The FSTest β-Lactams+Tetracyclines+Streptomycins+CAP+Tylosin Rapid Test Strip works on the immunochromatographic principle. It has a result-reading area with 5 Test (T) lines and 1 Control (C) line—all invisible before testing.

When a sample is applied to the strip's loading side, the liquid flows laterally across the strip’s surface and reacts with pre-coated recombinant antigens. If the sample contains Tylosin (T1), Chloramphenicol (T2), Streptomycins (T3), Tetracyclines (T4), or β-Lactams (T5), the corresponding T line(s) will fade (lighter than the C line). The C line always appears to confirm a valid test. This lets the strip indicate the presence of the above target substances in the sample.

Product Advantages

• 5-in-1 Detection: Covers β-Lactams, Tetracyclines, Streptomycins, Chloramphenicol, Tylosin in raw milk, pasteurized milk, milk powder (20+ substances included).

• High Sensitivity: LODs meet/exceed Chinese standards (e.g., Chloramphenicol: 0.3μg/kg; Streptomycin: 50μg/kg; Tylosin tartrate: 10-20μg/kg).

• Clear Reading: 5 T lines (1 per 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℃ (no freezing).

Preliminary Screening: Qualitative use, ideal for fast preliminary detection.

Kit Composition

Included: 96 test strips, 96 microwells, user manual.Not included: Pipette, microplate, timer, incubator (optional if temp ≥20℃).

Operation Steps

Ø Equilibrate samples/strips to 20-40℃; dissolve milk powder 1:9 with distilled water (use homogeneous samples without clumps, murkiness or odd scents).

Ø Unpack strips/microwells, label, re-cap tube immediately (avoid contamination and moisture).

Ø Add 150μL sample to microwells, mix thoroughly with pipette, incubate 3min (use incubator if room temp<20℃).

Ø Insert strip into microwell, start timing.

Ø Read results within 8min (invalid after 10min).
