• Preparation: Produced from sera of rabbits immunized with highly pure Recombinant Human Vaspin
• Anti-Human Vaspin-specific antibody was purified by affinity chromatography employing an immobilized Human Vaspin matrix Sandwich ELISA: To detect Human Vaspin by sandwich ELISA (using 100 μL/well antibody solution) a concentration of 0.5-2.0 μg/mL of this antibody is required
• This antigen affinity purified antibody, in conjunction with PeproTech Biotinylated Anti-Human Vaspin (500-P256Bt) as a detection antibody, allows the detection of at least 0.2-0.4 ng/well of Recombinant Human Vaspin
• Western Blot: To detect Human Vaspin by Western Blot analysis this antibody can be used at a concentration of 0.1-0.2 μg/mL
• Used in conjunction with compatible secondary reagents the detection limit for Recombinant Human Vaspin is 1.5-3.0 ng/lane, under either reducing or non-reducing conditions
• Vaspin is a newly described adipocytokine expressed predominantly in visceral white adipose tissues
• Structure analysis of vaspin predicts the presence of three beta-sheets, nine alpha-helices, and one central loop, which are distinctive structural features of Serpin family members
• The serpins are irreversible (&quotesuicidal&quote) serine-protease inhibitors, characterized by having more than 30% sequence homology with alpha1-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 humans, the serpins represent approximately 2% of total serum proteins, of which 70% is alpha1-antitrypsin
• Vaspin exhibits 40.2% sequence identity with alpha1-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-alpha
• These findings suggest a potential clinical use for Vaspin in ameliorating certain aberrations seen in the diabetic/obesity metabolic syndrome.
