For investigation of signal transduction mechanisms, this was an essential tool for studying the activity of tyrosine kinases and phosphatases. The antibody can either be used to probe...

Astrobiology is interested in how ecological communities develop in extreme environments to enable us to draw out some principles for the development of life on other planets, so a long-term ecological perspective is important. It strikes me that if we...
