Description

General description

IFN-α1 (interferon α 1) is a type 1 interferon. Human IFN-a1 is a 19.3kDa protein containing 166 amino acid residues.

Biochem/physiol Actions

IFN-α1 (interferon α 1) is a lymphoid factor that possesses potent anti-viral activity. IFN-α1 interacts with IFNAR1 (interferon α receptor 1) and IFNAR2. The interaction activates JAK1 (janus-activated kinase 1) and tyrosine kinase 2. These events phosphorylate and activate STAT1 and STAT2 (signal transducer and activator of transcription proteins), leading to the upregulation of interferon-stimulated genes some of which encode antiviral proteins.

Physical form

Lyophilized without any additives.

Reconstitution

Centrifuge the vial prior to opening. Avoid freeze-thaw cycles.

Reconstitute in water to a concentration of 0.1-1 mg/mL. This solution can then be diluted into other aqueous buffers.
