  • Abstract
  • Look Inside

The Limulus amebocyte lysate (LAL) test*1 is the most sensitive assay for bacterial endotoxins and it routinely detects picogram amounts in solution. Bacterial endotoxins are lipopolysaccharides associated with the outer membrane of gram-negative bacteria. The endotoxins are also known as pyrogens. Since gram-negative bacteria shed significant amounts of these substances*2 into their environment, a positive Limulus test serves as an index to gram-negative bacterial contamination. Samples not revealing positive bacteriological culture are frequently found to contain endotoxins when assayed with the Limulus test. Therefore, the procedure has been widely used by commercial drug companies for in-line quality control of parenteral materials, as well as for final release of medical devices.*3
