Here we describe a simple assay for the quantification of the feeding response in hydra induced by the reduced form of glutathione. This assay relies on measuring the distance between the apical end of the tentacle and mouth of hydra.

The ability to successfully make solutions is a basic laboratory skill performed in virtually all biological and chemical experiments. A solution is a homogenous mixture of solute dissolved in bulk liquid known as the solvent. Solutions can be described by their solute concentration, a measure of how much solute is present per unit of solution. In this video, a step-by-step procedure for how to make a water-based, or aqueous, solution for biological applications is presented. The video...

Source: Laboratory of Dr. Michael Evans — Georgia Institute of Technology A solution is a homogeneous mixture containing some components in small amounts, called solutes, and one component in a large amount, called the solvent. Solid-liquid solutions contain one or more solid solutes dissolved in a liquid solvent. Solutions are ubiquitous in chemistry: they are used to store and handle small amounts of material, carry out chemical reactions, and develop materials with controllable properties.

General Properties of Solutions

Many common substances around us exist as a solution, such as ocean water, air, and gasoline. All solutions are mixtures of substances that are composed of varying amounts of two or more types of atoms or molecules. A mixture with a non-uniform composition is a heterogeneous mixture, whereas a mixture with a uniform composition is a homogeneous mixture. The components that make the homogeneous mixture are evenly spread out and thoroughly mixed. A solution is a homogeneous mixture that is...

There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride. This selective solubility...

The sulfhydryl group donates reducing equivalents to reactive oxygen species and oxidized cellular compounds. During this reaction, reduced glutathione, or GSH, becomes glutathione disulfide, or GSSG. This chemical shift allows the solution to participate in controlled oxidation-reduction reactions, making it useful for experiments that examine cellular redox balance and oxidative damage.
The conversion of GSH to GSSG indicates that glutathione has supplied reducing capacity during an oxidation-reduction reaction. Cellular enzymes can regenerate GSH from GSSG, linking glutathione activity to the maintenance of reducing conditions. Measuring or manipulating this relationship can help investigators examine oxidative stress and changes in cellular redox status.
Concentration and pH influence the stability of glutathione solution and can therefore affect experimental results. A selected concentration determines how much reducing reagent is available, while pH contributes to the chemical conditions in which the solution is maintained. Controlling both variables helps make biochemical assays and experimental comparisons more consistent.
Handling conditions should be treated as experimental variables because they can influence solution stability. Researchers need to maintain the intended concentration and pH while preparing and using the solution, particularly when comparing samples or assay results. Consistent handling reduces the likelihood that changes in the preparation, rather than the biological system, account for observed effects.
A biology laboratory may use glutathione solution when an experiment requires a source of reducing capacity. Its applications include biochemical assays and experimental systems focused on oxidative stress, protein thiol status, or detoxification. The selected concentration and pH should match the experimental design because these conditions affect stability and the resulting measurements.
Experiments using glutathione solution can provide information about oxidative stress, protein thiol status, and detoxification-related processes. They may also examine how reducing conditions affect biochemical assay systems. Because glutathione participates in the conversion between GSH and GSSG, the preparation helps researchers investigate changes in redox balance and protection from oxidative damage.
