Biotinylated Human Neuropilin-1 / NRP1 / CD304 Protein, His Tag & Avi Tag (Avitag™)

  • Synonym
    NRP1,Neuropilin-1,NRP,VEGF165R,CD304
  • Source
    Biotinylated Human NRP1, His Tag (NR1-H82E3) is expressed from human 293 cells (HEK293). It contains AA Phe 22 - Lys 644 (Accession # O14786-1(V179A)).
    Predicted N-terminus: Phe 22
  • Molecular Characterization
    NRP1(Phe 22 - Lys 644) O14786-1(V179A)

    This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag.

    The protein has a calculated MW of 73.5 kDa. The protein migrates as 90-100 kDa under reducing (R) condition (SDS-PAGE) 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
    The biotin to protein ratio is 0.5-1 as determined by the HABA assay.
  • 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 PBS, pH7.4. 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.

    Please avoid repeated freeze-thaw cycles.

    No activity loss is observed after storage at:

    1. 4-8°C for 12 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.

Immobilized Human VEGF165, Tag Free (Cat. No. VE5-H4210) at 2 μg/mL (100 μL/well) can bind Biotinylated Human NRP1, His Tag (Cat. No. NR1-H82E3) with a linear range of 0.5-16 ng/mL (QC tested).

  • Background
    Neuropilin-1 (NRP1) is also known as Vascular endothelial cell growth factor 165 receptor (VEGF165R), CD antigen CD304, which belongs to the neuropilin family. The membrane-bound isoform 1 is a receptor involved in the development of the cardiovascular system, in angiogenesis, in the formation of certain neuronal circuits and in organogenesis outside the nervous system. It mediates the chemorepulsant activity of semaphorins. It binds to semaphorin 3A, The PLGF-2 isoform of PGF, The VEGF-165 isoform of VEGF and VEGF-B. Coexpression with KDR results in increased VEGF-165 binding to KDR as well as increased chemotaxis. It may regulate VEGF-induced angiogenesis. The soluble isoform 2 binds VEGF-165 and appears to inhibit its binding to cells.
