Cat. No. : IL28B-600H
Description : IL28 is a cytokinethat comes in two isoforms, IL28A and IL28B, and plays a role in immunedefense against viruses, including the induction an antiviral state byturning on Mx proteins, 2",5"-oligoadenylate synthetase as well as ISGF3G(Interferon Stimulated Gene Factor 3). IL28A and IL28B belong to the type IIIinterferon family of cytokines and are highly similar (in amino acidsequence) to IL-29.

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.
