Specifications

• Source:
  E. coli
• Storage conditions:
  Store lyophilized protein at −20 °C. Aliquot the product after reconstitution to avoid repeated freezing/thawing cycles. Reconstituted protein can be stored at 4 °C for limited period of time; it does not show any change after two weeks at 4 °C.The lyophilized protein remains stable until the expiry date when stored at −20 °C.
• Protein/peptide name:
  HBV X
• Purity:
  Greater than 95% as determined by SDS-PAGE. Two-step procedure using size exclusion chromatography before and after refolding.
• Solubility:
  Add 0.1M Acetate buffer pH4 to prepare working stock solution of approximately 0.5 mg/ml and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to concentration of 10ug/m
• Formulation:
  Sterile filtered and lyophilized from 0.5 mg/ml in 0.05M Acetate buffer pH4.
• Tested applications:
  SDS-PAGE
