Product Description

 

Rapid Test Kit for Ractopamine
1. Principle
This kit is based on competitive indirect immunochromatography technology, in which ractopamine in sample competes for the colloid gold labeled antibody with ractopamine coupling antigen captured on test line. The test result can be watched by naked eye.
2. Application
This kit is intended for rapid test of ractopamine residue in porcine urine.
3. Detection limit
Detection limit for urine sample: 3 ng/g(ppb)
4. Kit components

Ractopamine cassette ---- 50 pcs

Pipette ---- 50 pcs

Kit Insert ---- 1pcs

5. Sample preparation
Collect urine samples in clean, dry, antiseptic-free plastic cup or glass. The collected sample can be stored at 2-8ºC for 24 hours, or stored at -20ºC for long period. Avoid repeated freeze and thaw.  
6. Assay procedure

1. Bring all the test samples to room temperature before experiment. Please centrifuge for 5min at 3000rpm if the sample is muddy.
2. Take the test strip from the package, and use for assay within 1 hour.
3. Place the test strip at a flat level, pipette the prepared sample solution and add 2-3 drops into the sample region.
4. Start the timer as the added solution flows, observe the result within 10min, determine the result according to part 7.

7. Result interpretation
Negative (-): Test Line(Line T) and Control Line(Line C) are both red, indicating that the ractopamine in sample is lower than the LOD of the kit.
Positive (+): No color shows in Test line(Line T), indicating that the ractopamine in sample is higher than the LOD of the kit.
Invalid: No color shows in Control Line(Line C), indicating the operation is incorrect or the test kit is out of date. In this case, please read the instruction again carefully, and do the assay again with new strips.
               
8. Notice
