The Y129 monoclonal antibody specifically binds to CD317 which is also known as Bone marrow stromal antigen 2 (BST2). CD317 is a type II transmembrane glycoprotein that belongs to the Tetherin family. CD317 is an interferon (IFN)-induced protein that is expressed on monocytes, granulocytes, dendritic cells, B lymphoblasts, plasma cells, T cells, natural killer (NK) cells, stromal cells and myeloma cells. CD317 is expressed by nonhematopoietic cells including cells within solid tumors derived from breast, lung and kidney. CD317 may be involved in the interactions between bone marrow stromal cells and lymphocytes. It is likewise known as Tetherin and reportedly blocks the release of some enveloped viruses by tethering virions to infected cell membranes. CD317 stimulates signaling by CD85g (ILT7) and may provide negative feedback for interferon (IFN) production by plasmacytoid dendritic cells during viral infections.

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.
