Recombinant Human IL-6

General description

Interleukin-6 is a pleiotropic cytokine with both pro-inflammatory and anti-inflammatory properties, regulating acute phase responses, B cell differentiation, and Th17 cell development. It is a critical mediator of cytokine release syndrome and a therapeutic target in autoimmune diseases and cancer. Recombinant Human IL-6 Protein (Y02301) is expressed from mammalian cells. It contains AA Val 30-Met 212 (Accession # P05231), and is widely used in advanced cell culture, immunology research, and inflammation modeling.

Application

• B Cell Differentiation and Antibody Production — Drives plasma cell differentiation and immunoglobulin secretion.

• Th17 Cell Polarization — Promotes IL-17-producing T cell development in combination with TGF-β.

• Acute Phase Response Modeling — Induces hepatocyte production of CRP, fibrinogen, and serum amyloid A.

• Cytokine Release Syndrome Research — Models IL-6-driven systemic inflammation and therapeutic intervention.

• Serum-Free Culture Systems — Suitable for chemically defined and xeno-free cell culture media.

Backgroud

Interleukin 6 (IL-6) is also known as HGF, BSF2,HSF, IFNB2 and IL-6, originally identified as a B cell differentiation factor, is a multifunctional cytokine that regulates immune responses, hematopoiesis, acute phase responses, and inflammatory reactions.It is secreted by T cells, macrophages , monocytes, fibroblasts,endothelial cells,et.al. to stimulate immune response to trauma, especially burns or other tissue damage leading to inflammation. Interleukin 6 has been shown to interact with interleukin-6 receptor and glycoprotein. IL-6 is relevant to many disease processes such as diabetes,atherosclerosis, depression,Alzheimer's Disease,systemic,lupus erythematosus,prostate cancer and rheumatoid arthritis. Advanced/metastatic cancer patients have higher levels of IL-6 in their blood.Hence there is an interest in developing anti-IL-6 agents as therapy against many of these diseases.

Q&A

IL-6 is primarily used for B cell differentiation, Th17 polarization, acute phase response modeling, and cytokine release syndrome research.

Q2: Is this IL-6 suitable for serum-free culture systems?

Yes. EastMabBio recombinant IL-6 is compatible with serum-free, xeno-free, and chemically defined media systems.

Q3: How should recombinant IL-5 be stored?

Lyophilized protein should be stored at -20°C or below. After reconstitution, aliquot and avoid repeated freeze-thaw cycles.

Q4: What shipping conditions are used?

Products are shipped on dry ice with validated cold-chain packaging to maintain stability during international transportation.

Q5: Do you provide QC documents?

Yes. COA, MSDS, TSE-BSE statements, endotoxin reports, bioactivity data, and additional QC documentation are available upon request.
