CD38 Rat anti-Mouse, BB700, Clone: 90/CD38 (also known as Ab90), BD Optibuild™

Description

The 90 monoclonal antibody specifically binds to CD38, a 42 kDa transmembrane glycoprotein on immature and mature, resting and activated, B lymphocytes. In contrast to humans, CD38 expression is down-regulated on mouse germinal center B cells and plasma cells. CD38 is also expressed on a subpopulation of thymic and peripheral T cells, NK cells, and splenic macrophages. Furthermore, CD38 has been detected on bone marrow-derived hematopoietic stem cells. The CD38 molecule is reported to exhibit both cyclase and hydrolase activities and plays a role in lymphocyte activation. CD31, both human and mouse, is reported to be a ligand for human CD38.

The antibody was conjugated to BD Horizon™ BB700, which is part of the BD Horizon Brilliant™ Blue family of dyes. It is a polymer-based tandem dye developed exclusively by BD Biosciences. With an excitation max of 485 nm and an emission max of 693 nm, BD Horizon BB700 can be excited by the 488 nm laser and detected in a standard PerCP-Cy™5.5 set (eg, 695/40nm filter). This dye provides a much brighter alternative to PerCP-Cy5.5 with less cross laser excitation off the 405 nm and 355 nm lasers.BD Horizon Brilliant™ Blue 700 (BB700) is a dye that was exclusively developed by BD Biosciences as brighter alternative to PerCP-Cy5.5. This dye also has less cross laser excitation off the 405 nm laser, resulting in less spillover into the violet channels compared to PerCP-Cy5.5.  Due to similar excitation and emission properties, BD Horizon BB700 and PerCP-Cy5.5 cannot be used simultaneously.
