Zilpaterol ELISA Test Kit
Product Description
REAGEN™ Zilpaterol ELISA Test Kit is a competitive enzyme immunoassay for the quantitative analysis of Zilpaterol in feed, tissue (muscle, liver), serum and urine.
The unique features of the kit are:
1.Rapid (10 - 30 minutes), and organic reagent-free extraction method for various samples with high recovery (80 - 95%).
2.High sensitivity (0.15 ng/g or ppb).
3.A quick ELISA assay (less than 2 hours regardless of number of samples).
4.High reproducibility.
Procedure Overview
The method is based on a competitive colorimetric ELISA assay. The zilpaterol Antibody has been coated in the plate wells. During the analysis, sample and HRP-Conjugated are added to the wells. If the target is present in the sample, it will compete for the antibody, there by preventing the HRP-Conjugated from binding to the zilpaterol antibody attached to the well.The resulting color intensity, after addition of substrate, has an inverse relationship with the target concentration in the sample

Warnings and Precautions
1．The standards contain Zilpaterol. 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. Make sure that the HRP Conjugate and Diluent are mixed in correct volumes.
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 insulate 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°C /68 – 77°F) while in the packaging.
