Individual proteins identified with world’s tiniest ruler
Nanosized caliper that can identify individual proteins could ‘do for proteins what next-generation sequencing did for DNA’
Researchers have invented nano-sized calipers to identify individual protein molecules, which could make it easier to find trace proteins in biological samples. ‘We want to do for proteins what next-generation sequencing did for DNA,’ says Wesley Wong from Harvard University, US, who developed the technique with his colleagues.
