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. IFN-α1 belongs to the type I interferon (IFN) family and is present in leukocytes. The IFN-α1 gene is mapped to human chromosome 9p21.3.

Application

IFN-alpha 1 human has been used:
  • to treat Vero and breast cancer (MDA-MB-231) cells in interferon assay before viral infection
  • as a ligand to vaccinia virus B18R protein in analytical size exclusion chromatography
  • to treat chikungunya infected human embryonic kidney cell line (HEK293T) to test its effect on Signal transducer and activator of transcription 1 (STAT1) phosphorylation
  • as recombinant interferon to treat lung fibroblast cell line (IMR90) to monitor histone chaperone (HIRA) response

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. IFN-alpha 1 (IFN-α1) mediates apoptosis in specific tissues. It may be useful in treating laryngeal carcinoma. The interaction of microRNA, miR-181b with IFN-α1, is regarded as a risk factor in systemic lupus erythematosus.

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.

Glioblastomas (GBMs) are deadly tumors of the central nervous system. Most GBM exhibit homozygous deletions of the CDKN2A and CDKN2B tumor suppressors at 9p21.3, although loss of CDKN2A/B alone is insufficient to drive gliomagenesis. MIR31HG, which encodes microRNA-31 (miR-31), is
