In the dynamic landscape of pharmaceutical manufacturing and quality assurance, the development of testing methodologies remains a cornerstone of ensuring product safety and compliance with regulatory standards. Among these critical testing methods, Bacterial Endotoxin Testing (BET) is a vital quality control measure. Adopting recombinant technologies for BET presents a significant stride toward sustainable and more environmentally friendly testing practices while maintaining the efficiency and reliability of traditional Limulus Amebocyte Lysate (LAL) reagents. This article will overview the developments within recombinant technologies, review peer-reviewed publications on the comparability of PyroSmart NextGen® to LAL reagents, practical implementation of recombinant cascade reagents (rCR) for BET in the laboratory, and navigate the complexities of regulatory implications and industry standards.
