domains. The extracellular region’s variability is caused by different levels of glycosylation, and the splicing of the 4, 5, and 6 exons. The isoforms found in the mouse strains depend on the activation state, maturation stage and cell type, and are very important in B and T lymphocytes antigen receptor signal transduction.The RA3-6B2 antibody inhibits in vivo B lymphocytes responses and enhances isotype switching during in vitro B lymphocyte responses.
