Specifications

• Source:
  E. coli
• Species:
  Human
• 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:
  Periostin
• Purity:
  Greater than 90% as determined by SDS-PAGE. Three-step procedure using affinity Ni-NTA chromatography and size exclusion chromatography before and after refolding.
• Solubility:
  Add 0.2 uml of 0.1M Acetate buffer pH4 and let the lyophilized pellet dissolve completely. For conversion into higher pH value, we recommend intensive dilution by relevant buffer to concentration of 10ug/ml. In higher concentrations the solubility of this
• Formulation:
  Sterile filtered and lyophilized from 0.5 mg/ml in 0.05M Acetate buffer pH-4.
• Tested applications:
  SDS-PAGE
