The SN2 monoclonal antibody specifically recognizes a 37-42 kDa membrane glycoprotein expressed on a subset of peripheral lymphocytes, monocytes, immature thymocytes and on most platelets. CD165, also known as gp37 or AD2, is expressed at low levels on most thymocytes and thymic epithelial cells. CD165 has been detected on islet cells of the pancreas, Bowman's capsule of the kidney and on central nervous system neurons. SN2 antigen has been reported to be identical, or very similar, to the T-cell acute lymphoblastic leukemia antigen, TALLA-1. CD165 has been reported to play a role in the adhesion between thymocytes and thymic epithelial cells during development.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
