Fluorescence Microscopy News and Research

RSS

Fluorescence microscopy is an imaging technique used to examine cells and their internal components. Specific cellular components can be labeled with fluorophores.

Scientists discover the central role of LRRC8A gene in cellular ability to survive osmotic shock

Cells have to constantly adapt to their surroundings in order to survive. A sudden increase in the environmental levels of an osmolyte, such as salt, causes cells to lose water and shrink. In a matter of seconds, they activate a mechanism that allows them to recover their initial water volume and avoid dying.

Study could help develop peptide siRNA carrier for human oral cancer

MUSC Hollings Cancer Center researchers are exploring the use of peptide carriers for the delivery of small RNA drugs as a novel treatment for cancer. The team's recent work, published online March 19 in the Molecular Therapy - Nucleic Acids journal, lays the foundation for developing a clinically relevant peptide carrier RNAi-based drug treatment strategy for human oral cancer.

New approach to biomaterial production may ease environmental burden of forestry, agriculture

It takes a lot to make a wooden table. Grow a tree, cut it down, transport it, mill it ... you get the point. It's a decades-long process. Luis Fernando Velásquez-García suggests a simpler solution: "If you want a table, then you should just grow a table."

Altered sugar composition impacts cell-to-surface adhesion

Biotechnologists measure the forces with which algae cells adhere to surfaces and move on them. How can cells adhere to surfaces and move on them? This is a question that was investigated by an international team of researchers headed by Prof. Michael Hippler from the University of Münster and Prof. Kaiyao Huang from the Institute of Hydrobiology (Chinese Academy of Sciences, Wuhan, China).

Scientists develop novel approach to acquire fluorescence lifetime images

Fluorescence microscopy is widely used in biochemistry and life sciences because it allows scientists to directly observe cells and certain compounds in and around them. Fluorescent molecules absorb light within a specific wavelength range and then re-emit it at the longer wavelength range.
