Furazolidone (AOZ) ELISA Test Kit
Product Description
REAGEN™Furazolidone (AOZ) ELISA Test Kit provides a competitive enzyme mmunoassay for the quantitative analysis of furazolidone in fish, shrimp, meat (chicken, pork and hepar), eggs, honey.
Sensitivity (Detection Limit)
| Sample Type | Detection Limit (ng/g or ppb) |
| Shrimp/Fish/Meat/Hepar | 0.04 |
| Egg/Egg Powder | 0.04 |
| Honey | 0.04 |
Specificity (Cross-Reactivity)
| Analytes | Cross-Reactivity (%) |
| AOZ | 100 |
| AMOZ | <0.02 |
| AHD | < 0.01 |
| SEM | < 0.01 |
1.Rapid (4 hours), high recovery (75 - 105%), and cost-effective extraction methods for various samples.
2.High sensitivity (0.02ng/g or ppb) and low detection limit (0.04 ng/g or ppb) for various samples.
3.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 AOZ antibody are added along with the secondary antibody, tagged with a peroxidase enzyme. If the AOZ residue is present in the sample, it will compete for the AOZ antibody, thereby preventing the antibody from binding to the AOZ-OVA attached to the well. The resulting color intensity, after addition of the HRP substrate (TMB), has an inverse relationship with the AOZ residue concentration in the sample.
Kit Contents, Storage and Shelf Life
REAGEN™ Furazolidone (AOZ) 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.

Do not use the kit past the expiration date.
Do not intermix reagents from different kits or lots except for components with the same part No’s within their expiration dates. ANTIBODIES AND PLATES ARE KIT- AND LOT-SPECIFIC. Make sure that the antibody #2 and diluent are mixed in correct volumes.
Try to maintain a laboratory temperature of 20°–25°C (68°–77°F). Avoid running assays under or near air vents, as this may cause excessive cooling, heating and/or evaporation. Also, do not run assays in direct sunlight, as this may cause excessive heat and evaporation. Cold bench tops should be avoided by placing several layers of paper towel or some other insulation material under the assay plates during incubation.
Make sure you are using only distilled or deionized water since water quality is very important.
When pipetting samples or reagents into an empty microtiter plate, place the pipette tips in the lower corner of the well, making contact with the plastic.
Incubations of assay plates should be timed as precisely as possible. Be consistent when adding standards to the assay plate. Add your standards first and then your samples.
Add standards to plate only in the order from low concentration to high concentration as this will minimize the risk of compromising the standard curve.
Always refrigerate plates in sealed bags with a desiccant to maintain stability. Prevent condensation from forming on plates by allowing them equilibrate to room temperature (20 – 25°C / 68 – 77°F) while in the packaging.
