Recombinase Polymerase Amplification-Based Assay to Diagnose Giardia in Stool Samples [PDF]

open access: yesThe American Society of Tropical Medicine and Hygiene, 2015
Giardia duodenalis is one of the most commonly identified parasites in stool samples. Although relatively easy to treat, giardiasis can be difficult to detect as it presents similar to other diarrheal diseases. Here, we present a recombinase polymerase amplification-based Giardia (RPAG) assay to detect the presence of Giardia in stool samples. The RPAG

SDS‐CRISPR for Single‐Nucleotide Variant Detection

open access: yesAdvanced Science, EarlyView.
Structure‐disruption‐sensitive CRISPR (SDS‐CRISPR) converts structural instability into single‐nucleotide precision, thereby overcoming mismatch tolerance in canonical Cas12a and enabling versatile diagnostics across DNA, RNA, and microRNA targets. When applied to rapid IDH1 mutation detection for glioma genotyping and integrated with lateral‐flow ...

Allosteric DNAzyme‐Enabled Sensitive and Multiplex Detection of Biomarkers for Rapid Diagnosis of Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
A catalytic allosteric DNAzyme assay (SMART) is developed by engineering DNAzyme into a unimolecular biosensor, enabling highly sensitive and multiplex detection of small molecules and nucleic acids. SMART enables extraction‐free, one‐pot, one‐step, isothermal, and cost‐effective detection of biological markers, achieving >95% accuracy for rapid ...

Characterization of Sirt2 using conditional RNAi in mice [PDF]

open access: yes, 2011
Within the past eight years, RNA interference (RNAi) has emerged as a powerful experimental tool for gene function analysis in mice. Reversible control of shRNA mediated RNAi has been achieved by using a tetracycline (tet)-inducible promoter.

Transposase‐Assisted Donor Tethering Boosts Large‐Fragment HDR in Plants

open access: yesAdvanced Science, EarlyView.
A transposase‐assisted donor tethering strategy is developed to enhance homology‐directed repair in plants. By recruiting donor DNA to double‐strand breaks and synergizing with repair pathway reprogramming and transcription‐coupled donor design, this system markedly improves large‐fragment targeted insertion efficiency, providing a robust platform for ...

Development of a selection system for the detection of L-ribose isomerase expressing mutants of Escherichia coli [PDF]

open access: yes, 2007
L-Arabinose isomerase (E.C. 5.3.1.14) catalyzes the reversible isomerization between L-arabinose and L-ribulose and is highly selective towards L-arabinose.

Genetic code expansion for chemosensing and chemical actuation of biological functions

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Genetic code expansion (GCE) broadens the chemical repertoire for precise control of protein function in biological systems. This review highlights GCE‐based sensing and actuating systems that operate through selective interactions between noncanonical amino acids and chemical triggers.

Nucleic Acid Amplification using Recombinase Polymerase: Enzymatic Approach

open access: yesJournal of Medical Microbiology & Diagnosis, 2017
Rapid detection of infections is crucial for the prevention of infectious disease outbreaks, development of anti-microbial drugs and biodefense. When considering a diagnostic test the most important considerations are rapidity, ease of use, portability, specificity and sensitivity.
