Description : Interleukin 28B (IL-28B) predicts a molecular mass of 19.7 kDa. IL-28 comes in two isoforms, IL-28A and IL-28B, and plays a role in immune defense against viruses, including the induction of an "antiviral state" by turning on Mx proteins, 2',5'-oligoadenylate synthetase as well as ISGF3G.
Source : E. coli
Species : Mouse
Tag : His
Form : Lyophilized
Bio-activity : Measure by its ability to protect HepG2 cells infected with encephalomyocarditis (EMC) virus. The ED50 for this effect is < 20 ng/mL.
Molecular Mass : The protein has a calculated MW of 20.56 kDa.
The protein migrates as 17-25 kDa under reducing condition (SDS-PAGE analysis).
Protein length : Asp20-Val193
Endotoxin : < 0.1 EU/μg of the protein by the LAL method.
Purity : >98% as determined by SDS-PAGE analysis.
Storage : This product is stable after storage at:
-20 centigrade for 12 months in lyophilized state from date of receipt.
-20 or -80 centigrade for 2 weeks under sterile conditions after reconstitution.
Avoid repeated freeze/thaw cycles.
Storage Buffer : Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
Reconstitution : It is recommended to reconstitute the lyophilized protein in sterile H2O to a concentration not less than 200 μg/mL and incubate the stock solution for at least 20 min to ensure sufficient re-dissolved.
Shipping : The product is shipped with polar packs. Upon receipt, store it immediately at -20 centigrade or lower for long term storage.

        Ask a question
        IL28B has made a breakthrough in treating what diseases? 04/18/2022

        IL28B has achieved remarkable results in the treatment of hepatitis C. The study found that patients with a specific genotype, which is related to IL28B, were better able to benefit from treatment with the hepatitis drug interferon. Therefore, the combination of IL28B with other drugs can improve the efficacy.

        What is the mechanism of action of IL28B? 06/11/2021

        IL28B can regulate the immune response of cells and promote the occurrence of insulin-dependent cytotoxicity mediated by NK cells, thus playing an antiviral role.

        IL28B purification ofs have? 05/19/2021

        The purification methods of IL28B include ion exchange, gel filtration, affinity chromatography, countercurrent chromatography, etc.

        How many therapeutic doses of IL28B are usually used? 08/08/2020

        The dose of treatment with IL28B varies depending on the patient. When treating hepatitis C, the dose is usually given once a week, 500ug or another dose.

        What are the adverse reactions of IL28B? 07/15/2020

        The adverse reactions of IL28B include fever, headache, fatigue, muscle aches, nausea, diarrhea and other symptoms, and in severe cases, allergic reactions and liver damage.

        Does IL28B affect the function of other organs in the body? 01/10/2019

        IL28B will have a certain impact on the function of other organs of the body, such as the liver, kidneys, etc., but the use of normal doses in clinical practice is generally safe.
