0.05ppb Fish Feed Veterinary Drug Residue Test Kit Natamycin ELISA Test Kit

Product Description

         Nitrofurans ELISA Test Kit provides a competitive enzyme mmunoassay for the quantitative analysis of Nitrofurans in fish, shrimp, meat (chicken, pork and hepar), eggs, honey feed.

The unique features of the kit are:

• Rapid (4 hours), high recovery (75 - 105%), and cost-effective extraction methods for various samples.
• Detection limit is 0.05 ng/g.
• A quick ELISA assay (less than 1 hours regardless of number of samples).
• High reproducibility.

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 and the NITROFURANS antibody are added along with the secondary antibody, tagged with a peroxidase enzyme. If the NITROFURANS residue is present in the sample, it will compete for the NITROFURANS antibody, thereby preventing the antibody from binding to the NITROFURANS-OVA attached to the well. The resulting color intensity, after addition of the HRP substrate (TMB), has an inverse relationship with the NITROFURANS residue concentration in the sample.

Kit Contents, Storage and Shelf Life

          Nitrofurans 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.
