LAL test and RPT for endotoxin detection of CPT-11/DSPE-mPEG2000 nanoformulation: What if traditional methods are not applicable?

open access: yesAsian Journal of Pharmaceutical Sciences, 2018
Endotoxin detection is an important step in drug characterization. Herein we found that a chemotherapeutic drug nanoformulation composed of irinotecan hydrochloride (CPT-11) and an amphiphilic molecule DSPE-mPEG2000 can interfere with the limulus ...

Determination of endotoxins in sugar with the Limulus test [PDF]

open access: yesApplied and Environmental Microbiology, 1979
The Limulus amebocyte lysate test has been used for determination of pyrogens in sugar of different qualities. All the samples of domestic white sugar and beet raw sugar produced in Sweden during 1976 had a very low content of endotoxins, less than 10 ng/g of sugar. Imported cane raw sugar was, however, highly contaminated.

An in vitro study on factors affecting endotoxin neutralization in human plasma using the Limulus amebocyte lysate test

open access: yesScientific Reports, 2021
Endotoxin neutralization, caused by plasma components, makes it difficult to detect endotoxins in human blood. In this study, we investigated which factors influence the recovery of endotoxins using limulus ameobocyte lysate (LAL)-based assays.

Assessment of Limulus Test for Detecting Endotoxaemia [PDF]

open access: yesBMJ, 1974
The occurrence of endotoxaemia in 46 surgical patients has been investigated using a sensitive preparation of limulus lysate. Altogether 23 patients with local and systemic Gram-negative infections were shown to have endotoxaemia. An overt infection is not a prerequisite for a positive limulus test result, since endotoxin can be absorbed via the ...

The monocyte activation test detects potentiated cytokine release resulting from the synergistic effect of endotoxin and non-endotoxin pyrogens

open access: yesInnate Immunity, 2022
Pyrogens are classified in two groups, endotoxin pyrogens and non-endotoxin pyrogens (NEPs). The presence of either in parenteral pharmaceuticals or medical devices can cause severe harm to subjects, and when occurring in combination, synergistic ...

Avaliação de pirogênios em produtos de uso veterinário pelos testes da hipertermia em coelhos e do lisado de amebócitos do Limulus Pyrogens in veterinary products by the rabbit pyrogen test and the Limulus amoebocyte lysate test

open access: yesCiência Rural, 2007
Realizou-se a avaliação de pirogênios em produtos veterinários de uso parenteral, pelo método da hipertermia em coelhos, calculando-se, para o teste das amostras, doses com concentrações de três a sete vezes superiores à terapêutica.

Elimination of negative feedback in TLR signalling allows rapid and hypersensitive detection of microbial contaminants

open access: yesScientific Reports, 2021
The exquisite specificity of Toll-like receptors (TLRs) to sense microbial molecular signatures is used as a powerful tool to pinpoint microbial contaminants.

Detection of Endotoxin Contamination of Graphene Based Materials Using the TNF-α Expression Test and Guidelines for Endotoxin-Free Graphene Oxide Production. [PDF]

open access: yesPLoS ONE, 2016
Nanomaterials may be contaminated with bacterial endotoxin during production and handling, which may confound toxicological testing of these materials, not least when assessing for immunotoxicity.
