The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use 5µl for 106 cells. ab126026-Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.
FunctionIntegrin alpha-3/beta-1 is a receptor for fibronectin, laminin, collagen, epiligrin, thrombospondin and CSPG4. Alpha-3/beta-1 may mediate with LGALS3 the stimulation by CSPG4 of endothelial cells migration.
Tissue specificityIsoform alpha-3A is widely expressed. Isoform alpha-3B is expressed in brain and heart. In brain, both isoforms are exclusively expressed on vascular smooth muscle cells, whereas in heart isoform alpha-3A is strongly expressed on vascular smooth muscle cells, isoform alpha-3B is detected only on endothelial vein cells.
Sequence similaritiesBelongs to the integrin alpha chain family. Contains 7 FG-GAP repeats.
Post-translational modificationsIsoform alpha-3A, but not isoform alpha-3B, is phosphorylated on serine residues. Phosphorylation increases after phorbol 12-myristate 13-acetate stimulation. Isoform alpha-3A is phosphorylated on Tyr-1051.
