Biotinylated Human Integrin alpha V beta 1 (ITGAV&ITGB1) Heterodimer Protein, His,Avitag™&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.

  • Source
    Biotinylated Human ITGAV&ITGB1 Heterodimer Protein, His,Avitag&Tag Free (IT1-H82W6) is expressed from human 293 cells (HEK293). It contains AA Phe 31 - Val 992 (ITGAV) & Gln 21 - Asp 728 (ITGB1) (Accession # NP_002201.1(ITGAV) & NP_002202.2(ITGB1)).
    Predicted N-terminus: Phe 31 (ITGAV) & Gln 21 (ITGB1)
  • Molecular Characterization
    Online(Phe 31 - Val 992 (ITGAV) & Gln 21 - Asp 728 (ITGB1)) NP_002201.1 (ITGAV) & NP_002202.2 (ITGB1)

    Biotinylated Human ITGAV&ITGB1 Heterodimer Protein, His,Avitag&Tag Free, produced by co-expression of ITGAV and ITGB1, has a calculated MW of 114.7 kDa (ITGAV) and 83.7 kDa (ITGB1). Subunit ITGAV is fused with an acidic tail at the C-terminus and followed by a polyhistidine tag and an Avi tag (Avitag™) and subunit ITGB1 contains no tag but a basic tail at the C-terminus. The non-reducing (NR) protein migrates as 135-150 kDa (ITGAV) and 100-115 kDa (ITGB1) respectively due to glycosylation.

  • Biotinylation
    Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
  • 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. Normally trehalose is added as protectant before lyophilization.

    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

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

  • Background
    Integrin alpha-5/beta-1 is a receptor for ibrinogen. Integrin alpha-1/beta-1, alpha-2/beta-1, alpha-6/beta-1 and alpha-7/beta-1 are receptors for lamimin. Integrin alpha-4/beta-1 is a receptor for VCAM1. It recognizes the sequence Q-I-D-S in VCAM1. Integrin alpha-9/beta-1 is a receptor for VCAM1, cytotactin and osteopontin. It recognizes the sequence A-E-I-D-G-I-E-L in cytotactin. Integrin alpha-V/beta-1 is also a receptor for vitronectin. Beta-1 integrins recognize the sequence R-G-D in a wide array of ligands. Isoform 2 interferes with isoform 1 resulting in a dominant negative effect on cell adhesion and migration (in vitro). When associated with alpha-7/beta-1 integrin, regulates cell adhesion and laminin matrix deposition.
