Active Recombinant Influenza A H9N2 (A/Guinea fowl/Hong Kong/WF10/99) HA Protein, His & Avi-tagged, Biotinylated

Cat.No. : HA-347I
Product Overview : Recombinant Influenza A H9N2 (A/Guinea fowl/Hong Kong/WF10/99) HA Protein, His & Avi-tagged, Biotinylated is expressed from human 293 cells (HEK293). It contains AA Asp 19 - Lys 523 (Accession # AAO46082.1). Predicted N-terminus: Asp 19. This protein carries an Avi tag at the C-terminus, followed by a polyhistidine tag. The protein has a calculated MW of 60 kDa. The protein migrates as 66-70 kDa under reducing (R) condition (SDS-PAGE). The biotin to protein ratio is 0.5-1 as determined by the HABA assay.

Q&As (6)

Ask a question
How about the structural characteristics of HA protein? 09/14/2019

HA protein is a glycoprotein that contains thousands of carbohydrates and an amino acid chain consisting of 566 amino acid residues. The structure of HA protein has triple symmetry, consisting of three monomers that form a spiral.

Will genetic variants in HA proteins affect vaccine development? 06/06/2019

Genetic variants in the HA protein may affect the development and production of influenza vaccines. Because HA protein is an important component of influenza viruses, different subtypes or variants of HA protein may require different vaccines to prepare.

Why is hemagglutinin protein related to viral replication? 05/17/2019

This protein is one of the key factors in the replication process of influenza viruses. When a virus infects a host cell, the receptor-binding region of the HA protein binds to the receptor on the cell surface, allowing the virus to invade the host cell and replicate.

What are the subtypes of HA protein? 04/01/2019

There are currently 18 known HA subtypes of influenza viruses, H1-H18. Among them, the H1, H2, H3, H5, H7, and H9 subtypes are associated with human viruses, while other subtypes are generally associated with animal viruses.

What are the physiological functions of HA protein? 03/07/2019

The main physiological function of HA protein is to bind to host cells and mediate the entry of influenza viruses into host cells. It contains specific regions that bind glycoprotein receptors that allow the influenza virus to adhere to them. This is an important link that allows the virus to stably bind and enter the cell.

What laboratory techniques are HA proteins used in? 01/07/2019

HA protein is widely used in viral research and drug development. Researchers can use HA proteins to test drugs such as influenza virus activators, antibodies and vaccines, and HA proteins are also widely used to develop novel immunoassays and treatments.

    The transport process does not affect the protein quality, and the stability is good.

    11/27/2019

      Higher solubility makes it easy to prepare the desired concentration.
