Product Overview

Abbreviation
Recombinant E.coli O157:H7 sspB protein
Alternative names
sspB; Z4586; ECs4101Stringent starvation protein B
Buffer [rich text]
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.
Endotoxin
Not test
Expression region
1-165aa
Form
Liquid or Lyophilized powder
Function
Seems to act in concert with SspA in the regulation of several proteins during exponential and stationary-phase growth. The exact function of SspB is not yet known (By similarity).
Gene names
sspB
Mw
22.3 kDa
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4℃ for up to one week.
Organism
Escherichia coli O157:H7
Protein length
Full Length
Purity
Greater than 85% as determined by SDS-PAGE.
Reconstitution [rich text]
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℃.
