QuicKey Pro Human ADP/Acrp30 (Adiponectin) ELISA Kit (E-OSEL-H0024)

This ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Human ADP/Acrp30. Samples (or Standards) and Horseradish Peroxidase (HRP) linked antibody specific for Human ADP/Acrp30 are added to the micro ELISA plate wells. Human ADP/Acrp30 in samples (or standards) combines with the coated antibody and HRP linked detection antibody special to Human ADP/Acrp30.Excess conjugate and unbound sample or standard are washed from the plate. The substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Human ADP/Acrp30. The concentration of Human ADP/Acrp30 in the samples is then determined by comparing the OD of the samples to the standard curve.

Adiponectin contains 244 amino acids with a collagen-like domain at the N-terminal and a globular domain at the C-terminal. The globular domain can be proteolytically truncated forming the globular adiponectin (gAdiponectin). This globular domain resembles the structure of the complement C1q and the TNF-α superfamily. Adiponectin exists in a wide range of homo-oligomers: a low-molecular weight (LMW) trimer, a medium molecular weight (MMW) hexamer, and a high molecular weight (HMW) multimer with little or no interconversion between the forms. Females generally have higher HMW than males in proportion and absolute amounts. Adiponectin has two receptors (adipoRs)-1 and -2. AdipoR1 mRNA is detectable in skeletal muscle, spleen, lung, heart, kidney, and liver. AdipoR2 is expressed in liver, but is also detectable in heart, lung, skeletal muscle, and kidney.Adiponectin plays an important role in carbohydrate and lipid metabolism. It promotes insulin-sensitivity and protects cells from inflammation and apoptosis. It is also hypothesized to have anti-atherogenic activity. Normal circulating adiponectin level ranges from 4-30 µg/mL. Adiponectin levels are inversely correlated with body mass index (BMI). Low serum level of adiponectin is found in obesity, type 2 diabetes and those with coronary artery disease. Therefore, adiponectin serves as an important clinical biomarker for metabolic syndromes
