37. Limulus Amebocyte Lysate Test Using Chromogenic Methods Of Endotoxin Detection

    The bacterial endotoxin detection method using Limulus Amebocyte Lysate (LAL) was developed in the 1960s. Since then, it has served as a highly useful tool in both research and industry. Since the beginning of the century, it was known that the hemolymph of the crab Limulus Polyphemus went through a process of coagulation. By Lisa Komski, M.T., ASCP Senior Manager, Export And LAL; Wako Chemicals USA

38. The Detection Of Endotoxins Via The LAL Test, The Chromogenic Method

    Previous articles in this series covered the gelation and turbidimetric methods used in the Limulus Amebocyte Lysate test for bacterial endotoxins. Here, we focus on the chromogenic method.
