The PCR test requires a skilled laboratory technician, special equipment and up to an hour or more to process. Often, results are not available until one or two days after the test. Additionally, testing on a massive scale can only be conducted at a large, centralized facility, such as a ...
Library preparation of WGA samples was completed using the Rapid PCR barcoding Kit SQK-RPB004 (Oxford Nanopore Technologies) for‘1mL standard protocol’samples due to typically low DNA yields following host depletion, and for samples processed through the5mL quick-enrichment’protocol, the Rapid Barc...
Staphylococcus aureus(S. aureus) andEscherichia coli(E. coli) were chosen as the test targets of Gram-positive bacteria and Gram-negative bacteria, respectively, in this study to demonstrate the performance of the SERS-AST method on clinical positive blood-culture samples acquired from patients with...
The external comparison confirmed high agreement of both the Elecsys assay and the Anti-SARS-CoV-2 Rapid Antibody Test, also with no confirmed PCR result and time of sampling from symptom onset unknown. For both the internal and external evaluation, samples could be mixed with some collected ...

Containment measures including on-site and sensitive detection of COVID-19 are an urgent key to protecting health and preventing the spread of the pandemic. The official and gold standard for detecting SARS-CoV-2 approach is reverse transcription-polymerase chain reaction (RT-PCR) [3]. However,...
PCR to generate linear expression templates (LETs) for CFPS. Linear expression templates were amplified via PCR using the pJL1_LET_F (ctgagatacctacagcgtgagc) and pJL1_LET_R (cgtcactcatggtgatttctcacttg) primers in a 50 μL PCR reaction using the Q5 Hot Start DNA polymerase (NEB, M...
As an alternative, there are different molecular methods that entail near-time or real-time pathogen detection, among them immunoassays and tests for nucleic acids specific of the pathogen. The advent of polymerase chain reaction (PCR) as a tool for in vitro nucleic acid amplification has led ...
The validation process involved analyzing 65 clinical samples, of which, 39 were positive and 26 were negative, and they had already undergone PCR testing. The researchers also assessed the performance of the test kits when detecting IgG or IgM antibodies. The EUROIMMUN Anti-SARS-CoV-2 ELISA ...
the sensitivity of the RPA-LFA assay for the detection ofE. faecalisin tap water, saline water and in wastewater was 10–1000 times lower than that of the Enterolert-E test, depending on the water quality. Nevertheless, with further improvements, this low-cost RPA-LFA may be suitable to...
