Description: The KN52 antibody reacts with human integrin beta 5, an approximately 100,000 Mr (reduced) and 95,000 Mr (nonreduced) a member of the integrin family. Only a single alpha chain, the alpha v subunit, associates with the integrin beta 5 to form the vitronectin receptor complex. Integrin alpha v/beta 5 complex also binds to the basic domain of Tat (he sequence RKKRRQRRR). The integrin beta 5 is found on carcinoma cell lines, hepatoma and fibroblast cell lines, and is absent from lymphoblastoid cells and platelets.
The KN52 monoclonal antibody has been shown to inhibit migration.
Applications Reported: This KN52 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This KN52 antibody has been pre-titrated and tested by flow cytometric analysis of Chinese Hamster Ovary (CHO), A549 and normal human peripheral blood cells. This can be used at 5 µL (0.06 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.
Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser.
Filtration: 0.2 µm post-manufacturing filtered.
Integrins are important extracellular matrix (ECM) receptor proteins located on cell surfaces. They are hetrodimers composed of an alpha and a beta transmembrane glycoprotein subunit. Around 22 different integrins (different alpha/ beta subunit combinations) are found in nature. Integrins are generally present in high concentrations at the cell surface, but, unlike most other cell-surface receptors, they bind ligands with very low affinity. Due to their weak individual binding, integrins need to cluster and bind in-groups in order to effectively bind the ECM. Integrins bind many different ligands including laminin. Each integrin is made up of a large N-terminal extracellular domain that binds the ECM ligand and a small C-terminal cytoplasmic domain that mediates interaction with the actin cytoskeleton and signaling function.
