Fluorescent Proteins

A team of scientists led by Daniela Dieterich from CalTech have developed a new fluorescent imaging technique to precisely trace the growth and migration of individual proteins in the brain. In a paper published in this month’s Nature Neuroscience, Dietrich’s team produced these stunning images of fluorescent neurons studded with nascent proteins:

Visualization of newly synthesized proteins in dissociated primary hippocampal neurons. (Dietrich et al, Nature Neuroscience, July 2010)

The scientists describe their technique in the paper’s abstract:

“This technique can be used to detect changes in protein synthesis and to evaluate the fate of proteins synthesized in different cellular compartments.”

  • Multilingual SEO is a way to increase online revenue and encourage global universal transparency.
    Backlinks could be inserted in multiple blogs or
    websites that really did not pertain to the site in question. Some SEO teams will provide you with hundreds of
    keywords to use in your website content, but that is not effective or efficient because many of those target words and phrases
    may not be used by many people.
