CD335 Rat anti-Mouse, Brilliant Violet 421, Clone: 29A1.4, BD

Description

• The monoclonal antibody 29A1.4 specifically binds to mouse CD335, also known as NKp46
• NKp46 is a 46 kDa type I transmembrane glycoprotein that is a member of the natural cytotoxicity receptor (NCR) family and immunoglobulin superfamily
• NKp46 is encoded by the Ncr1 gene located on chromosome 7
• NKp46 functions as a cytotoxicity triggering receptor and is selectively expressed by immature and mature NK cells in all mouse strains tested
• NKp46 is detected on a minute fraction of NK-like T cells (less than 2% of NKp46+ express CD3e) but not on CD1d-restricted NKT cells from C57BL/6 mice
• When immobilized on tissue culture plates, the 29A1.4 antibody reportedly stimulates NK cells to produce interferon-gamma and to release their cytoplasmic granule contents
• Although the ligands for the NKp46 receptor have not been fully characterized, recent evidence indicates that this receptor plays an important role in the NK cell-mediated recognition and killing of some virus-infected cells and tumor cells
• The immunogen used to generate the 29A1.4 clone was mouse NKp46-Fc recombinant protein
• The antibody was conjugated to BD Horizon™ BV421 which is part of the BD Horizon™ Brilliant Violet™ family of dyes
• With an Ex Max of 407-nm and Em Max at 421-nm, BD Horizon™ BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50-nm filter)
• BD Horizon™ BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue™ conjugates.
