Human recombinant IFN alpha 2a (from E. coli)

Catalog Number: (PRSI91-018)
Supplier: ProSci Inc.
Supplier Article Number : 91-018
Description: At least 23 different variants of IFN- alpha are known. The individual proteins have molecular masses between 19-26 kDa and consist of proteins with lengths of 156-166 and 172 amino acids. All IFN- alpha subtypes possess a common conserved sequence region between amino acid positions 115-151 while the amino-terminal ends are variable. Many IFN- alpha subtypes only differ in their sequences by one or two positions. Naturally occurring variants also include proteins truncated by 10 amino acids at the carboxy-terminal end.

Human recombinant Angiopoietin-like 8 (from cells)

Catalog Number: (PRSI91-639)
Supplier: ProSci Inc.
Supplier Article Number : 91-639
Description: The protein specifically promotes pancreatic beta cell proliferation and beta cell mass expansion, thereby improving glucose tolerance. It promotes pancreatic beta cell proliferation without insulin resistance. Also it acts as a blood lipid regulator by regulating serum triglyceride levels and possibly by promoting ANGPTL3 cleavage. It interacts with ANGPTL3. It predominantly expressed in liver and also expressed in adipose tissues. The ability of the protein to induce pancreatic beta cell proliferation is promising in diabetes therapy. Betatrophin treatment could supply or replace insulin injections by increasing the number of insulin-producing cells in diabetes.

Human recombinant TNF alpha (from E. coli)

Catalog Number: (PRSI91-006)
Supplier: ProSci Inc.
Supplier Article Number : 91-006
Description: TNF alpha is a homotrimer with a subunit molecular mass of 17 kD and plays a major role in growth regulation, differentiation, inflammation, viral replication, tumorigenesis, autoimmune diseases and in viral, bacterial, fungal, and parasitic infections. Besides inducing hemorrhagic necrosis of tumors, TNF was found to be involved in tumorigenesis, tumor metastasis, viral replication, septic shock, fever, inflammation, and autoimmune diseases including Crohn’s disease, and rheumatoid arthritis as well as graft-versus-host disease.

Human recombinant EPO non-lytic (from CHO cells)

Catalog Number: (PRSI90-456)
Supplier: ProSci Inc.
Supplier Article Number : 90-456
Description: Erythropoietin is the principal hormone involved in the regulation of erythropoiesis by stimulating the proliferation and differentiation of erythroid progenitor cells and the maintenance of a physiological level of circulating erythrocyte mass. It is a glycoprotein produced primarily by the kidney. The biological effects of EPO are mediated by the erythropoietin receptor (Epo R). Genetic variations in EPO is associated with susceptibility to microvascular complications of diabetes type 2 (MVCD2) (including diabetic retinopathy, diabetic nephropathy leading to end-stage renal disease and diabetic neuropathy). It is used for the treatment of anemia and misused as a performance-enhancing drug in endurance athletes.

Human recombinant Lepr (from HEK293 cells)

Catalog Number: (PRSI96-513)
Supplier: ProSci Inc.
Supplier Article Number : 96-513
Description: Leptin receptor (LEPR) is also known as LEP-R, cluster of differentiation 295 (CD295), OB-R and B219, is a single-transmembrane-domain receptor of the gp130 family of cytokine receptors. Leptin receptor exists as homodimer and binds Leptin with high affinity, thus mediates the biological function of the adipocyte-specific hormone Leptin. LEPR is a receptor for leptin (an adipocyte-specific hormone that regulates body weight), and is involved in the regulation of fat metabolism, as well as in a novel hematopoietic pathway that is required for normal lymphopoiesis. Mutations in this protein have been associated with obesity and pituitary dysfunction. Interaction of leptin and leptin receptor is crucial for body weight and bone mass regulation in mammals through hypothalamic effects on satiety and energy expenditure. Meanwhile, research data supports a leptin receptor activation model based on ligand-induced conformational changes.
