      Endotoxin level

      <0.1 EU per 1 μg of the protein by the LAL method.

    • Form

      Lyophilized

  • Background
    • Background

      Activin is the member of the TGF beta superfamily of cytokines. The current understanding of Activin A is classified as a hormone, a Growth Factors, and a cytokine. Depending on the different cell type, that overexpression of Activin A can either inhibit or promote cells division. There are important implications for tumor biology. Activin A also increase joint inflammation in rheumatoid arthritis (RA) and induces pathogenic mechanisms in the respiratory system.

      Synonyms

      INHBA, Inhibin beta A, FSH releasing protein.

  • Instruction
    • Reconstitution

      It is recommended to reconstitute the lyophilized protein in sterile H₂O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.

      Shipping

      The product is shipped with polar packs. Upon receipt, store it immediately at -20°C or lower for long term storage.

    • Stability & Storage

      This product is stable after storage at:
      ● -20°C for 12 months in lyophilized state from date of receipt.
      ● -20°C or -80°C for 1 month under sterile conditions after reconstitution.
      Avoid repeated freeze/thaw cycles.
