The TX83 monoclonal antibody specifically recognizes Allergin-1 which is also known as Allergy inhibitory receptor 1 or Mast cell antigen 32 (Mast cell Ag-32/ Mca32). Allergin-1 is a ñ60 kDa type I transmembrane glycoprotein that is encoded by Milr1 /(Mast cell immunoglobulin like receptor 1) and contains two cytoplasmic immunoreceptor tyrosine-based inhibitory motifs. Allergin-1 is expressed on mast cells as well as some dendritic cells, macrophages, and neutrophils. When ligated with FcεRI, Allergin-1 inhibits FcεRI-mediated degranulation of mast cells which suppresses immediate hypersensitvity reactions.

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.
