Bacterial Biosensor Assay for Detecting Bioavailable Mercury Under Anaerobic Conditions04:26

Bacterial Biosensor Assay for Detecting Bioavailable Mercury Under Anaerobic Conditions

211
Source: Stenzler, B. R. et. al., An Anaerobic Biosensor Assay for the Detection of Mercury and Cadmium. J. Vis. Exp. (2018)This video demonstrates the use of genetically engineered bacterial biosensors to accurately measure the bioavailable fraction of mercury ions under anaerobic conditions. By varying the concentration of magnesium sulfate, the assay ensures that the biosensor selectively responds to free mercury ions, as indicated by changes in fluorescence...

Measuring RAN Peptide Toxicity in C. elegans

7.1K
Repeat-associated non-ATG-dependent translational products are emerging pathogenic features of several repeat expansion-based diseases. The goal of the protocol described is to evaluate toxicity caused by these peptides using behavioral and cellular assays in the model system C.

Gap Junctional Intercellular Communication: A Functional Biomarker to Assess Adverse Effects of Toxicants and Toxins, and Health Benefits of Natural Products

15.5K
This protocol describes a scalpel loading-fluorescent dye transfer technique that measures intercellular communication through gap junction channels. Gap junctional intercellular communication is a major cellular process by which tissue homeostasis is maintained and disruption of this cell signaling has adverse health...

Toxic Reactions: Overview01:26

Toxic Reactions: Overview

1.8K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
