Single genome sequencing of near full-length HIV-1 RNA using a limiting dilution approach [PDF]

open access: yes, 2019
Sequencing very long stretches of the HIV-1 genome can advance studies on virus evolution and in vivo recombination but remains technically challenging.

Preparation of nuclear matrices from cultured cells: subfractionation of nuclei in situ [PDF]

open access: yes, 1984
Analyses of the different structural systems of the nucleus and the proteins associated with them pose many problems. Because these systems are largely overlapping, in situ localization studies that preserve the in vivo location of proteins and cellular ...

Comparison of Simple RNA Extraction Methods for Molecular Diagnosis of Hepatitis C Virus in Plasma

open access: yesDiagnostics, 2022
Nucleic acid extraction from biological samples is an important step for hepatitis C virus (HCV) diagnosis. However, such extractions are mostly based on silica-based column methodologies, which may limit their application for on-site diagnosis. A simple,

Two-phase wash to solve the ubiquitous contaminant-carryover problem in commercial nucleic-acid extraction kits [PDF]

open access: yes, 2020
The success of fundamental and applied nucleic acid (NA) research depends on NA purity, but obtaining pure NAs from raw, unprocessed samples is challenging.

Detection of MicroRNAs in Dried Serum Blots [PDF]

open access: yes, 2010
MicroRNAs are short RNAs which can be utilized as biomarkers for a variety of conditions. They are detectable in serum, and changes in the levels of circulating microRNAs have been associated with different diseases.

An efficient method for DNA extraction from Cladosporioid fungi [PDF]

open access: yes, 2010
We developed an efficient method for DNA extraction from Cladosporioid fungi, which are important fungal plant pathogens. The cell wall of Cladosporioid fungi is often melanized, which makes it difficult to extract DNA from their cells.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

open access: yesFEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.

A Comprehensive High-Quality DNA and RNA Extraction Protocol for a Range of Cultivars and Tissue Types of the Woody Crop Avocado

open access: yesPlants, 2022
High-quality DNA and RNA forms the basis of genomic and genetic investigations. The extraction of DNA and RNA from woody trees, like avocado (Persea americana Mill.), is challenging due to compounds which interact with nucleic acids and influence ...

Modification of a commercial dna extraction kit to simultaneously recover rna, safely and rapidly, and to assess molecular biomass of the total and the active part of microbial communities, from soils with diverse mineralogy and carbon content : S11.04-P -15 [PDF]

open access: yes, 2012
We have modified a commercial DNA extraction kit for soil to simultaneously co-extract RNA. In this new procedure RNA and DNA are separated by two selective purifications in cascade without the need of DNAase or RNAse digestion.
