How to Process Sputum Samples and Extract Bacterial DNA for Microbiota Analysis [PDF]

open access: yes, 2018
Different steps and conditions for DNA extraction for microbiota analysis in sputum have been reported in the literature. We aimed at testing both dithiothreitol (DTT) and enzymatic treatments of sputum samples and identifying the most suitable DNA ...

Evaluation of two DNA extraction methods for the PCR-based detection of eukaryotic enteric pathogens in fecal samples

open access: yesBMC Research Notes, 2018
Efficient and easy-to-use DNA extraction and purification methods are critical in implementing PCR-based diagnosis of pathogens. In order to optimize the routine clinical laboratory diagnosis of eukaryotic enteric pathogens, we compare, via quantitative ...

Cellular liquid biopsy provides unique chances for disease monitoring, preclinical model generation and therapy adjustment in rare salivary gland cancer patients

open access: yesMolecular Oncology, EarlyView.
We quantified and cultured circulating tumor cells (CTCs) of 62 patients with various cancer types and generated CTC‐derived tumoroid models from two salivary gland cancer patients. Cellular liquid biopsy‐derived information enabled molecular genetic assessment of systemic disease heterogeneity and functional testing for therapy selection in both ...

Lipopolysaccharide is a frequent contaminant of plasmid DNA preparations and can be toxic to primary cells in the presence of adenovirus [PDF]

open access: yes, 1994
Endotoxin (lipopolysaccharide, LPS) is commonly found as a contaminant in plasmid DNA preparations. We demonstrate here that the quantities of LPS typically contaminating DNA preparations can generate a toxicity to primary cells (primary human skin ...

Automatic detection of spermatozoa for laser capture microdissection [PDF]

open access: yes, 2008
In sexual assault crimes, differential extraction of spermatozoa from vaginal swab smears is often ineffective, especially when only a few spermatozoa are present in an overwhelming amount of epithelial cells.

Frugal method for extracting DNA from saliva suitable for low-budget labs and usable in PCR assays

open access: yesJournal of BioScience and Biotechnology
Blood is the preferred source of DNA as it yields large quantities of high-quality DNA. However, there are challenges associated with this process, including difficulty in finding small and thin veins, rigid veins due to aging, and individuals with ...

Robust CTAB-activated charcoal protocol for plant DNA extraction

open access: yesActa Agriculturae Slovenica, 2006
DNA extracted from plants rich in polyphenols and/or polysaccharides is often problematic when subjected to polymerase chain reaction, especially when mature tissues are used for DNA extraction.

Combined spatially resolved metabolomics and spatial transcriptomics reveal the mechanism of RACK1‐mediated fatty acid synthesis

open access: yesMolecular Oncology, EarlyView.
The authors analyzed the spatial distributions of gene and metabolite profiles in cervical cancer through spatial transcriptomic and spatially resolved metabolomic techniques. Pivotal genes and metabolites within these cases were then identified and validated.
