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

    A Novel Affinity Adsorbent For The Capture And Removal Of Endotoxin

    Escherichia coli is a Gram-negative bacteria that is a popular host organism for the expression of recombinant protein bio-therapeutics. Lysis of the outer membrane of Gram-negative bacteria, a requirement to release internalised target biomolecules, also releases substantial quantities of lipopolysaccharides (LPS – also known as endotoxin) into the process solution.

  • Efficient and Cost-Effective Removal Of Residual Endotoxin

    Endotoxin or lipopolysaccharides (LPS) are highly toxic components of the cell wall of Gram-negative bacteria and are often present in significant amounts in bacterial cell culture expression systems such as E. coli.
