Recombinant Influenza B (B/Florida/4/2006) HA Protein, Fc-tagged

• Cat.No.: HA-279V
• Product Overview: Recombinant C-terminal fragment (Gly 362-Ala 555) of influenza B virus (B/Florida/4/2006) (ACA33493.1) hemagglutinin, termed as HA2, was fused with the Fc region of human IgG1 at the N-terminus.

Specification

• Source: HEK293
• Species: Influenza B
• Tag: Fc
• Predicted N Terminal: Glu
• Form: Lyophilized from sterile PBS, pH 7.4, 5%~8% trehalose and mannitol.
• Molecular Mass: The recombinant Influenza B virus (B/Florida/4/2006) HA2/Fc is a disulfide-linked homodimeric protein. The reduced monomer comprises 452 amino acids with the predicted molecular mass of 49.3 kDa. As a result of glycosylation, it migrates as an approximately 60 kDa band in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: >95 % as determined by SDS-PAGE.
• Stability: Samples are stable for up to twelve months from date of receipt at -70ºC.
• Storage: Store it under sterile conditions at -20ºC~-70ºC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.25 ug/ul. Centrifuge the vial at 4℃ before opening to recover the entire contents.
