Modern bioassays tend to fall under three common modalities: colorimetric, luminometric or fluorometric. Colorimetric assays record the amount of light absorbed by a reporter compound. This absorbance ...

Cells In A New Light By combining the sensitivity of fluorescent dyes with optical systems that can detect colorful but low-intensity fluorescent light, researchers in many life sciences are able to ...

Nearly 35 years since Stanford researcher Leonard Herzenberg and colleagues developed the first fluorescence activated cell sorter (FACS), the instrument has become the immunologists' key tool.

Stanford researchers have combined two microscopy techniques to create a one-of-a-kind instrument that can show cell ...

Trypan Blue is widely used in cell culture labs for selectively staining dead cells and tissues. The use of Trypan Blue dye can present challenges for accurately assessing cell counts and viability in ...

Living organisms are made up of hundreds of thousands of cells that cooperate to create the organs and systems that breathe, eat, move, and think. Now, researchers from Japan have developed a new way ...

Biologists are very interested in how proteins, lipids and other compounds are organized and interact in systems. Very few organizational details can be gained by using standard transmission-based ...

Successful cancer surgery depends on a surgeon’s ability to remove tumors, while minimizing harm to healthy tissues. Surgeons currently use glowing dyes which mark cancer cells to help differentiate ...

Cancer is a universal issue which affects many people around the world. Many will turn to surgery in the hope a surgeon will ...
