CD158b Mouse anti-Human, Brilliant Violet 605, Clone: CH-L, BD Optibuild™

Description

• The CH-L monoclonal antibody specifically binds to CD158b proteins
• These proteins are 50-58 kDa type I glycoproteins that belong to the Killer cell immunoglobulin-like receptor (KIR) family: (KIR2DL2/L3/S2)
• They are also known as CD158b1 (KIR2DL2; NKAT-6; p58.2), CD158b2 (KIR2DL3; NKAT-2; p58.2), or CD158j (KIR2DS2; NKAT-5; p50.2)
• The CD158b molecules are composed of two extracellular Ig-like domains, and a transmembrane region
• CD158b1 and CD158b2 also possess long (84 or 76 amino acids, respectively) cytoplasmic tailswith two immunoreceptor tyrosine-based inhibition motifs (ITIM) whereas CD158j has a short (39 amino acid) cytoplasmic tail that lacks the ITIM motif
• CD158b molecules are expressed on NK cells and subsets of TCR αβ+ cells or TCR γδ+ cells
• Ligand- or CH-L antibody-bound CD158b1 or CD158b2 can reportedly inhibit cytolytic NK and T cell responses to various stimuli including certain target cells expressing MHC class I ligands encoded by HLA-C alleles (Cw 1, 3, 7 and 8)
• CD158j reportedly can enhance some cellular cytolytic responses
• This antibody is conjugated to BD Horizon™ BV605 which is part of the BD Horizon Brilliant™ Violet family of dyes
• With an Ex Max of 407nm and Em Max of 602nm, BD Horizon BV605 can be excited by a violet laser and detected with a standard 610/20nm filter set
• BD Horizon BV605 is a tandem fluorochrome of BD Horizon BV421 and an acceptor dye with an Em max at 605nm
• Due to the excitation of the acceptor dye by the green (532 nm) and yellow-green (561 nm) lasers, there will be significant spillover into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers
• BD Horizon BV605 conjugates are very bright, often exhibiting brightness equivalent to PE conjugates and can be used as a third color off of the violet laser
• BV605 is a tandem fluorochrome that combines BD Horizon BV421 and Cy™3.5
• These conjugates are very bright, exhibiting similar brightness to equivalent PE conjugates
• Due to the excitation of Cy3.5 by the green (532nm) and yellow-green (561nm) lasers, there will be significant spillover of the BD Horizon BV605 signal into the PE and BD Horizon PE-CF594 detectors off the green or yellow-green lasers.
