Protocol for high-sensitivity/long linear-range spectrofluorimetric DNA quantification using ethidium bromide

BioTechniques, 2007
Ethidium bromide (EtBr) is the most widely used fluorescent dye in nucleic acid gel electrophoresis since decades. However, it has been essentially forgotten in DNA quantification by spectrofluorimetry.

Prevalence and Genomic Characterization of mcr‐Positive Enterobacteriaceae in Retail Meat in Thailand Following the Colistin Ban

Microbiology and Immunology, EarlyView.
ABSTRACT This study aimed to investigate the prevalence and characteristics of mcr‐positive Enterobacteriaceae in retail meat in Thailand following the national ban on prophylactic colistin use in food producing animals. A total of 152 meat samples (103 chicken and 49 pork) were collected from supermarkets and open markets between July and September ...

A Novel Antioxidant Peptide Cath‐Np Derived from Nanorana parkeri Attenuates UVB‐Induced Skin Photodamage in Mice

Integrative Zoology, EarlyView.
Schematic representation of Cath‐Np as an antioxidant suppressing acute skin damage caused by ultraviolet B (UVB) radiation in mice. Cath‐Np inhibits the activation of p53 and mitogen‐activated protein kinase pathways while it activates the Nrf2 pathway by its strong antioxidant effects, and accordingly suppresses the expression of inflammatory factors

Application of the comet assay in erythrocytes of Oreochromis niloticus (Pisces): a methodological comparison

Genetics and Molecular Biology, 2009
The present study applied the comet assay to erythrocytes of Oreochromis niloticus with the aim of improving protocols to detect DNA damage in these cells, by using two distinct pHs (pH = 12.1 and pH > 13) and evaluating whether there is a correspondence

Quantification of DNA samples by Ethidium Bromide Spot Technique

, 2018
Accurate and quick determination of DNA concentration is critical for the assembly of synthetic constructs, as well as a multitude of other experiments. We sought to optimize an under-utilized and inexpensive approach for determining DNA concentration: a

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

Conservation Biology, EarlyView.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.

Uroporphyria development in cultured chick embryo fibroblasts long-term treated with chloramphenicol and ethidium bromide

, 1984
Long-term chloramphenicol- and ethidium bromide-treated chick embryo fibroblasts synthesize large amounts of porphyrins from exogenously added σ-aminolevulinic acid. The porphyrins consist mainly of uro- and heptacarboxyporphyrins and are retained within
