Import Beta-Lactams & Tetracyclines Combo Test Kit — Buy in wholesale FOB from Supplier in China

This Beta-lactams & Tetracyclines Combo Test Kit is a lateral-flow immunochromatographic assay manufactured by Huaan Magnech Bio-tech Co., Ltd. in Beijing, China, for the simultaneous detection of beta-lactam and tetracycline antibiotic residues in raw and pasteurised milk. The kit targets Penicillin G at 2-4 ug/kg, Amoxicillin at 4-5 ug/kg, Ampicillin at 3-4 ug/kg, Cefquinome at 10-15 ug/kg, Cloxacillin at 2-5 ug/kg, Cefalonium at 4-8 ug/kg, Ceftiofur at 70-90 ug/kg, Oxacillin at 3-6 ug/kg, Cephapirin at 4-8 ug/kg, Nafcillin at 8-12 ug/kg, Cefoperazone at 3-6 ug/kg, Cefacetrile at 20-30 ug/kg, Dicloxacillin at 2-5 ug/kg, Cefazolin at 40-50 ug/kg, and Benzathine at 2-4 ug/kg within the beta-lactam group, plus Tetracycline at 20-35 ug/kg, Doxycycline at 10-18 ug/kg, Chlortetracycline at 15-25 ug/kg, and Oxytetracycline at 15-25 ug/kg within the tetracycline group.

The assay format uses antibody-coated colloidal gold particles or nanoparticles that migrate along a nitrocellulose membrane, binding to immobilised drug-protein conjugates at the test line in the absence of target residues. A control line validates assay integrity. The test strip components include a sample pad, conjugate pad containing enzyme or gold-labelled antibodies, nitrocellulose membrane with pre-printed test and control zones, and an absorbent pad. Reaction buffers and standards for calibration are supplied in lyophilised or liquid form. The typical detection format is qualitative or semi-quantitative, with visual interpretation or optional reader-based quantification. Cross-reactivity profiles vary by antibody clone; the stated limits represent conservative thresholds for screening compliance with Codex Alimentarius and EU MRL regulations for milk.

Dairy processors, milk collection centres, and third-party testing laboratories use this kit for incoming tanker screening, bulk-tank monitoring, and export certification. The rapid format suits high-throughput environments where batch release decisions require results within minutes rather than hours. Importers should verify that the antibody lot has been validated against their target matrix (cow, goat, or sheep milk) and that cross-reactivity data covers regional veterinary drug usage patterns. Storage at 2-8 degrees Celsius preserves reagent stability; room-temperature shipping stability and shelf-life documentation should be requested from the supplier before ordering.

Huaan Magnech Bio-tech Co., Ltd. is located at No. 6 Chaoqian Road, Changping District, Beijing 102200, China. The supplier holds a harbor trust tier on the platform, with a recorded response rate of 0.00 percent and an average response time of zero hours, which indicates that direct communication metrics are not available or not yet established through the platform interface. Buyers should treat this as a signal to initiate contact early and confirm responsiveness through direct channels before relying on time-sensitive procurement schedules.

The supplier's profile does not state manufacturing certifications (ISO 13485, GMP, or CE-IVD), production capacity, number of employees, annual revenue, or specific client references. The listing concentrates on limit-of-detection data for sixteen individual analytes rather than operational or corporate history. Importers are advised to request a copy of the quality management system certificate, batch-to-batch consistency data, and stability validation studies directly from Huaan Magnech Bio-tech to support their supplier qualification process.
