Abstract. This year celebrates the 30th anniversary of the licensing of Limulus amebocyte lysate (LAL) by the US Food and Drug Administration (FDA) as a test for the presence of endotoxin in biologicals, pharmaceutical drugs, and medical devices.

LAL is currently recognized by several major pharmacopoeias and is used by: the basis of an assay for endotoxin termed the Limulus amebocyte lysate (LAL) test. InJapanese investigators discovered that endotoxin-activated LAL would also cleave small chromogenic peptides which contained an amino acid cleavage site similar to coagulogen and the chromophore, paranitroanilide (9).File Size: 72KB.
