小鼠瘦蛋白ELISA试剂盒描述:
Leptin (or obese, OB) is a circulating hormone that is expressed abundantly and specifically in the adipose tissue. Mouse ob protein is a 166-amino acid polypeptide with a putative signal sequence and is 84 and 83% homologous to the mouse and rat ob proteins, respectively. Northern blot analysis reveals that OB RNA is present at a high level in adipose tissue but at much lower levels in placenta and heart. Indeed, Leptin is first described as an adipocyte-derived signalling factor, which, after interaction with its receptors, induces a complex response including control of bodyweight and energy expenditure. Leptin seems in addition to its role in metabolic control to have important roles in reproduction and neuroendocrine signalling. Leptin is a powerful inhibitor of bone formation in vivo. Comparative mapping of mouse and mouse DNA indicates that the ob gene is located within a region of mouse chromosome 6 that is homologous to a portion of mouse chromosome 7q. The standard product used in this kit is recombinant mouse Leptin. ScienCell's mouse Leptin ELISA Kit is based on standard sandwich enzyme-linked immune-sorbent assay technology. Mouse Leptin-specific monoclonal antibodies are precoated onto 8 x 12 strips. The mouse specific detection monoclonal antibodies are biotinylated. The test samples and biotinylated detection antibodies are subsequently added to the wells and then washed with PBS or TBS buffer. Avidin-Biotin-Peroxidase Complex is added and unbound conjugates are washed away with PBS or TBS buffer. HRP substrate TMB is used to visualize HRP enzymatic reaction. TMB is catalyzed by HRP to produce a blue color product that changes into yellow after adding acidic stop solution. The intensity of yellow is proportional to the amount of mouse Leptin in the sample that is captured in the strips.
