β-Lactams+Tetracyclines+ Sulfonamides+Aflatoxin M1 Rapid Test Strip

Brand: FSTest
CatNO: DP32.4643.5
Specifications: 96 Tests/Kit
Shelf life: 24 months
Application: Intended to test Aflatoxin M1 or/and β-Lactams or/and Tetracyclines or/and Sulfonamides residues in raw milk, pasteurized milk and milk powder samples.Such as goat's milk, camel's milk, and buffalo milk.

The FSTest β-Lactams+Tetracyclines+Sulfonamides+Aflatoxin M1 Rapid Test Strip uses the immunochromatographic principle. It has a result-reading area with 4 Test (T) lines and 1 Control (C) line—all invisible before testing.

When a sample is added to the strip’s loading side, the liquid flows laterally across the strip and reacts with pre-coated recombinant antigens. If the sample contains Aflatoxin M1 (T1), Sulfonamides (T2), Tetracyclines (T3), or β-Lactams (T4), the corresponding T line(s) will fade (lighter than the C line). The C line always appears to confirm a valid test, allowing the strip to indicate the presence of these target substances in the sample.

Product Features
Target Detection:Tests 4 contaminants (Aflatoxin M1, β-Lactams, Tetracyclines, Sulfonamides) in raw milk, pasteurized milk, milk powder (covers over 30 substances).
High Sensitivity: LOD exceeds Chinese standards (e.g., Aflatoxin M1: 0.05μg/kg; Penicillin G: 2-4μg/kg; Tetracycline: 5μg/kg).
Clear Reading: 4 T lines (each for 1 target) + 1 C line (validity check); target presence lightens corresponding T line.
Easy Storage: 30 days stable at room temp; 24 months at 2-8°C (no freezing).
Qualitative Use: For preliminary screening (not precise concentration).
