False-Positive Clostridium difficile in Negative-Control Reactions Peak and Then Decrease with Repetitive Refrigeration of Immunoassay [PDF]

International Scholarly Research Notices, 2014
Aberrant false-positive reactions in negative-controls during ELISA testing for Clostridium difficile indicated the potential for false-diagnoses. Experiments with 96-well products showed a maximum peak of false-positive immunoassay reactions with the provided negative-control reagents after 5 refrigeration-to-room temperature cycles (P<0.001 ...

Unique circulating miRNAome signatures captured with distinct molecular states in Lynch syndrome and sporadic colorectal cancer

Molecular Oncology, EarlyView.
Circulating microRNA profiles distinguish nonmalignant Lynch syndrome from cancer‐associated Lynch syndrome, sporadic colorectal cancer, and healthy controls. Age‐stratified analysis reveals disease‐specific regulatory states, and a six‐miRNA panel shows concordant separation in an independent colorectal tissue cohort.

PECULIARITIES OF CONTROL OF HUMAN ALBUMIN DRUGS ON THE CONTENT OF BACTERIAL ENDOTOXINS

Разработка и регистрация лекарственных средств, 2019
The problem was considered to determine bacterial endotoxins in human albumin drugs. To improve the safety of medicines the option of dual control was recommended, which includes the rabbit pyrogen test and determining bacterial endotoxins by the LAL ...

Solid phase capture method for the specific amplification of microbial nucleic acids—avoidance of false-positive and false-negative reactions

Molecular and Cellular Probes, 1991
DNA amplification assays such as the polymerase chain reaction are being developed for the amplification of small quantities of microbial nucleic acids. These assays offer the potential for a great deal of sensitivity. However, the high level of sensitivity increases the likelihood of cross-contamination of amplified products and the generation of ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens

FEBS Open Bio, EarlyView.
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Validation of a Commercial Glanders ELISA as an Alternative to the CFT in International Trade of Equidae

Frontiers in Veterinary Science, 2021
Glanders, caused by Burkholderia (B.) mallei is a notifiable zoonotic disease in equidae. For international trade and movement of equids, certificates of negative serological test results for antibodies against B. mallei are required.
