Target INTERLEUKIN-28A

Recombinant Human Interleukin-28A, His Tag is supplied as a recombinant protein for in vitro research use.

Background

IL-28A is distantly related to type I interferons and the IL-10 family. Expression of IL-28A is induced by viral infection which interacts with a heterodimeric class II cytokine receptor that consists of interleukin 10 receptor, beta (IL10RB) and interleukin 28 receptor, alpha. IL-28A exhibits common features with type I IFNs such as antiviral activity, antiproliferative activity and in vivo antitumour activity. IL-28A acts similarly to IFNs, but is less effective generally and has activity in a more limited range of cell lines. IFN-ambda 1, IFN-lambda 2 and IFN-lambda 3 are closely positioned genes on human chromosome
19. IL-28A induces ELR(-) CXC chemokine mRNA in human peripheral blood mononuclear cells, in an IFN-gamma-independent manner. IL-28A is able to generate tolerogenic DCs, an activity that could thwart IFN-beta functions. IL-28A produced in response to viral infection, activates both monocytes and macrophages producing a restricted panel of cytokines and therefore is an important factor in activating innate immune responses at the site of viral infection.

Product format

Provided as a recombinant protein suitable for in vitro workflows such as binding studies, screening, and assay development. Refer to the specifications table for expression format and molecular properties.

What is the purity of Recombinant Human Interleukin-28A, His Tag (Human)?
Greater than 85% as determined by SDS-PAGE. BioHippo includes a Certificate of Analysis (CoA) confirming purity per lot with every order.
What buffer / formulation is this protein supplied in?
Supplied as: IL 28A protein solution (0.5mg/ml) contains 20mM Tris-HCl buffer (pH 8.0), 10% glycerol and 0.4M Urea. Reconstitute lyophilized material in sterile ultrapure water or the recommended buffer per the datasheet prior to use.
How should Recombinant Human Interleukin-28A, His Tag (Human) be stored?
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles. Prepare single-use aliquots after reconstitution to avoid repeated freeze–thaw cycles.
What expression system was used to produce this protein?
This recombinant protein was expressed in E. coli. The system was selected to achieve high yield, correct folding, and appropriate post-translational modifications.
Is this protein approved for clinical or in vitro diagnostic use?
No. Supplied for Research Use Only (RUO) — not intended for therapeutic applications or in vitro diagnostic procedures.
Can I request a custom size, tag variant, or formulation?
Yes. BioHippo can accommodate custom requests including alternative sizes, His/GST/Fc tag variants, bulk quantities, and custom formulations. See the Customization & Add-ons tab or email support@biohippo.com.
