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 کاملStatistical determination of endotoxin content in influenza virus vaccine by the limulus amoebocyte lysate test.
To determine laboratory-to-laboratory variability of the limulus amoebocyte lysate (LAL) test for evaluating endotoxin content in influenza virus vaccine, a collaborative study was designed. Participants were six influenza virus vaccine manufacturers and the Bureau of Biologics (BoB). Lysate lot 116, Reference Influenza Virus Vaccine for Endotoxin Assay E-1, and four test vaccines having differ...
متن کاملDetection of endotoxin in antibiotic solutions with Limulus amoebocyte lysate.
Twenty-eight antibiotics were tested with the Limulus amoebocyte lysate assay to determine their non-inhibitory concentrations (NICs). The Limulus amoebocyte lysate assay was found to be a valid test for most of the antibiotics tested; the NICs were found to be greater than the minimum valid test concentrations. Borderline results were obtained with cefamandole nafate and neomycin sulfate. Poly...
متن کاملStudies on Limzdus Amoebocyte Lysate
A pro-clotting enzyme capable of causing the gelation of clottable proteins in Limulw polgphemus (horseshoe crab) has been purified to apparent homogeneity as judged by sodium dodecyl sulfate-gel electrophoresis. The activation of the pro-clotting enzyme depended on the presence of both Ca’+ and endotoxin. It contained y-carboxyglutamic acids and gave a single NlI,-terminal lysine. The enzyme w...
متن کاملRapid detection of gram-negative bacterial peritonitis by the Limulus amoebocyte lysate assay.
The chromogenic Limulus amoebocyte lysate test effectively detected 66 (100%) culture-proven gram-negative peritonitis cases among 185 continuous ambulatory peritoneal dialysis patients with clinical evidence of infectious peritonitis.
