Invitrogen™ CD29 (Integrin beta 1) Monoclonal Antibody (TS2/16), Super Bright™ 645, eBioscience™, Invitrogen™

Beschreibung

Description: The 390 monoclonal antibody reacts with mouse CD31, also known as platelet-endothelial cell adhesion molecule-1 (PECAM-1) and gpIIa. This 130-140 kDa surface protein is expressed by endothelial cells and at low levels on all leukocytes and platelets. It has been reported that CD38 binds to CD31. Homotypic interaction of CD31 is important in adhesion, cell-cell and cell-matrix interaction, and signal transduction. Applications Reported: This 390 antibody has been reported for use in flow cytometric analysis. Applications Tested: This 390 antibody has been tested by flow cytometric analysis of mouse bone marrow cells. This may be used at less than or equal to 0.25 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Super Bright 645 is a tandem dye that can be excited with the violet laser line (405 nm) and emits at 645 nm. We recommend using a 660/20 bandpass filter. Please make sure that your instrument is capable of detecting this fluorochrome. When using two or more Super Bright dye-conjugated antibodies in a staining panel, it is recommended to use Super Bright Staining Buffer (Product No. SB-4400) to minimize any non-specific polymer interactions.

CD29, also known as ITGB1 or Integrin Subunit Beta 1, is a 110 kDa cell surface glycoprotein widely expressed by various cells, including all leukocytes. It forms non-covalently linked heterodimers with at least six different alpha integrins (CD49a-f), creating VLA-1 through VLA-6 complexes, as well as with CD51. These alpha-beta integrin heterodimers mediate a range of cellular responses, including adhesion, trafficking, proliferation, and differentiation. CD29-containing integrins bind to extracellular matrix proteins such as collagen, laminin, fibronectin, and vitronectin. Some integrins also interact with cellular receptors like VCAM-1 and MadCAM-1. CD29 plays a crucial role in immune cell trafficking from blood to tissue, particularly during leukocyte emigration and extravascular migration. It is involved in regulating tissue damage and disease symptoms related to inflammatory bowel disease. In the presence of anti-tumor drugs, decreased expression of ITGB1 correlates with multidrug resistance in tumor cells. ITGB1-dependent mechanisms enhance cytokine secretion in human airway smooth muscle in response to IL-1beta, facilitated by fibronectin and type I collagen. More than eight beta subunits with numerous splice variant isoforms have been identified in mammals, including two major forms: beta1A and beta1D. Beta1A is present in all tissues except cardiac and skeletal muscle, which express the beta1D variant.
