• Tag: N-terminal 10xHis-tagged and C-terminal Myc-tagged
• Source: E.coli
• Field of Research: Others
• Assay Type: In Stock Protein
• Relevance: The S-layer is a paracrystalline mono-layered assembly of proteins which coats the surface of bacteria. This protein is critical for virulence.
• Purity: Greater than 85% as determined by SDS-PAGE.
• Activity: Not Test
• Length: Partial
• 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.
