Modified micromethod of the Limulus amoebocyte lysate assay for endotoxin.
A Limulus amoebocyte lysate microtechnique performed in petrolatum wells on a microscope slide is described. Injection of a dye solution in ethanol directly into the wells leads to an unambiguous interpretation of the results. Twelve samples can be tested on a single slide, and compact storing of the samples is possible.
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...
متن کاملLimulus amoebocyte lysate assay for detection and quantitation of endotoxin in a small-volume parenteral product.
A Limulus amoebocyte lysate gel-clotting method for the determination of endotoxin in a small-volume parenteral product has been described. Sample dilution with 0.1 M potassium phosphate monobasic buffer (pH 8.0) effectively eliminated assay interference, whereas dilution with water did not. The threshold pyrogenic dose for Escherichia coli EC-2 and O127:B8 endotoxins was determined to be 1.0 n...
متن کاملAdaptation of a microdilution procedure to the Limulus lysate assay for endotoxin.
Endpoint determinations of endotoxin by the Limulus amoebocyte lysate assay have been facilitated by use of a microdilution procedure.
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 ...
