5-10 business days
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.

Description
Interferon alpha-1/13 plays a central role in antiviral innate immunity and immunomodulation, making validated signaling potency essential for meaningful experimental outcomes. This tag-free recombinant human IFNA1, encompassing the full mature sequence (aa 24–189) expressed in *E. coli*, delivers a specific activity of no less than 1.0 × 10⁸ IU/mg in anti-viral assays, confirming robust biological function suitable for JAK/STAT signaling pathway dissection, PBMC activation studies, and use as a reference standard in interferon detection assays. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that would otherwise confound cytokine-driven responses in sensitive immune cell functional assays or in vivo models of infection and tumor biology. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, supports use as a coating antigen or positive control in ELISA-based antibody validation workflows.
