AccuSift provides high‑performance β‑agonist multi‑residue competitive assay pairings, characterized by exceptional batch‑to‑batch consistency and optimized for IVD kit development (Lateral Flow, Chemiluminescence, ELISA, POCT). These pairings offer high affinity and specificity, facilitating rapid detection."Lean meat powder" is a general term for a class of drugs that inhibit animal fat synthesis and promote lean muscle growth. Substances capable of achieving this effect are mainly β‑agonists (also called β‑adrenergic stimulants). After entering livestock, they alter nutrient metabolism pathways, promote muscle growth—especially skeletal muscle protein synthesis—accelerate fat conversion and breakdown, and increase the lean‑meat ratio.Poisoning incidents due to consumption of "lean meat powder"‑contaminated food have occurred frequently, often with severe consequences, drawing high attention from countries worldwide. To ensure the safety of animal‑derived products and protect human health, many countries have prohibited the use of clenbuterol in food‑producing animals. The U.S. FDA lists clenbuterol residues in meat as a mandatory testing item, and the EU strictly bans the addition of "lean meat powder" drugs in feed. Although China banned the use of "lean meat powder" drugs in 2000, their illegal use in livestock production continues.Performance Specifications
