• Protein synonyms:
  Leukocyte interferon
• Protein/peptide name:
  INF beta 1a
• Purity:
  Greater than 98.0% as determined by(a) Analysis by RP-HPLC. (b) Analysis by SDS-PAGE.
• Solubility:
  It is recommended to reconstitute the lyophilized Interferon beta 1a in sterile H2O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
