Uniprot ID: P69179

Gene Names: stxB

Organism: Enterobacteria phage H19B (Bacteriophage H19B)

AA Sequence: TPDCVTGKVEYTKYNDDDTFTVKVGDKELFTNRWNLQSLLLSAQITGMTVTIKTNACHNGGGFSEVIFR

Expression Region: 21-89aa

Sequence Info: Full Length of Mature Protein

Source: E.coli

Tag Info: N-terminal 6xHis-tagged

MW: 11.7 kDa

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.
