Scientists discover way to unboil egg
London, Jan 27
Researchers have managed to
unboil an ordinary boiled egg, and the results may have implications for
cancer treatments, biotechnology and a broad range of food production
processes, a British daily reported Tuesday.
"Yes, we have
invented a way to unboil a hen egg," The Independent quoted Gregory
Weiss, the lead author of the study supported by the US and Australian
governments, as saying.
A hard-boiled egg white represents proteins that have been cooked, tangled up and -- so it was thought -- irreversibly changed.
But
the scientists were able to force the proteins apart into their
untangled and reusable form. They added a urea substance to break down
the cooked egg and then applied a high-powered machine called a "vortex
fluid device" to achieve the result, the daily said.
"It's not
so much that we're interested in processing the eggs; that's just
demonstrating how powerful this process is," Weiss said.
"The
real problem is there are lots of cases of gummy proteins that you spend
way too much time scraping off your test tubes, and you want some means
of recovering that material."
Having an effective and quick
method for reusing wasted proteins could revolutionise a vast range of
scientific and manufacturing processes. For instance, cancer antibody
creation is done using expensive hamster ovary cells as they rarely
waste proteins. Thus, using the new process could make cancer research
and treatments cheaper.
The study was funded by the National
Institute of General Medical Sciences in the US and the Australian
Research Council, and published last week in the journal ChemBioChem.
