Human IL-6 Protein, premium grade

GMP Version Available: GMP Human IL-6 Protein   

分子别名(Synonym)

IL6,Interleukin-6,BSF2,HSF,IFNB2

表达区间及表达系统(Source)

Human IL-6, premium grade (IL6-H4218) is expressed from human 293 cells (HEK293). It contains AA Val 30 - Met 212 (Accession # NP_000591.1).

Predicted N-terminus: Val 30

Human IL-6, premium grade (IL6-H4218), designed for preclinical stage, has the same activity and performance with GMP Human IL-6 (GMP-L06H27), which enables a seamless transition from preclinical development to clinical phases. Premium Grade product offer a cost efficient alternative of GMP Grade products for the early development phase when safety of raw materials is not top priority. By using Premium Grade products in early development phase, you can transition easily into clinical and commercial phase without need to revalidate the raw materials and modify manufacturing process.

背景(Background)

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.
