CCR8 (CD198) Mouse anti-Human, Brilliant Violet 421, Clone: 433H, BD
Mouse Monoclonal Antibody
Manufacturer: BD Biosciences 566379
The 433H monoclonal antibody specifically binds to C-C chemokine receptor type 8 (CC-CKR-8 or CCR8) which is also known as CD198, GPRCY6, CY6, CKRL1, CMKBR8, CMKBRL2, or TER1. CCR8 (CD198) is a seven-transmembrane, G-protein-coupled, glycoprotein receptor that belongs to the beta chemokine receptor family. CCR8 is expressed on monocytes, macrophages, eosinophils, Langerhans cells, thymocytes, and vascular smooth muscle cells. It is preferentially expressed on some T cell subsets including skin resident memory T cells, type 2 T-helper (Th2-like) cells, and T regulatory cells. CCR8 is a receptor for the chemokine C-C motif chemokine 1 (CCL1), also known as SCYA1 or I-309, and plays a role in regulating monocyte and T cell chemotaxis and thymocyte apoptosis. CCR8 may play a role in lung T cell recruitment in asthma and can serve as an alternative coreceptor to CD4 for HIV-1 infection. The 433H antibody reportedly neutralized the chemotactic response of cultured T cells to CCL1.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 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.
