Reagentless Real‐Time ATP Monitoring with New DNA Aptamers

Small, EarlyView.
A new aptamer is discovered via in vitro selection that binds to adenosine triphosphate (ATP) with high affinity (KD = 0.7 µm) and rejects closely related analogs including adenosine diphosphate (ADP), adenosine monophosphate (AMP), and adenosine. A fluorescent molecular beacon based on the aptamer enables continuous analyte monitoring in cell culture ...

Toxicity of Commonly Used Plasticizers to the Freshwater Organisms Tilapia sparrmanii (Fish) and Caridina nilotica (Shrimp): Lethal and Sublethal Effects

Environmental Toxicology, EarlyView.
ABSTRACT The toxicity of microplastics in aquatic environments is usually due to plasticizers, the chemical additives that keep the plastic polymers together. Thus, the current study reports on the toxicity of three common plasticizers found in freshwater ecosystems and their impacts on two South African freshwater organisms at the organismal and ...
