Cimaterol ELISA Test Kit
Product Description
REAGEN™Cimaterol ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of cimaterol in feed, meat/tissue, milk and urine. Cimaterol can improve the meat/fat ratio in fattened animals and accelerate livestock growth. They also have a relaxing effect on non-striated musculature and can be used as antiasthmatic and tocolytic agents in human beings. Therefore, excess cimaterol residues in livestock products may lead to health risks for consumers. This has led to a prohibition of cimaterol use in food production. The amount of cimaterol residues can be determined by methods such as HPLC or GC-MS. However, these traditional methods usually require very expensive preparation procedures. Alternatively, enzyme immunoassay (ELISA) can be used as a screening system, which is simple, rapid, sensitive and cost-effective compared with traditional methods.
The unique features of the kit are:
1. Rapid (10 - 30 minutes) extraction method for various samples with high recovery (75 - 95%).
2. High sensitivity (0.25 ng/g or ppb) and low detection limit (0.125 ng/g or ppb for meat/Chicken Liver, 1.25 ng/g or ppb for urine, and 2.5 ng/g or ppb for feed).
3. High reproducibility.
4. A quick ELISA assay (less than 2 hours regardless of number of samples).
Procedure Overview
The method is based on a competitive colorimetric ELISA assay. The drug of interest has been coated in the plate wells. During the analysis, sample is added along with the primary antibody specific for the target drug. If the target is present in the sample, it will compete for the antibody, thereby preventing the antibody from binding to the drug attached to the well. The secondary antibody, tagged with a peroxidase enzyme, targets the primary antibody that is complexed to the drug coated on the plate wells. The resulting color intensity, after addition of substrate, has an inverse relationship with the target concentration in the sample.
