Endotoxins and Their Detection with the Limulus Amebocyte Lysate Test
In contrast to the detailed descriptions of techniques provided by Larsson, a chapter on the measurement and analysis of acetylcholine written by Israel Hanin takes the form of a brief but comprehensive survey of all of the methods for the quantitation of acetylcholine introduced between 1933 and 1981. Each method presented is referenced and briefly critiqued. This is followed by an article by ...
متن کاملActivation and inhibition of Limulus amebocyte lysate coagulation by chemically defined substructures of lipid A.
Recent work with lipid mutants of Escherichia coli and Salmonella typhimurium has helped to elucidate the correct structure of lipid A and has suggested a biosynthetic pathway. Precursor molecules include diacylglucosamine 1-phosphates and tetraacyl disaccharide bis-phosphates. The activities of several of these compounds and of their derivatives were measured by Limulus amebocyte lysate (LAL) ...
متن کاملBiomedical Applications of Limulus Amebocyte Lysate
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 worldwide. That a suitable alternative for the detection of endotoxin has not supplanted...
متن کاملMeasuring of free endotoxin in alum-precipitated vaccine of haemorrhagic septicaemia by limulus amebocyte lysate test
Haemorrhagic septicaemia (HS) vaccine which is prepared in Razi Institute is used in endemic areas ofIran. Aluminum-hydroxide gel was used as adjuvant for preparing this vaccine. Post-vaccinal shock reactionswere the main complaint after use of this vaccine. In a previous study, we could improve the vaccine byalum-precipitation Pasteurella multocida cells and removing the liquid phase. In this ...
متن کاملSingle-step, chromogenic Limulus amebocyte lysate assay for endotoxin.
A new reagent for the chromogenic Limulus amebocyte lysate (LAL) assay is described. LAL was formulated for optimal performance in either an endpoint procedure or a kinetic procedure with the chromogenic substrate, buffer, and LAL components colyophilized as a single reagent. The kinetic chromogenic method required an incubating microplate reader coupled to a computer for collection and analysi...
