Tetracycline(TET) ELISA Test Kit
Product Description
REAGEN™ Tetracycline (TET) ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Tetracycline in in honey, butter, whey, egg, cheese, milk, meat, meat products such as sausage, fish and shrimp.
The unique features of the kit are:
1. High recovery (75-120%), rapid (less than 30 minutes), and cost-effective extraction methods.
2. High sensitivity (0.05 ng/g or ppb) and low detection limit for samples.
3. High reproducibility.
4. A quick ELISA assay (less than 2 hours regardless of number of samples).
Procedure Overview
REAGEN™ Tetracycline (TET) ELISA Test Kit 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.

Reqired Materials Not Provided With the Kit
1. Microtiter plate reader (450 nm)
2. Vortex mixer, (e.g. Gneie Vortex mixer from VWR)
3. 10, 20, 100 and 1000 mL pipettes
4. Multi-channel pipette: 50-300 mL (Optional)
Warnings and Precautions
1. The standards contain tetracycline. Handle with particular care.
2. Do not use the kit past the expiration date.
3. 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.
4. 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.
5. Make sure you are using only distilled or deionized water since water quality is very important.
6. 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.
7. 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.
8. 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.
9. 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℃ / 68 – 77℉) while in the packaging.
