Vγ 3 TCR Hamster anti-Mouse, Brilliant Violet 510, Clone: 536, BD Optibuild™

Description

• The 536 monoclonal antibody specifically recognizes Vγ3† T-cell Receptor (TCR)-bearing T lymphocytes, which are the predominantγδTCR-bearing cells in the early fetal thymus and the adult epidermis of euthymic mice
• The first T cells to mature in the embryonic thymus express the Vγ3 and Vδ1 TCR chains, and their development is dependent upon IL-7
• There is evidence that the Vγ3 TCR-bearing fetal thymocytes are the precursors of the majority of dendritic epidermal T cells (DEC), which may be replenished in the adult by proliferation in situ /rather than by seeding from primary lymphoid organs
• Although the Vγ3 TCR is almost exclusively found in the DEC population, it has been shown that the homing of DEC to the epidermis does not require expression of the Vγ3 gene segment
• Vγ3 TCR-bearing dermal dendritic cells have also been described
• Vγ3 TCR has also been found on a subset of T lymphocytes in the lactating mammary gland and at the site of antigenic challenge in contact-sensitized mice
• Plate-bound 536 antibody activates Vγ3 TCR-bearing T cells, and Fab fragments of mAb 536 block in vitro /stimulation of DEC by keratinocytes
• 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.
