The method described here allows for the visualization of IL-8 promoter-dependent inflammation activation in the lungs of mice through non-invasive bioluminescence imaging (BLI). The same animal can be subjected to BLI multiple times for up to two months from the time of delivery of the luciferase reporter construct.

External electric field induces a voltage on the membrane of a cell, termed the induced membrane voltage (ΔΦ). By using the potentiometric dye di-8-ANEPPS, it is possible to measure the ΔΦ noninvasively. This video shows the protocol for measuring ΔΦ using di-8-ANEPPS.

This video case report demonstrates the unique management of a duodenal gastrointestinal stromal tumor with a rare, understudied, exon 8 KIT mutation. Neoadjuvant therapy resulted in a 30% reduction in tumor size, making the patient a candidate for a robotic-assisted duodenal sleeve resection instead of the more morbid pancreaticoduodenectomy.

We have recently reported a novel approach for generating fluorogenic DNAzyme probes that can be applied to set up a simple, "mix-and-read" fluorescent assay for bacterial detection. These special DNA probes catalyze the cleavage of a chromophore-modified DNA-RNA chimeric substrate in the presence of crude extracellular mixture (CEM) produced by a specific bacterium, thereby translating bacterial detection into fluorescence signal generation. In this report we will describe key experimental...
FAQs
Antibodies first selectively capture IL-8 from a biological sample. A labeled detection system then generates a measurable signal associated with the captured chemokine. Because the signal is proportional to IL-8 concentration, comparing it with standards converts assay output into a quantitative measurement rather than a simple indication that IL-8 is present.
IL-8, also called CXCL8, functions as a chemokine signal for immune cells, particularly in relation to neutrophil recruitment. Changes in its measured concentration can therefore help characterize inflammatory activity in a biological system. In biology research, this connects assay results to immune signaling and helps investigators examine how inflammation changes across experimental conditions.
Standards provide reference concentrations against which the assay signal can be compared. This calibration establishes the relationship between signal intensity and IL-8 amount, allowing researchers to estimate concentration in an unknown sample. Without that reference, a stronger or weaker signal could indicate a change, but it would not support the same quantitative analysis described for calibrated measurements.
Selective antibody capture helps distinguish IL-8 within a biological sample, focusing the measured signal on the chemokine of interest. This specificity is important when researchers want to relate the assay result to inflammatory activity rather than to the sample’s overall molecular content. It strengthens the biological interpretation of comparisons among samples.
A researcher applies a biological sample to an antibody-based assay, allows IL-8 to be captured, and uses a labeled detection system to generate a signal. The signal is compared with IL-8 standards to estimate concentration. This sequence connects sample handling, selective recognition, signal production, and calibration into one quantitative measurement.
It is useful when investigators need to track changes in inflammatory activity within cell culture experiments or disease models. Measuring IL-8 can help characterize how these systems respond under different experimental conditions or between groups. The resulting data support analysis of immune responses in controlled biological settings.
Measurements can be applied to research on infection, immune regulation, and tissue injury, where inflammatory responses are important experimental outcomes. They can also help assess changes associated with potential anti-inflammatory therapies. By quantifying IL-8, researchers gain a readout for comparing inflammatory activity across models or treatment conditions.
