Biological Activity
The ED50 as determined by an anti-viral assay using human HepG2 cells infected with encephalomyocarditis is less than 30 ng/ml, corresponding to a specific activity of > 3.3 × 104 IU/mg.
Reconstitution
It is recommended to reconstitute the lyophilized IL-28B in sterile water not less than 100ug/ml, which can then be further diluted to other aqueous solutions.
Preparation and Storage
Although stable at room temperature for 3 weeks, should be stored desiccated below -18 degree C.
Related Product Information for IL-28B active protein
IL-28B is a cytokine remotely related to type I interferons and the IL-10 family. Interleukin-28B, interleukin 28A (IL28A), and interleukin 29 (IL29) are 3 closely related cytokine genes which form a cytokine gene cluster on a chromosomal region mapped to 19q13. Expression of the cytokines encoded by these 3 genes can be induced by viral infection. All 3 cytokines interact with a heterodimeric class II cytokine receptor which consists of interleukin 10 receptor, beta (IL10RB) and interleukin 28 receptor, alpha (IL28RA).

Uniprot Description

Cytokine with antiviral, antitumour and immunomodulatory activities. Plays a critical role in the antiviral host defense, predominantly in the epithelial tissues. Acts as a ligand for the heterodimeric class II cytokine receptor composed of IL10RB and IFNLR1, and receptor engagement leads to the activation of the JAK/STAT signaling pathway resulting in the expression of IFN-stimulated genes (ISG), which mediate the antiviral state. Has a restricted receptor distribution and therefore restricted targets: is primarily active in epithelial cells and this cell type-selective action is because of the epithelial cell-specific expression of its receptor IFNLR1. Seems not to be essential for early virus-activated host defense in vaginal infection, but plays an important role in Toll-like receptor (TLR)-induced antiviral defense. Plays a significant role in the antiviral immune defense in the intestinal epithelium. Exerts an immunomodulatory effect by up-regulating MHC class I antigen expression.

Product Notes

The IL-28B ifnl3 (Catalog #AAA692522) is an Active Protein produced from E Coli and is intended for research purposes only. The product is available for immediate purchase. The amino acid sequence is listed below: DPVPRATRLP VEAKDCHIAQ FKSLSPKELQ AFKKAKGAIE KRLLEK DMRC SSHLISRAWD LKQLQVQERP KALQAEVALT LKVWENINDS A LTTILGQPL HTLSHIHSQL QTCTQLQATA EPKPPSRRLS RWLHRLQ EAQ SKETPGCLED SVTSNLFQLL LRDLKCVASG DQCV. It is sometimes possible for the material contained within the vial of "IL-28B, Active Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
