Switching off the centrifuge that was rather noisily separating some protein samples, he picked up the receiver and answered, "Poole here."

The instrument analyzed 1,000 protein samples per hour.

A protein sample is added to a solution of the dye in phosphoric acid and ethanol.

Mass spectrometry is currently the best method to adequately compare pairs of protein samples.

A protein sample is then layered on top of the gradient and spun at high speeds in an ultracentrifuge.

In 1954, he met Max Perutz; they began to study a new technique wherein X-rays would be passed through a protein sample.

You had me slice the shand to get a protein sample?

Other interference may come from the buffer used when preparing the protein sample.

Several conditions come into factor if a protein sample will crystallize or not.

This differs from the western blot because protein samples are not separated electrophoretically.
