Flow Cytometric Analysis of Efflux by Dye Accumulation

open access: yesFrontiers in Microbiology, 2019
Gram-negative infections are increasingly difficult to treat because of their impermeable outer membranes (OM) and efflux pumps which maintain a low intracellular accumulation of antibiotics within cells.

G-banding of plant chromosomes [PDF]

open access: yes, 1986
A method for the staining of the chromosomal material of plant cells so as to induce G-Bands, useful in plant genetic studies such as hydridization. G-Banding is induced by contacting living plant cells, such as those of plants of the family Gramineae ...

Single Cell Analysis of Human RAD18-Dependent DNA Post-Replication Repair by Alkaline Bromodeoxyuridine Comet Assay [PDF]

open access: yes, 2013
Damage to DNA can block replication progression resulting in gaps in the newly synthesized DNA. Cells utilize a number of post-replication repair (PRR) mechanisms such as the RAD18 controlled translesion synthesis or template switching to overcome the ...

Caffeine-induced release of small molecules from DNA nanostructures

open access: yesiScience, 2023
Summary: Several planar aromatic molecules are known to intercalate between base pairs of double-stranded DNA. This mode of interaction has been used to stain DNA as well as to load drug molecules onto DNA-based nanostructures.

Ethidium bromide binding to DNA cryogels

open access: yesReactive and Functional Polymers, 2013
Abstract The interaction of the classical intercalator ethidium bromide (EtBr) with the double helical network strands of DNA cryogels was investigated. The cryogels were prepared starting from aqueous solutions of DNA (about 2000 base pairs long) at −18 °C using 1,4-butanediol diglycidyl ether crosslinker under various reaction conditions.
