Biotinylated Influenza A [A/Hong Kong/483/97(H5N1)] Hemagglutinin 1 (HA1) Protein, Avitag™,His Tag

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 Influenza A [A/Hong Kong/483/97(H5N1)] HA1, Avitag,His Tag (HA1-V82E4) is expressed from human 293 cells (HEK293). It contains AA Asp 17 - Arg 339 (Accession # AAC32099.1).
    Predicted N-terminus: Asp 17
  • Molecular Characterization
    Online(Asp 17 - Arg 339) AAC32099.1

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

    The protein has a calculated MW of 39.6 kDa. The protein migrates as 45-65 kDa under reducing (R) condition (SDS-PAGE).

  • 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 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.

  • Background
    Influenza, commonly known as "the flu", is an infectious disease of birds and mammals caused by RNA viruses of the family Orthomyxoviridae, the influenza viruses. The virus is divided into three main types (Influenzavirus A, Influenzavirus B, and Influenzavirus C), which are distinguished by differences in two major internal proteins (hemagglutinin (HA) and neuraminidase (NA), which are the most important targets for the immune system. The type A viruses are the most virulent human pathogens among the three influenza types and cause the most severe disease. The serotypes that have been confirmed in humans, ordered by the number of known human pandemic deaths, are: H1N1, H2N2, H3N2, H5N1, H7N7, H1N2, H9N2, H7N2, H7N3, H10N7, H7N9. H7N9 is a serotype of the species Influenzavirus A (avian influenza virus or bird flu virus). H7 normally circulates amongst avian populations with some variants known to occasionally infect humans. An H7N9 virus was first reported to have infected humans in 2013 in China.
