Opis

Opis ogólny

The gene for visfatin (also known as pre-B colony enhancing factor 1, PBEF1, nicotinamide phosphoribosyl transferase, NAMPT), is mapped to human chromosome 7q22.3. The encoded protein is an adipokine produced from adipocytes. It is a highly conserved protein and is also secreted by lymphocytes. Visfatin is expressed in large amounts in the bone marrow, liver tissue, and muscle and is also present in heart, placenta, lung, and kidney tissues.

Specyficzność

Anti-Visfatin (C- terminal) recognizes human and rat visfatin.

Zastosowanie

Anti-Visfatin (C-terminal) antibody produced in rabbit has been used in:

• western blotting(10)
• immunohistochemistry
• immunofluorescence

Działania biochem./fizjol.

Visfatin is an enzyme that catalyzes the biosynthesis of nicotinamide adeninine dinucleotide (NAD) from nicotinamide. A variety of signaling pathways are regulated by visfatin including phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT), signal transducer and activator of transcription 3 (STAT3) and extracellular signal-regulated protein kinase (ERK1/2). It is also reported to regulate the activity of sirtuin 1 (SIRT1) and protect the mammalian cells from death. Since visfatin catalyses a major rate-limiting step in the production of NAD, it is crucial in metabolism, carcinogenesis and immune responses. Visfatin also can act as cytokine and regulates the expression of vascular endothelial growth factor (VEGF) in the proliferation of endothelial cells and formation of capillary tubes. Deregulation of visfatin has been implicated in diabetes mellitus, obesity, rheumatoid arthritis and chronic hepatitis

Visfatin is involved in the regulation of energy homeostasis. Visfatin has been shown to activate its target cells by binding to the insulin receptor at a site distinct from insulin, and its expression level in plasma increases during the development of obesity. Visfatin can induce the cellular expression of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-7,(11) and IL-6.

Postać fizyczna

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.

Przechowywanie i stabilność

For continuous use, store at 2–8 °C for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing, or storage in “frost-free” freezers, is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.
