Solutions are utilized to some degree in almost all biological research applications. Therefore understanding how to measure and manipulate them is imperative to any experiment. In this video, concepts in preparing solutions are introduced. Solutions consist of a solute dissolved in solvent to yield a homogeneous mixture of molecular substances. Solutions are generally identified by their components and corresponding concentrations. Concentrated solutions are diluted through various...

In this video, we demonstrate an EGFP-based immunofluorescence assay to identify the efficacy of target proteins on the neurite outgrowth of primary cortical neurons. The primary neurons are transfected with a fluorescent protein, EGFP, and a target protein, and then an immunoassay is performed to investigate the effect of the target protein on neurite outgrowth.

Here we present a protocol to simply and reliably measure the lung pressure-volume curve in mice, showing that it is sufficiently sensitive to detect phenotypic parenchymal changes in two common lung pathologies, pulmonary fibrosis and emphysema. This metric provides a means to quantify the lung’s structural changes with developing pathology.

Neurite outgrowth assays provide a quantitative value about regenerative neuronal processes. The advantage of this semi-automatic software is that it segments cell bodies and neurites separately by creating a mask and measures various parameters such as neurite length, number of branch points, cell-body cluster area, and number of cell clusters.
FAQs
The analysis first separates labeled neuronal processes from surrounding background, then converts the segmented signal into spatial data for volume calculation. This distinction matters because inaccurate inclusion of background or exclusion of neurite signal can change the resulting structural measurement. It therefore provides a basis for comparing neuronal conditions, treatments, or stages of structural change.
Three-dimensional analysis allows the measurement to represent the amount of neuronal process structure across spatial data rather than relying only on a planar image. This is relevant when neuronal processes change in extent, branching, or degeneration, because the calculated value can serve as a quantitative structural readout. The approach connects imaging data with changes in neural structure.
A measured increase or decrease in neurite volume can indicate changes in neuronal structure associated with growth, branching, or degeneration. Comparing values across experimental conditions may show whether a treatment or other intervention alters these processes. The measurement therefore translates visible changes in neuronal morphology into quantitative data that can support interpretation of neural responses.
Surrounding background must be distinguished from labeled neurites before spatial volume is calculated. If background signal is included, the estimated volume may be artificially increased; if neurite signal is missed, the value may be reduced. Careful separation is therefore central to obtaining a structural measurement that meaningfully reflects the neuronal processes present in the microscopy images.
A typical workflow begins with microscopy images containing labeled neuronal processes. The analysis distinguishes neurites from the surrounding background, segments the relevant structures, and uses the resulting spatial data to calculate their three-dimensional volume. Researchers can then compare the measurements across experimental conditions to assess structural changes such as growth, branching, degeneration, or treatment responses.
Researchers may use this approach when an experiment asks whether neuronal structure changes during development, degeneration, disease-related processes, or exposure to a compound. It is especially useful when visual inspection alone does not provide a sufficiently quantitative comparison. The resulting volume measurement offers a structural outcome for evaluating differences among experimental conditions or treatments.
Neurite volume measurement provides a quantitative way to examine structural effects associated with neurotoxicity or disease mechanisms. A change in measured volume can be evaluated alongside the experimental condition to determine whether neuronal processes are altered. The same readout can also help assess compounds that modify neuronal morphology, supporting comparisons of their effects on neural structure.
