Anti-Human CD49d (9F10) ColorWheel^® Dye-Ready mAb

ColorWheel^® technology is a novel and proprietary method of creating your own antibody and dye combinations for use in flow cytometry. By incubating any ColorWheel^® antibody with any ColorWheel^® dye, researchers can quickly and simply produce primary conjugated antibodies for use in single color or multicolor flow cytometry analysis. Each ColorWheel^® antibody and dye is lyophilized for long-term storage, allowing for simplicity and flexibility without compromise. ColorWheel^® technology requires both ColorWheel^® antibody and ColorWheel^® dye for Flow Cytometry application.

Integrin alpha-4 (UniProt: P13612; also known as CD49 antigen-like family member D, Integrin alpha-IV, VLA-4 subunit alpha, CD49d) is encoded by the ITGA4 (also known as CD49D) gene (Gene ID: 3676) in human. Integrins are heterodimers composed of a variable a-subunit of 150-170 kDa and a conserved 95 kDa b subunit. They contain a large extracellular domain responsible for ligand binding, a single transmembrane domain, and a cytoplasmic domain. The exact combination of various a- and b-subunits dictates the binding specificity of integrins to different ECM components. Although both subunits are required for adhesion, the binding specificity primarily depends on the extracellular portion of the a-subunit. Integrins bind to their ligands with a low affinity and this binding occurs only when a certain minimal number of integrins are present at specific points known as focal contacts and hemidesmosomes. In response to specific stimuli, they cluster in focal contacts and their combined affinities create a region on the cell surface, which presents sufficient adhesive capacity to adhere to the ECM. This allows cells to bind to a large numbers of matrix molecules simultaneously while still maintaining their ability to explore their environment without losing all attachmentsCD49d is a single-pass type I membrane glycoprotein that is synthesized with a signal peptide (aa 1-33), which is subsequently cleaved off to produce the mature form that contains a large extracellular domain (aa 34-977), a transmembrane domain (aa 978-1001), and a short cytoplasmic tail (aa 1002-1032). CD49d plays a critical role in leucocyte trafficking, activation, and survival, and also facilitates interactions between leucocytes and stromal cells found in the marrow or germinal center of lymphoid follicles via VCAM-1 and fibronectin. It also serves as a signalling receptor that influences B-cell survival via upregulation of Bcl-2 family members. CD49d/CD29 and CD49d/Integrin 7 are known to be receptors for fibronectin. They recognize one or more domains within the alternatively spliced CS-1 and CS-5 regions of fibronectin. They also serve as receptors for VCAM1. CD40d/CD29 recognizes the sequence Q-I-D-S in VCAM1.
