REAGEN™Nitrofurantoin (AHD) ELISA Test Kit provides a competitive enzyme immunoassay for the quantitative analysis of nitrofurantoin in fish, shrimp, meat (chicken, beef, pork, and hepar), eggs, and honey.
Rapid (4 hours), high recovery (80% - 105%), and cost-effective sample extraction methods.
High sensitivity (0.03 ng/g or ppb) and low detection limit (0.06 ng/g or ppb) for various samples.
High reproducibility.
A quick ELISA assay (less than 1 hour regardless of several samples).
The method is based on a competitive colorimetric ELISA assay. The AHD-OVA has been coated in the plate wells. During the analysis, the sample and the AHD antibody are added along with a secondary antibody, tagged with a peroxidase enzyme. If the AHD residue is present in the sample, it will compete for the AHD antibody, thereby preventing it from binding to the AHD-OVA attached to the well. After adding the HRP substrate (TMB), the resulting color intensity has an inverse relationship with the AHD residue concentration in the sample.
REAGEN™Nitrofurantoin (AHD) ELISA Test Kit has the capacity for 96 determinations or testing of 42 samples in duplicate (assuming 12 wells for standards). Return any unused microwells to the foil bag and reseal them with the desiccant provided in the original package. Store the kit at 2-8°C*. The shelf life is 12 months when the kit is properly stored.
