A Widely Applicable Urea-based Fluorescent/Colorimetric mRNA in situ Hybridization Protocol

open access: yesBio-Protocol, 2019
In situ hybridization methods are routinely employed to detect nucleic acid sequences, allowing to localize gene expression or to study chromosomal organization in their native context. These methods rely on the pairwise binding of a labeled probe to the

Structure, kinetic characterization and subcellular localization of the two ribulose 5-phosphate epimerase isoenzymes from Trypanosoma cruzi [PDF]

open access: yes, 2017
The enzyme of the pentose phosphate pathway (PPP) ribulose-5-phosphate-epimerase (RPE) is encoded by two genes present in the genome of Trypanosoma cruzi CL Brener clone: TcRPE1 and TcRPE2. Despite high sequence similarity at the amino acid residue level,

Effects of Chemical Sterilization and Gamma Irradiation on the Biochemical and Biomechanical Properties of Human Tendon Allografts In Vitro Study

open access: yesOrthopaedic Surgery, 2022
Objective Pre‐implantation sterilization procedures for tendons are important measures to reduce the risk of disease transmission, however these procedures may compromise tendon microarchitecture and biomechanical properties to varying degrees.

Rubredoxin Variant Folds without Iron [PDF]

open access: yes, 1999
Pyroccocus furiosus rubredoxin (PFRD), like most studied hyperthermophilic proteins, does not undergo reversible folding. The irreversibility of folding is thought to involve PFRD’s iron-binding site.

A pipeline for targeted metagenomics of environmental bacteria. [PDF]

open access: yes, 2020
BackgroundMetagenomics and single cell genomics provide a window into the genetic repertoire of yet uncultivated microorganisms, but both methods are usually taxonomically untargeted.

Synthesis and Evaluation of Artificial Nucleic Acid Bearing an Oxanorbornane Scaffold

open access: yesMolecules, 2020
Natural oligonucleotides have many rotatable single bonds, and thus their structures are inherently flexible. Structural flexibility leads to an entropic loss when unwound oligonucleotides form a duplex with single-stranded DNA or RNA.

An improved nucleic acid sequence-based amplification method mediated by T4 gene 32 protein.

open access: yesPLoS ONE, 2022
The uptake of Nucleic Acid Sequence-Based Amplification (NASBA) for point of care testing may be hindered by a complexity in the workflow due the requirement of a thermal denaturation step to initiate the cyclic isothermal amplification before the ...

Measurement of Epstein-Barr virus DNA load using a novel quantification standard containing two EBV DNA targets and SYBR Green I dye [PDF]

open access: yes, 2016
BACKGROUND Reactivation of Epstein-Barr virus (EBV) infection may cause serious, life-threatening complications in immunocompromised individuals. EBV DNA is often detected in EBV-associated disease states, with viral load believed to be a reflection of ...

Microfluidic-Based Amplification-Free Bacterial DNA Detection by Dielectrophoretic Concentration and Fluorescent Resonance Energy Transfer Assisted in Situ Hybridization (FRET-ISH)

open access: yesBiosensors, 2012
Although real-time PCR (RT-PCR) has become a diagnostic standard for rapid identification of bacterial species, typical methods remain time-intensive due to sample preparation and amplification cycle times.

Partial Denaturation of Double-Stranded DNA on Pristine Graphene under Physiological-like Conditions

open access: yesLiquids, 2023
Interactions between DNA and graphene are paramount for a wide range of applications, such as biosensing and nanoelectronics; nonetheless, the molecular details of such interactions remain largely unexplored.
