Specifications

• Source:
  E. coli
• Species:
  Human
• Storage conditions:
  Lyophilized Interleukin-8 although stable at room temperature for weeks, should be stored desiccated below −18 °C. Upon reconstitution CXCL8 should be stored at 4 °C between 2-7 days and for future use below −18 °C. For long term storage it is recommended to add carrier protein (0. 1% HSA or BSA). Please prevent freeze/thaw cycles.
• Biological activity:
  Specific Activity of IL8 in chemotaxis of donor PBL neutrophils, threshold concentration corresponding to 10-100 ng/ml.
• Protein synonyms:
  310C
• Protein/peptide name:
  IL8
• Purity:
  Greater than 98.0% as determined by RP-HPLC and analysis by SDS-PAGE
• Solubility:
  It is recommended to reconstitute the lyophilized Interleukin-8 in sterile H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
• Sequence:
  The sequence of the first five N-terminal amino acids was determined and was found to be Ser-Ala-Lys-Glu-Leu.
• Formulation:
  The IL-8 was lyophilized from concentrated (1mg/ml) solution in water containing no additives.
• Tested applications:
  SDS-PAGE
