But now, Stanford researchers have developed a super speedy technique to test millions of versions of a certain protein to see which one works best.
A Stanford news release explains:
The researchers call their tool µSCALE, or Single Cell Analysis and Laser Extraction.
The "µ" stands for the microcapillary glass slide that holds the protein samples. The slide is roughly the size and thickness of a penny, yet in that space a million capillary tubes are arrayed like straws, open on the top and bottom.
The microcapillary glass slide, roughly the size and thickness of a penny, holds the protein samples.
The power of µSCALE is how it enables researchers to build upon current biochemical techniques to run a million protein experiments simultaneously, then extract and further analyze the most promising results.
The system is easy to use with numerous applications, Baer said.
"Evolution, the survival of the fittest, takes place over a span of thousands of years, but we can now direct proteins to evolve in hours or days," Cochran said in the release.
