GARP Mouse anti-Human, Brilliant Violet 510, Clone: 7B11 (also known as CMSSC-7B11), BD Optibuild™

Description

• The 7B11 (also known as CMSSC-7B11) monoclonal antibody specifically binds to human GARP (Glycoprotein A repetitions predominant)
• The LRRC32 /(Leucine rich repeat containing 32) gene encodes the 662 amino acid-residue, 80 kDa transmembrane GARP glycoprotein that has an extracellular region composed primarily of 20 leucine-rich repeats
• GARP is specifically expressed on Treg cells activated through the T cell receptor (TCR)
• Ectopic expression of GARP in human naοve T cells inhibited their proliferation and cytokine secretion upon TCR activation
• Remarkably, GARP over-expression in naοve T cells induced expression of FoxP3 and endowed them with a partial suppressive function
• The extracellular, but not the cytoplasmic region, of GARP was necessary for these functions
• GARP serves as a receptor for latent TGF-beta which may play a role in the suppressive action of Treg cells
• GARP is also expressed on platelets and other tissues, however the function on these cells is not known
• 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 405nm and Em Max at 510nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50nm) filter set
• BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser
• BV510 is a polymer-based dye that is brighter than BD Horizon V500
• Due to similar excitation and emission properties, BD Horizon BV510 and BD Horizon V500 cannot be used simultaneously.
