CD158f Mouse anti-Human, Brilliant Violet 421, Clone: UP-R1, BD
Mouse Monoclonal Antibody
Manufacturer: BD Biosciences 566330
The UP-R1 monoclonal antibody specifically recognizes CD158f which is also known as KIR2DL5. CD158f is a ñ60 kDa single-pass type I transmembrane glycoprotein that belongs to the KIR (Killer cell Ig-like receptors) family within the Ig gene superfamily. CD158f is encoded by two gene paralogs, KIR2DL5A and KIR2DL5B /that show greater than 99% identity in their coding sequences. /CD158f molecules contain two extracellular C2-type Ig-like domains and a long cytoplasmic domain containing one canonical immunoreceptor tyrosine-based inhibitory motif (ITIM) and another atypical ITIM sequence. Although the exact ligands for CD158f have not yet been identified, the inhibitory function of UP-R1 antibody-crosslinked CD158f was shown to primarily depend upon a Src homology region 2-containing protein tyrosine phosphatase-2 (SHP-2) -dependent pathway. CD158f is highly polymorphic and is expressed on subsets of NK cells and T lymphocytes by some individuals. UP-R1 recognizes cell surface CD158f encoded by the most commonly expressed allele, KIR2DL5A*001 . The UP-R1 antibody has been predicted to recognize CD158f molecules encoded by other transcriptionally-active KIR2DL5 alleles, A*012 and B*00602The antibody was conjugated to BD Horizon BV421 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 407nm and Em Max at 421nm, BD Horizon BV421 can be excited by the violet laser and detected in the standard Pacific Blue™ filter set (eg, 450/50nm filter). BD Horizon BV421 conjugates are very bright, often exhibiting a 10 fold improvement in brightness compared to Pacific Blue conjugates. BV421 is a polymer-based dye excited by the violet laser and is one of the brightest fluorochromes offered by BD Biosciences. Conjugates are typically 10 times brighter than Pacific Blue™ conjugates and are often as bright as or brighter than PE conjugates. Due to nearly identical excitation and emission properties but different spillover characteristics, BD Horizon BV421, Pacific Blue™, and BD Horizon™ V450 cannot be used simultaneously.
