Rapid Protein Screening
June 13, 2017 | Terry Sharrer
Biochemists at Penn State have developed a method for rapid screening of proteins (even in living cells) that relies on short bursts of laser light. Quoting directly: “The researchers are doing flow cytometry, but are using femto and pico-second lasers to inspect the proteins as they flow past in single file. The chosen proteins can then be separated from the rest. The lasers, cycling as fast as they do, do not heat up the samples quickly, so researchers can probe for the information they need before the sample heats up and the structure changes. They use a process called time-domain thermo-transmission which enables screening of proteins in milliseconds and does not kill living cells.” MORE
