The 10D5 monoclonal antibody specifically recognizes Integrin alpha v beta 6 (αvβ6) that is also known as CD51/β6. This heterodimeric receptor is comprised of transmembrane type I alpha and beta chain glycoproteins that are encoded by ITGAV (integrin subunit alpha) and ITGB6 (integrin subunit beta 6), respectively. Like other integrins, αvβ6 serves as a transmembrane adhesion receptor that can tether the intracellular cytoskeleton to the extracellular matrix (ECM) by binding to R-G-D sequences of ECM protein ligands including fibronectin, vitronectin, and tenascin. Integrin αvβ6 likewise plays a key role in the activation of transforming growth factor beta-1 (TGFβ1) by its R-G-D-dependent release of TGFβ1 from regulatory Latency-associated peptide (LAP). Some viruses, such as. Coxsackieviruses and Herpes simplex virus-1 use Integrin αvβ6 as a receptor to infect cells. Integrin αvβ6 engages in bidirectional signaling, ie, outside-in and inside-out signaling, to regulate essential cellular functions. These include adhesion, migration, polarization, differentiation, and proliferation that are crucial to tissue homeostasis. Although not normally expressed on adult epithelial cells/keratinocytes, its expression is upregulated on these cells during the course of embryonic development, inflammation, tissue injury, wound healing, as well as malignant transformation. The 10D5 antibody blocks Integrin αvβ6-dependent cellular adhesion and migration and reportedly recognizes both human and mouse αvβ6 integrins. Binding of 10D5 antibody to αvβ6 is divalent-cation dependent.
The antibody was conjugated to BD Horizon™ BV510 which is part of the BD Horizon Brilliant™ Violet family of dyes. With an Ex Max of 405-nm and Em Max at 510-nm, BD Horizon BV510 can be excited by the violet laser and detected in the BD Horizon V500 (525/50-nm) filter set. BD Horizon BV510 conjugates are useful for the detection of dim markers off the violet laser.
