New European guidelines for endotoxin testing went into effect on January 1, 2021. These guidelines allow for the use of the synthetic alternative (rFC) in place of the horseshoe crab-derived endotoxin test (LAL) in drug manufacturing. Especially now, when billions of Covid-19 vaccines are in development, it is time to adopt rFC, the more sustainable, more consistent equivalent test.
