The Limulus amebocyte lysate (LAL) assay was to start with designed within the nineteen sixties and commercialized being a BET inside the U.S. inside the 1970s. The LAL assay is formulated applying specialized blood cells, or amebocytes, attained with the blue blood of Atlantic horseshoe crabs.
Our detailed number of testing alternatives supports your endeavours in pyrogen and endotoxin testing of raw supplies, in-process samples and produced products.
