CD4 Mouse Anti-Rat, BUV395, Clone: OX-38, BD Optibuild™

Description

• The OX-38 antibody specifically recognizes the CD4 antigen on most thymocytes, a subpopulation of mature T lymphocytes (ie, MHC class II-restricted T cells, including most T helper cells), monocytes, macrophages, and some dendritic cells
• CD4 is an antigen coreceptor on the T-cell surface which interacts with MHC class II molecules on antigen-presenting cells
• It participates in T-cell activation through its association with the T-cell receptor complex and protein tyrosine kinase lck
• The OX-38 antibody has been reported to bind to the same epitope of CD4 as that recognized by W3/25 mAb, which is a different epitope than that recognized by OX-35 mAb
• In vivo blocking of some cell-mediated immune responses by mAb OX-38 has been reported
• Injection of OX-38 mAb induces allograft unresponsiveness in rats, with varying results depending on the rat strain used (high or low responder)
• Furthermore, in vivo depletion of CD4+ lymphocytes has been reported with this antibody
• 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.
