Gene expression studies can monitor biological processes using a “molecular beacon” (single-stranded DNA, ssDNA), a ...

Microscopic droplets fluoresce bright blue with specks of green. Five droplets in this image (two at the top, two near the center, and one near the bottom) fluoresce blue in varying brightness; each ...

An international collaboration of researchers developed two new complementary approaches for versatile but precise light intensity measurements in fluorescence imaging systems. Accurate measurements ...

It is now possible to obtain three-dimensional, high-resolution images of enzyme activity in tissue samples or whole organs -- thanks to probe molecules that anchor fluorescent dyes within tissue as ...

What is Fluorescence Correlation Spectroscopy (FCS)? Fluorescence correlation spectroscopy (FCS) is a powerful analytical technique that enables the study of dynamic processes and interactions at the ...

"Conventional methods of colorimetry and fluorescence for detecting such enzymes are often restricted by sensitivity or interference from background signals. The ability of rare earth metals to have ...

Traditional analog ELISA readout systems need great volumes, which inevitably dilute reaction products, adding the requirement of millions of enzyme labels to develop signals that can be detected with ...

Traditionally, cytokines have been measured by radioimmunoassays (RIA) and enzyme-linked immunosorbent assays (ELISA). Unfortunately, these techniques are limited by their detection range and an ...
