Carnosine ELISA Kit

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level Carnosine (Car) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level Carnosine (Car) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Carnosine (Car) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Carnosine (Car) and unlabeled Carnosine (Car) (Standards or samples) with the pre-coated antibody specific to Carnosine (Car) . After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of Carnosine (Car) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Carnosine (Car) in the sample.
