Recombinant Escherichia coli Heat-stable enterotoxin A2 (sta2) | CSB-EP670621ENL | Cusabio

Alternative Name(s): STA2

Gene Names: sta2

Research Areas: Others

Organism: Escherichia coli


Source: E.coli

Tag Info: N-terminal 10xHis-SUMO-tagged and C-terminal Myc-tagged

Expression Region: 54-72aa

Sequence Info: Full Length of Mature Protein

MW: 18.1 kDa

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

Relevance: Toxin which activates the particulate form of guanylate cyclase and increases cyclic GMP levels within the host intestinal epithelial cells.

Reference: "Rectification of two Escherichia coli heat-stable enterotoxin allele sequences and lack of biological effect of changing the carboxy-terminal tyrosine to histidine." Guzman-Verduzio L.M., Kupersztoch Y.M. Infect. Immun. 57:645-648(1989)

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.

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.
