• Protein Length: Full Length of Mature Protein
• Source: E.coli
• Biological Origin: Streptococcus pyogenes serotype M28 (strain MGAS6180)
• Expression Region: 146-398aa
• Endotoxins: Not test.
• 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℃.
• Buffer/Preservatives: 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.
• Alternative names: Exotoxin type B SPE B Streptococcal cysteine prote
• Note: For research use only
• Application notes: This is His-SUMO-tag protein
• Expiration Date: 6 months from date of receipt.

(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.

Based on the SEQUEST from database of E.coli host and target protein, the LC-MS/MS Analysis result could indicate that this peptide derived from E.coli-expressed Streptococcus pyogenes serotype M28 (strain MGAS6180) speB.
