REAGEN™ofloxacin ELISA Test Kit enables government agencies, food manufacturers and quality assurance organizations to detect ofloxacin to as low as 0.1 ppb level in various sample types and to satisfy customer concerns about food safety. The features of the kit are:
The extraction of ofloxacin from meat/tissue with a high recovery rate.
A quick ELISA assay (less than 1.5 hours regardless of number of samples).
High reproducibility.Procedure Overview
Procedure Overview
The method is based on a competitive colorimetric ELISA assay. The ofloxacin antibody has been coated in the plate wells. During the analysis, sample is added along with the ofloxacin-horseradish peroxidase (Ofloxacin-HRP) conjugate. If the ofloxacin residue is present in the sample, it will compete for the ofloxacin antibody, thereby preventing the Ofloxacin-HRP from binding to the antibody attached to the well. The resulting color intensity, after addition of the HRP substrate (TMB), has an inverse relationship with the ofloxacin residue concentration in the sample.
Kit Contents, Storage and Shelf Life
REAGEN™ ofloxacin 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.
