Lead time: 3-7 working days

Research Topic: Microbiology

Uniprot ID: P03502

Gene Names: NS

Organism: Influenza B virus (strain B/Lee/1940)


Expression Region: 1-281aa

Sequence Info: Full Length

Source: E.coli

Tag Info: N-terminal 6xHis-tagged

MW: 36.1 kDa

Alternative Name(s): NS1A

Relevance: Binds and inhibits the conjugation of the ubiquitin-like G1P2/ISG15 protein to its target proteins. Since G1P2/ISG15 is an early antiviral protein, NS1 may inhibit the host antiviral response. Prevents EIF2AK2/PKR activation, either by binding double strand RNA or by interacting directly with EIF2AK2/PKR. Also binds poly(A) and U6 snRNA.

Purity: Greater than 85% as determined by SDS-PAGE.

Storage Buffer: Tris-based buffer,50% glycerol

Storage: The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20℃/-80℃. The shelf life of lyophilized form is 12 months at -20℃/-80℃.

Notes: Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
