Levonorgestrel ELISA Kit

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

Levonorgestrel is a synthetic progestational hormone with actions similar to those of PROGESTERONE and about twice as potent as its racemic or (+-) -isomer (NORGESTREL) . It is used for contraception, control of menstrual disorders, and treatment of endometriosis.

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to Levonorgestrel (LNG) has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled Levonorgestrel (LNG) and unlabeled Levonorgestrel (LNG) (Standards or samples) with the pre-coated antibody specific to Levonorgestrel (LNG) . 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 Levonorgestrel (LNG) in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of Levonorgestrel (LNG) in the sample.
