Therapeutic compounds are often first examined in vitro with viability assays. Blind cell counts by a human observer can be highly sensitive to small changes in cell number but do not assess function. Computerized viability assays, as described here, can assess both structure and function in an objective manner.

A technique called Comprehensive Microarray Polymer Profiling (CoMPP) for the characterisation of plant cell wall glycans is described. This method combines the specificity of monoclonal antibodies directed to defined glycan-epitopes with a miniature microarray analytical platform allowing screening of glycan occurrence in a broad range of biological contexts.

Targeted protein degradation represents a major regulatory mechanism for cell function. It occurs via a conserved ubiquitin-proteasome pathway, which attaches polyubiquitin chains to the target protein that then serve as molecular “tags” for the 26S proteasome. Here, we describe a simple and reliable cell-free assay for proteasomal degradation of proteins.

Here we present a fluorophore based imaging technique to detect cell viability on a non-transparent titanium scaffold as well as to detect glimpses of the scaffold impurities. This protocol troubleshoots the drawback of imaging cell-cell or cell-metal interactions on non-transparent scaffolds.
FAQs
Membrane integrity indicates whether the plasma membrane still forms a functional barrier, while metabolic activity shows whether cellular enzymes can carry out indicator reactions. These measurements address related but distinct aspects of cell condition. Using one or both helps researchers distinguish cells with intact boundaries from cells that retain structural features but show reduced biochemical activity after experimental treatment.
Viability stains rely on different cellular responses. Some dyes are excluded when the plasma membrane remains intact, whereas indicator compounds are converted when active enzymes are present. The resulting dye exclusion or chemical conversion provides an observable signal linked to a particular feature of cell health. Selecting between these readouts depends on whether membrane function or metabolic activity is the main question.
Measurements can vary with the history of the cells and the treatment they receive. Isolation, culture, cryopreservation, genetic transformation, and environmental stress can each affect membrane integrity, metabolic activity, or both. Comparing viability across these conditions allows researchers to evaluate how experimental handling influences cell health and to identify conditions associated with better tissue culture or regeneration outcomes.
An assessment begins by choosing a readout based on the biological question, such as membrane integrity or enzyme-dependent activity. Researchers then examine the cells with an appropriate viability stain or indicator response, recording dye exclusion or compound conversion. The result can be compared among treatments, cultures, or stress conditions to evaluate changes in cellular health.
Viability measurements are useful when researchers need to judge the effects of cell isolation, culture conditions, cryopreservation, genetic transformation, or environmental stress. They can reveal whether a treatment preserves living cell function and can help explain differences in growth, regeneration, stress tolerance, or tissue culture efficiency. This makes viability an important outcome for optimizing plant biology experiments.
Viability data can indicate whether cells remain sufficiently healthy after handling or treatment to support later biological outcomes. When paired with observations of growth or regeneration, the measurements help connect cellular condition with tissue culture performance. They also allow researchers to compare experimental conditions and identify approaches that better preserve cell health during plant biotechnology and developmental studies.
