Streptomycine (Milk) Test antibiotic residue test kit of milk

Specifications

Streptomycin Rapid Test (Milk)

Cat No.:  W81028-2

1. INTENDED USE
Quicking Streptomycin Rapid Test is a competitive immunoassay for the semi-quantitative detection of the presence of Streptomycin residue in milk.

Cut-off: 150 ppb

Assay Time: 5 – 1 0 min

Sample: milk

2. PRINCIPLE OF THE ASSAY
Quicking Streptomycin Rapid Test is based on competitive lateral flow immunochromatographic assay. The Streptomycin conjugate in the test zone will capture the immuno-gold (colloid gold- Streptomycin antibody conjugate), when there is very little dissociative Streptomycin in the samples. A visible red test band indicates a negative result when the control line (C zone) shows that the card is valid. The test band (T zone) will be not visible if Streptomycin is present in concentration of 1 50 ppb and above which explains a positive result.

2. KIT COMPONENT
- 10× foil pouches each containing a cassette, pipette and desiccant
- 10× centrifugal tubes (1.5 mL)
- Product Manual

3.  TEST PROCEDURE

- Collect 1mL of milk sample and bring it to room temperature (20-30℃).
- Take out the cassette from the foil pouch and place it horizontally.
- Gradually drip 3 drops into the assay sample hole “S”.
- Interpret the result in 5 - 10 min. Result after 10 minutes is only considered as reference.

4. INTERPRETATION OF RESULTS

Positive: Only one clear band in C zone indicates a positive result. Positive shows that the concentration of Streptomycin is at or above 150 ppb in the samples.
Negative: The presence of both clear bands in C zone and T zone.
Invalid: No colored band appears in C zone.

5.  SPECIFICITY
The results are negative when the test card is applied to detect 100 ppm of Chloramphenicol, Macrolides, Neomycin, Gentamicin, Tetracycline and Beta lactam.

6. STORAGE
All materials must be stored at 2 - 8°C. The test kit is stable through the expiration date (18 months) marked on the foil pouch. DO NOT FREEZE.Do not store the test kit in direct sunlight.

7. PRECAUTIONS
- For best results, please strictly adhere to these instructions.
- All reagents must be at room temperature before running the assay.
- Do not remove test cassette from its pouch until immediately before use.
- Do not reuse the test kit.
- Do not use the test beyond its expiration date marked on the foil pouch.
- The components in this kit have been quality control tested as standard batch unit. Do not mix components from different lot
numbers.

8. LIMITATION
Quicking Streptomycin Rapid Test is an useful tool offering a rapid and accurate testing in field screening, exceeding with its convenience. It provides a semi-quantitative method to detect the Streptomycin above 1 50 ppb in milk. If you want a quantitative result, it is suggested to apply other method such as ELISA / HPLC in practice.
