IFNW1 Protein Product Information
A DNA sequence encoding the human IFNW1 (P05000) (Met1-Ser195) was expressed with a polyhistidine tag at the C-terminus.
|Expression Host:||Human Cells|
IFNW1 Protein QC Testing
|Purity:||> 95% as determined by SDS-PAGE||SDS-PAGE:
|Measured in antiviral assays using WISH human amnion cells infected with vesicular stomatitis virus(VSV).
The ED50 for this effect is typically 2-8 pg/mL.
|Endotoxin:||< 1.0 EU per μg of the protein as determined by the LAL method|
|Stability:||Samples are stable for up to twelve months from date of receipt at -70℃|
|Predicted N terminal:||Leu 22|
The recombinant human IFNW1 consists of 185 amino acids and predicts a molecular mass of 21.6 KDa. It migrates as an approximately 22 KDa band in SDS-PAGE under reducing conditions.
|Formulation:||Lyophilized from sterile PBS, pH 7.4.

IFNW1 Protein Description
IFNs are a large family of proteins having antiviral, antiproliferative, and immunomodulatory effects, and are divided into two major classes, type I and type I I, on the basis of differences in receptor binding and nucleotide sequence. Type I IFNs consist of IFN α, β, τ, and ω and bind to the type I IFN receptor, whereas IFN-γ is the only type I I IFN and is specific for the type I I IFN receptor. Human IFN-ω, was identified by three independent groups in 1985 and is structurally related to IFN-α and -β. Both human IFN-ω and IFN-α are produced by virally induced leukocytes and have similar antiviral activities on human cell lines, and a sizeable proportion (at least 10%) of the total antiviral activity of leukocyte IFN is contributed by IFN-ωl. In addition, it was reported that IFN-ω could inhibit the growth of human tumors in vivo.
