CD45R Mouse Anti-Rat, BUV395, Clone: HIS24, BD Optibuild™

Description

• The HIS24 antibody reacts with a developmentally regulated form of CD45 found on most B lymphocytes, including developing B cells in the bone marrow and peripheral B cells, but not plasma cells
• The level of expression of this CD45R antigen appears to be an indicator of both maturational stages in the B-cell lineage and of functionally distinct B-cell subsets
• The HIS24 mAb, in combination with other markers such as TdT and Ig expression, is effective in the identification of B-cell progenitors
• CD45 is a member of the Protein Tyrosine Phosphatase (PTP) family: Its intracellular (COOH-terminal) region contains two PTP catalytic domains, and the extracellular region is highly variable due to alternative splicing of exons 4, 5, and 6 (designated A, B, and C, respectively), plus differing levels of glycosylation
• The CD45 isoforms detected in the rat are cell type-, maturation-, and activation state-specific
• The CD45 isoforms play complex roles in T-cell and B-cell antigen receptor signal transduction
• The antibody was conjugated to BD Horizon™ BUV395 which is part of the BD Horizon Brilliant™ Ultraviolet family of dyes
• This dye has been exclusively developed by BD Biosciences to have minimal spillover into other detectors, making it an optimal choice for multicolor flow cytometry
• With an Ex Max at 348 nm and an Em Max at 395 nm, BD Horizon BUV395 can be excited with a 355 nm laser and detected with a 379/28 filter
• BUV395 is a UV-excitable dye that has been developed exclusively by BD Biosciences
• With an excitation max of 348 nm and emission max of 395 nm, BUV395 can be excited by the 355nm laser and detected in a 379/28 filter
• This dye is optimal for multicolor flow cytometry because it has little to no spillover into other detectors.
