A Nucleic Acid Test to Diagnose Cryptosporidiosis: Lab Assessment in Animal and Patient Specimens
Author: Crannell ZA, Castellanos-Gonzalez A, Irani A, Rohrman B, White AC, Richards-Kortum R.RPA detection of Cryptosporidium species in DNA extracted from stool samples. TwistAmp nfo based assays were more sensitive than RT-PCR and only needed 30 minutes of amplification time. Using a simple paper and plastic device, lateral flow strips were one […]

Aptamer-based Bio-barcode Assay for Cytochrome-c Detection
Author: Loo JF, Lau PM, Ho HP, Kong SK.Based on a recently reported ultra-sensitive bio-barcode (BBC) assay, we have developed an aptamer-based bio-barcode (ABC) alternative to detect a cell death marker cytochrome-c (Cyto-c) and its subsequent application to screen anti-cancer drugs.

Development of a panel of RPA assays for the detection of biothreat agents
Author: Euler M, Wang Y, Heidenreich D, Patel P, Strohmeier O, Hakenberg S, Niedrig M, Hufert FT, Weidmann M.Syndromic panels for infectious disease have been suggested to be of value in point-of-care diagnostics for developing countries and for biodefense. To test the performance of isothermal recombinase polymerase amplification (RPA) assays, we developed a panel of 10 RPAs for […]

A phaseguided passive batch microfluidic mixing chamber for isothermal amplification
Author: Hakenberg S, Hügle M, Weidmann M, Hufert F, Dame G, Urban GA.With a view to developing a rapid pathogen detection system utilizing isothermal nucleic acid amplification, the necessary micro-mixing step is innovatively implemented on a chip. Passive laminar flow mixing of two 6.5 μl batches differing in viscosity is performed within […]

Optimizing Illumina next-gen sequencing library preparation for at-biased genomes
Author: Oyola SO, Otto TD, Gu Y, Maslen G, Manske M, Campino S, Turner DJ, Macinnis B, Kwiatkowski DP, Swerdlow HP, Quail MA.Oyola et al compared a number of different polymerases and PCR methods with RPA for generating libraries for sequencing AT-rich genomes. The TwistAmp Basic reactions were used without optimisation, simply following the instructions in the Quick Guide.

Recombinase Polymerase amplification assay for rapid detection of Francisella tularensis
Author: Euler M, Wang Y, Otto P, Tomaso H, Escudero R, Anda P, Hufert FT, Weidmann M.We report the development of a novel qualitative real-time isothermal recombinase polymerase amplification (RPA) assay for use on a small ESEQuant Tube Scanner device. The analytical sensitivity and specificity were tested using a plasmid standard and DNA extracts from infected […]

Digital isothermal quantification of nucleic acids via simultaneous chemical initiation of recombinase polymerase amplification reactions on SlipChip.
Author: Shen F1, Davydova EK, Du W, Kreutz JE, Piepenburg O, Ismagilov RFIn this paper, digital quantitative detection of nucleic acids was achieved at the single-molecule level by chemical initiation of over one thousand sequence-specific, nanoliter isothermal amplification reactions in parallel.
