Invitrogen™ CD29 (Integrin beta 1) Monoclonal Antibody (eBioHMb1-1 (HMb1-1)), FITC, eBioscience™, Invitrogen™

Beskrivelse

Description: The eBioHMb1-1 monoclonal antibody reacts with mouse and rat CD29 (integrin beta 1), a 110-120 kDa member of the beta integrin family expressed by leukocytes, endothelial, smooth muscle and epithelial cells. CD29 binds non-covalently with the alpha integrins CD49a-f to form the VLA-1 through VLA-6 complexes, as well as with CD51. These alpha-beta integrin heterodimers are capable of mediating a variety of cellular responses including adhesion, trafficking, proliferaton and differentiation. All integrins which include CD29 bind to extracellular matrix proteins including collagen, laminin, fibronectin and vitronectin, whereas some CD29-containing integrins can also interact with cellular receptors such as VCAM-1 and MadCAM-1. Applications Reported: This eBioHMb1-1 (HMb1-1) antibody has been reported for use in flow cytometric analysis. Applications Tested: This eBioHMb1-1 (HMb1-1) antibody has been tested by flow cytometric analysis of mouse bone marrow cells. This can be used at less than or equal to 1 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. Excitation: 488 nm; Emission: 520 nm; Laser: Blue Laser. Filtration: 0.2 μm post-manufacturing filtered.

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.
