Scientific Background
Binds to the N-acetyl-9-O-acetylneuraminic acid residues on the cell surface, bringing about the attachment of the virus particle to the cell. Plays a major role in the determination of host range restriction and virulence. Class I viral fusion protein.
Product Description
Yeast (S. cerevisiae) ExpressionRecombinant Influenza C virus Hemagglutinin-esterase-fusion glycoprotein (HE), partial is a recombinant protein expressed in Yeast (S. cerevisiae) and purified to Greater than 90% as determined by SDS-PAGE. as determined by SDS-PAGE. Supplied as Liquid or Lyophilized powder, n-terminal 6xhis-tagged. For research use only.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
