96 Tests PN: A113248

Components:

45x Ab-conjugated beads (S5P5 - human Adiponectin Ab-bead). PN: A113248A. One vial containing   100 µL of anti-human Adiponectin conjugated to AimPlex Bead S5P5.

25x Biotin-detection Ab (human Adiponectin Biotin-dAb). PN: A113248B. One vial containing   100 µL of biotinylated anti-human Adiponectin.

Lyophilized Standard Mix - Human Adiponectin. PN: A113248S. One vial containing lyophilized Adiponectin.

Application: Optimal antibody pair and antigen standard for assaying human Human Adiponectin. To be used in conjunction with the AimPlex NR Basic Kit (PN: P100001) and a diluent kit. Refer to the AimPlex Multiplex Immunoassay User Manual and kit inserts for the assay procedure.

Note: Some specimens may contain high levels of adiponetin.  For normal serum and plasma samples, pre-diluting samples 500 folds with the Sample Dilution Buffer (PN: P830100) is recommended.  Dilution factors should be optimized according to specific experimental conditions and sample types.

Storage:  2-8 C in the dark.

Important: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

Adiponectin, also known as Acrp30, is a hormone that modulates a number of metabolic processes, including glucose regulation and fatty acid oxidation.  Adiponectin is exclusively secreted from adipose tissue (and also from the placenta in pregnancy) into the bloodstream and is very abundant in plasma relative to many hormones. Levels of the hormone are inversely correlated with body fat percentage in adults; however, a meta analysis was not able to confirm this association in healthy adults. The association in infants and young children is less clear. Similarly, circulating adiponectin concentrations increase during caloric restriction in animals and humans, such as in patients with anorexia nervosa. This observation is surprising, given that adiponectin is produced by adipose tissue; however, a recent study suggests that adipose tissue within bone marrow, which increases during caloric restriction, contributes to elevated circulating adiponectin in this context. Diseases associated with Acrp30 include adiponectin deficiency and chronic pulmonary heart disease.
