Influenza A H5N1 (A/VietNam/1203/2004) Hemagglutinin / HA Protein (His & Fc Tag)

HA

• 100ug (NPP1420) Please inquiry

Catalog Number	P10003-V06H3
Organism Species	H5N1
Host	Human Cells
Synonyms	HA
Molecular Weight	Recombinant HA/mFc is a disulfide-linked homodimeric protein. The reduced monomer consisting of 754 amino acids has a calculated molecular mass of 85.7 kDa. As a result of glycosylation, the HA/mFc monomer migrates as an approximately 110-120 kDa protein in SDS-PAGE under reducing conditions.
predicted N	Asp 17
SDS-PAGE
Purity	> 90 % as determined by SDS-PAGE
Protein Construction	A DNA sequence encoding the extracellular domain of hemagglutinin (Influenza A virus (A/Viet Nam/1203/2004 (H5N1)) (AAW80717.1) (Met 1-Gln 531) with cleavage site mutated (RERRRKKR→TETR,HA1+HA2,uncleaved) was fused with the C-terminal polyhistidine-tagged Fc region of mouse IgG1 at the C-terminus.
Bio-activity
Research Area	Microbiology |Pathogenic microorganism |viruses |animal virus |viral illness |Viral tract respiratory illness |
Formulation	Lyophilized from sterile 100mM NaAc, 10mM NaCl, 200mM Tris, pH 7.5 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
