背景资料

Vaspin is a newly described adipocytokine expressed predominantly in visceral white adipose tissues. Structure analysis of Vaspin predicts the presence of three β-sheets, nine α-helices, and one central loop, which are distinctive structural features of Serpin family members. The serpins are irreversible ("suicidal”) serine-protease inhibitors, characterized by having more than 30% sequence homology with α1-antitrypsin and a conserved tertiary structure, which contains an exposed reactive center loop that acts as a pseudo-substrate for the target proteinase. Members of this family play an important role in a number of fundamental biological processes including blood coagulation, fibrinolysis, complement activation, angiogenesis, inflammation, and tumor suppression. In human, the serpins represent approximately 2% of total serum proteins, of which 70% is α1- antitrypsin. Vaspin exhibits 40.2% sequence identity with α-1-antitrypsin. Yet, its protease inhibitory activity is still unknown. Vaspin mRNA expression in visceral fat is positively correlated with BMI and percent of body fat. Administration of Vaspin to obese mice improved glucose tolerance and insulin sensitivity, reflected by normalized blood glucose levels. It also led to the reversal of altered expression of diabetes-relevant adipocytokines including leptin, adiponectin, resistin, and TNF-α. These findings suggest a potential clinical use for Vaspin in ameliorating certain aberrations seen in the diabetic/obesity metabolic syndrome. Recombinant human Vaspin is a 45.2 kDa protein containing 395 amino-acid residues.

溶解建议

艾美捷温馨提示:开盖前,请先离心。厂家建议您，按照该货号产品的说明书中要求的方式进行溶解和使用。

保存建议

The lyophilized Vaspin recombinant protein is stable for at least 2 years from date of receipt at -20˚C. Reconstituted Vaspin is stable for at least 3 months when stored in working aliquots with a carrier protein at -20˚C. As with any protein, exposing Vaspin recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
