Methods

This is a close-up shot of a scientist or lab technician at work. The person, wearing a white lab coat and blue disposable gloves, is holding a 96-well microplate containing a blue liquid. With their other hand, they are using a micropipette to carefully dispense a sample into one of the wells, suggesting a scientific experiment or analysis is in progress.
ELISA
The image shows numerous cells with their nuclei stained in a bright blue color and other parts of the cells, likely specific proteins or structures, stained in a vibrant green fluorescence against a dark, black background. The cells have a speckled or granular appearance within their nuclei. The image is a typical representation of immunofluorescence microscopy.
IFA
The image shows a laboratory environment. You can see a test tube rack with several test tubes filled with a red liquid. A pipette is being used to add another sample to one of the test tubes.
RIA
The image is a graphic representation of a test strip, for a LINE assay. The strip is shown at an angle, with several different colored or shaded segments on it, and the code "V8978.1.1" is visible on the top right segment. The strip is overlaid on a blurred background of a modern-looking laboratory with various pieces of equipment.
LINE & Dot
This image shows a close-up of a laboratory scene where a person wearing blue gloves is using a pipette to transfer a liquid sample into a well plate. On the table, there are additional laboratory supplies, including a small bottle with a white cap and a white container with a label.
Rapid tests
This image depicts a modern, well-equipped laboratory. The workspace is filled with various scientific instruments, glassware, and computers. On the left side, there are bottles, test tubes, and other lab materials neatly arranged on the counter. In the center, there are additional laboratory tools, including a notebook and pipettes. The background features advanced equipment, such as microscopes and incubators, with a clean and organized appearance. The overall atmosphere suggests a high-tech research environment focused on scientific experiments and analysis.
