    Endotoxin level

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

  • Form

    Lyophilized

• Background

  • Background

    Interferon Beta 1a (IFN beta 1a) is a leukocyte interferon,
    which is a variant of Interferon beta. IFN beta 1a is a
    17.87 kDa protein containing 161 amino acid residues. It could bind the interferon receptors that activates the signal transduction of immune responses through the Jak/STAT pathway in leukocytes and lymphoblastoid cells.

    Synonyms

    Interferon beta, IFN-beta
