Recombinant Tityus bahiensis Toxin Tb2-II

Recombinant Tityus bahiensis Toxin Tb2-II

• CAS Number: 9000-83-3
• UniProt: P60276
• Expression Region: 1-62aa
• Organism: Tityus bahiensis (Brazilian scorpion)
• Target Sequence: KEGYAMDHEGCKFSCFIRPSGFCDGYCKTHLKASSGYCAWPACYCYGVPSNIKVWDYATNKC
• Tag: N-terminal 10xHis-tagged and C-terminal Myc-tagged
• Source: E.coli
• Field of Research: Others
• Assay Type: In Stock Protein
• Relevance: Beta toxins bind voltage-independently at site-4 of sodium channels (Nav) and shift the voltage of activation toward more negative potentials thereby affecting sodium channel activation and promoting spontaneous and repetitive firing. This toxin is active against both mammals and insects.
• Purity: Greater than 85% as determined by SDS-PAGE.
• Activity: Not Test
• Length: Full Length
• 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 Conditions: 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℃.
