Influenza A, Hong Kong 1079/99 (H9), Hemagglutinin, Recombinant

Recombinant HA-H9N2 Hong Kong 1073/99 is glycosylated with N-linked sugars, produced using baculovirus vectors in insect cells. H9N2 is a subtype of the species Influenza A virus, whereas the PB1 and PB2 genes are closely related to those of the H5N1viruses and a quailH9N2 virus A/quail/Hong Kong/G1/97 (Qa/HK/G1/97) suggesting that many of the 1997chicken H9 isolates in the markets were reassortants. Molecular Weight: 72kD Accession number: AJ404626, Immunological Activity: Western-Blot 0.1ug/ug per strip, ELISA 1ug/well, Dimers and Aggregates: , < 1% as determined by silver-stained SDS-PAGE gel analysis. Endotoxin: < 0.1ng/ug (IEU/ug) of Recombinant HA. Stability: Recombinant HA although stable at 15°C for 2-4 weeks, should be stored at 4°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please avoid freeze-thaw cycles.
