Reagen™chlortetracycline elisa test kit provides a competitive enzyme immunoassay for the quantitative analysis of chlortetracycline in hony, milk, meat and urine. The unique features of the kit are:  rapid , high recovery (80-105%), and cost-effective extraction methods.  high sensitivity (0.05 ng/g or ppb) and low detection limit (2.5ppb for honey sample).  high reproducibility.  a quick elisa assay (less than 2 hours regardless of number of samples). 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 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. kit contents, storage and shelf life reagen™ chlortetracycline 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.

REAGEN™Beta-Lactamase Test Pad Kit is ideal for the routine screening of beta-lactamase in milk. This sensitive kit enables government agencies, food manufacturers and quality assurance organizations to detect beta-lactamase contamination as low as 0.8 UmL.. The unique features of the kit are:  Rapid (less than 40 min)  High sensitivity (0.8 UmL)  High reproducibility Procedure Overview The beta-lactamase test pad provides a qualitative method for detecting beta-lactamase in milk. The nitrocefin is coated on the pad. If there is beta-lactamase in milk, it hydrolyzes the beta-lactam ring of nitrocefin, producing cephalosporanic acid. A distinctive color change is associated with this reaction. The pale yellow nitrocefin turns pink after hydrolysis within the time limits of the test. Kit Contents, Storage and Shelf Life REAGEN™ Beta-Lactamase Test Pad Kit has the capacity for 50 determinations or testing of 48 samples (assuming 2 pads for positive and negative controls). Return any unused Test Pads in Tubes to the foil bag and reseal them with the desiccant provided in the original package. Store the unused Test Pads in Tubes, Negative control and Transfer Pippette at room temperature. Store the Beta-Lactamase Positive Control at -20°C.

Handle with particular care.  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.
