AccuSift provides high-performance β-lactam receptor 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.

The β-lactam receptor (β-lactams receptor) is a class of specialized proteins on the bacterial cell membrane, belonging to the Penicillin-Binding Proteins (PBPs) family. It serves as the target for β-lactam antibiotics. Its core function is to recognize and bind β-lactam antibiotics (e.g., penicillins, cephalosporins), disrupting the synthesis of bacterial cell wall peptidoglycan, ultimately leading to bacterial lysis and death.
