胰岛素,Insulin, Human Recombinant

产品描述

Biochem/physiol Actions

Two-chain polypeptide hormone produced by the β-cells of pancreatic islets. Its molecular weight is ~5800 Da. The α and β chains are joined by two interchain disulfide bonds. The α chain contains an intrachain disulfide bond. Insulin regulates the cellular uptake, utilization, and storage of glucose, amino acids, and fatty acids and inhibits the breakdown of glycogen, protein, and fat.

Application

Serum-free medium supplements such as insulin are essential for long-term growth of commonly used mammalian cell lines. When insulin is absent from media, cell may exhibit disturbances in morphology and growth rate.
• Recombinant Human Insulin has been used in the media for adipogenic induction of mesenchymal stem cells.[1]
• It has been used as a supplement in the cell culture media of airway epithelial cells.[3]
• It has been used in the culture media for differentiation of cells, GLUT4 (glucose transporter type 4) translocation assay and to study interaction of insulin with insulin receptor via surface plasmon resonance.[2]

General description

Insulin, recombinant human (rHu) is identical in function and structure to the native human sequence. A hormone consisting of two polypeptide chains, rHu Insulin′s A-chain (21 amino acids) and B-chain (30 amino acids) are covalently linked by disulfide bonds between cysteine residues. This genetically engineered human insulin is a full sequence molecule producted by recombinant DNA technology in baker′s yeast.

Recombinant Human IFN-β

产品编号:

AF-300-02B
别名:
Leukocyte interferon, B cell interferon, Type I interferon
描述:
Proteins of this family play an important role in inducing non-specific resistance against a broad range of viral infections. They also affect cell proliferation and modulate immune responses. Produced by peripheral blood leukocytes and lymphoblastoid cells, IFNα is an acid stable molecule that signals through IFNα/βR, which is also used by IFNβ. Both IFNs have similar anti-viral activity and regulate expression of MHC class I antigens. IFNα contains four highly conserved cysteine residues which form two disulfide bonds, one of which is necessary for biological activity. Recombinant human IFNβ is an 20.0 kDa protein containing 166 amino acid residues. Manufactured using all non-animal reagents.

纯度:
Greater than 95% by SDS-PAGE gel and HPLC analyses.
生物活性:
Determined by its ability to stimulate the proliferation of human TF-1 cells. The expected ED50 is ≤ 0.25 ng/ml, corresponding to a specific activity of ≥ 4 x 106 units/mg.
