FSTest Salbutamol Rapid Test Kit (10 Tests/Kit)
Product Overview
The FSTest Salbutamol Rapid Test Kit is a high-performance screening solution engineered for the rapid qualitative detection of salbutamol residues in livestock tissues. Salbutamol is a beta-agonist 'lean meat powder' additive that is strictly regulated or prohibited globally due to its potential cardiovascular risks to consumers. This kit delivers reliable, rapid preliminary screening for slaughterhouses, meat processing facilities, food exporters, and regulatory inspectors looking to enforce veterinary drug compliance.
Test Principle
This kit is based on a highly specific lateral flow immunochromatography assay. Once a treated sample is loaded into the sample well, the liquid flows laterally across the test strip via capillary action and reacts with pre-coated recombinant antigens.
Competitive Inhibition Reading: The color intensity of the T (Test) line has an opposite correspondence with the salbutamol concentration. A high level of salbutamol inhibits the line binding.
Result | Visual Line Interpretation | Diagnostic Meaning |
Positive (+) | The T (Test) line appears significantly lighter than the C line or vanishes entirely. | High concentration inhibits the T line; salbutamol residue is present. |
Negative (-) | Both the T line and C line develop a clear, strong red line. | Salbutamol is absent or below the detection threshold limit. |
Invalid | The C (Control) line fails to develop after the liquid is applied. | The test run is invalid. The test must be repeated using a new cassette. |
Target Industries & Applicable Matrices
This screening kit is essential for livestock farm quality assurance, meat processing plants, border customs inspection, and food safety labs. It is strictly optimized for:
· Muscle Tissues: Pork, beef, mutton, and other animal muscle tissues.
⚠️ Critical Sampling Advice: Homogenized tissue samples must consist only of muscle fiber and be completely free of fat to ensure precise, uninterrupted analysis.
Key Advantages & Application Scenarios
· Trace-Level Sensitivity (0.5 μg/kg LOD): Delivers an outstanding Limit of Detection (LOD) of 0.5 μg/kg, ensuring regulatory compliance at international levels.
· Rapid Field Screening: Avoids the immediate delay and high costs associated with heavy laboratory machinery (like LC-MS/MS) during daily arrivals, making it perfect for reception docks or processing floors.
· Chemical Target Accuracy: Programmed to target the specific signature of Salbutamol (CAS No. 18559-94-9, Molecular Weight: 239.31).
· No Cross-Contamination from Common Antibiotics: Tested against high levels (1000 μg/L) of Chloramphenicol with clean, zero-interference negative results. (Note: Due to structural family similarities, clenbuterol hydrochloride may cause cross-reactions).
Simple Step-by-Step Assay Procedure
Achieve reliable visual confirmation in less than 30 minutes with these simple steps:
1. Extraction: Weigh 4g of homogenized muscle tissue into a 15mL centrifuge tube, add 0.5mL of extracting solution, and vortex or shake for 1 minute.
2. Heat & Centrifuge: Place the tube upright in an 80°C water bath for 10 minutes (ensure the outer water level is higher than the internal sample). Centrifuge at 4000 rpm for 3 minutes, then cool the supernatant back down to room temperature.
3. Microwell Reaction: Bring the cassette to a 20–40°C environment. Pipette 100µL of the cooled supernatant into a microwell, mix 3–5 times, and let it stand for 3 minutes.
4. Load & Read: Transfer the entire mixed volume into the sample well of the cassette. Interpret the visual lines between 8–10 minutes.
⚠️ Critical Warning: Results become entirely invalid after 10 minutes.
