We describe the preparation of ribbons of serial sections and their collection on large transfer support for use as Array Tomography samples, along with automated imaging procedures in a scanning electron microscope. The protocol allows screening, retrieval, and targeted imaging of local, rare events, and the acquisition of large data volumes.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R stands for...

Source: Laboratory of Dr. Andrew J. Steckl — University of Cincinnati A scanning electron microscope, or SEM, is a powerful microscope that uses electrons to form an image. It allows for imaging of conductive samples at magnifications that cannot be achieved using traditional microscopes. Modern light microscopes can achieve a magnification of ~1,000X, while typical SEM can reach magnifications of more than 30,000X. Because the SEM doesn’t use light to create images, the resulting pictures it...

In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the development of increasingly larger leaves and taller plants, to avoid shading by their neighbors, along with the elaboration of root architecture and mechanisms to transport water and...

Source: Danielle N. Beatty and Taylor D. Sparks, Department of Materials Science and Engineering, The University of Utah, Salt Lake City, UT Differential scanning calorimetry (DSC) is an important measurement to characterize thermal properties of materials. DSC is used primarily to calculate the amount of heat stored in a material as it heats up (heat capacity) as well as the heat absorbed or released during chemical reactions or phase changes. However, measurement of this heat can also lead to...

By measuring only one spatial line per acquisition, the system handles fewer data points than a full two-dimensional frame. That reduced measurement burden allows more rapid sequential sampling, which is useful when the specimen changes over time and the experiment prioritizes temporal behavior along a defined path.
A detector or scanning beam samples intensity across the selected line while either the specimen or the imaging system moves. Each line therefore represents a measurement tied to a particular position or moment. Recording these measurements sequentially permits reconstruction of a larger image or creation of a time-resolved signal, depending on the acquisition goal.
The principal difference is the amount of spatial information recorded at one time. A full frame covers a two-dimensional field, whereas line scanning concentrates measurement along one path and obtains additional spatial coverage through sequential acquisition. This tradeoff can streamline workflows and favor rapid analysis of structures or processes extending across that path.
The selected line should correspond to the biological structure or process being examined, because measurements are restricted to that defined path. The relative movement of the specimen and imaging system also matters because it determines how successive line measurements map onto position or time. Matching the line to the experimental question supports meaningful quantitative analysis.
First, select the biological path to be measured and establish the corresponding imaging arrangement. Next, use a detector or scanning beam to record intensity along that line while the specimen or system moves. Finally, organize sequential line measurements into a larger image or time-resolved signal for analysis. This workflow links acquisition directly to the intended biological readout.
The essential elements are a detector or scanning beam, a specimen or imaging system capable of movement, and a defined spatial line for measurement. Their coordinated operation determines how intensity values are collected and ordered. The resulting data can then support image assembly, fluorescence measurement, or quantitative examination of a biological structure.
It suits high-speed microscopy and fluorescence measurements when researchers need efficient sampling rather than a complete two-dimensional field at every instant. It is also valuable for quantitative analysis of structures or processes that extend along a defined path, where sequential line data can reveal spatial or temporal change while keeping the imaging workflow streamlined.
Depending on how the data are organized, the measurements can be assembled into a larger image or interpreted as a time-resolved signal. Intensity values support quantitative analysis, while the reduced data volume can streamline the imaging workflow. These outcomes help connect spatial structure with changing biological behavior along the measured path.
