Research Areas:Signal Transduction
Uniprot ID:Q32GM0
Gene Names:stxB
Organism:Shigella dysenteriae serotype 1 (strain Sd197)
AA Sequence:TPDCVTGKVEYTKYNDDDTFTVKVGDKELFTNRWNLQSLLLSAQITGMTVTIKTNACHNGGGFSEVIFR
Expression Region:21-89aa
Sequence Info:Full Length of Mature Protein
Source:E.coli
Tag Info:N-terminal 10xHis-tagged and C-terminal Myc-tagged
MW:15.1 kDa
Alternative Name(s):stxB; SDY_1390; Shiga toxin subunit B
Relevance:The B subunit is responsible for the binding of the holotoxin to specific receptors on the target cell surface, such as globotriaosylceramide in human intestinal microvilli.

Purity:Greater than 85% as determined by SDS-PAGE.
Form:Liquid or Lyophilized powder
Buffer:If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution:We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20?/-80?. Our default final concentration of glycerol is 50%. Customers could use it as reference.
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.
Function:The B subunit is responsible for the binding of the holotoxin to specific receptors on the target cell surface, such as globotriaosylceramide (Gb3) in human intestinal microvilli.
