Biotinylated Mouse Integrin alpha V beta 8 (ITGAV&ITGB8) Heterodimer Protein, His Tag&Tag Free

Recommended Hot Products:
Based on the high binding affinity between biotin-streptavidin systems, our Streptavidin series products are recommended to use together with biotinylated proteins to get lower non-specific binding results in a shorter time.
  • Synonym
    Integrin alpha V beta 8,ITGAV&ITGB8
  • Source
    Biotinylated Mouse ITGAV&ITGB8 Heterodimer Protein(IT8-M52W7) is expressed from human 293 cells (HEK293). It contains AA Phe 31 - Val 988 & Gly 22 - Leu 681 (Accession # P43406-1 & Q0VBD0-1 ).
    Predicted N-terminus: Phe 31 | Gly 22
  • Molecular Characterization
    Integrin alpha V beta 8 Structure

    Biotinylated Mouse ITGAV&ITGB8 Heterodimer Protein has a calculated MW of 114.2 kDa (ITGAV) & 77.5 kDa (ITGB8). Subunit ITGAV is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and subunit ITGB8 contains no tag but a basic tail at the C-terminus.The protein migrates as 80-90 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

  • Labeling
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • Protein Ratio
    Passed as determined by the HABA assay / binding ELISA.
  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Purity

    >95% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 150 mM NaCl,pH 7.5 with Trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

  • Background
    Integrin alpha V beta 8 (ITGAV & ITGB8 or ITGAVB8) is expressed in yolk sac, placenta, brain perivascular astrocytes, Schwann cells, renal glomerular mesangial cells and pulmonary epithelial cells. Unlike other alpha V integrins, ITGAVB8 does not appear to assume different activation states, and the cytoplasmic tail does not connect to the cytoskeleton. It binds ligands containing an RGD motif, including vitronectin, fibrin and the latency associated peptide (LAP) of the latent TGF-beta complex. High affinity binding of alpha V beta 8 to LAP allows proteolytic cleavage by MT1-MMP, which releases active TGF-beta. This mechanism differs from that of alpha V beta 6, the other alpha V integrin which can activate TGF-beta from latency through non-proteolytic mechanisms. Downstream effects of TGF-beta activation include control of cell growth and associated vascularization.
