Mass spectrometry makes the clinical grade Posted: 03 Sep 2012 12:40 PM PDT A new mass spectrometry-based test identifies proteins from blood with as much accuracy and sensitivity as the antibody-based tests used clinically, researchers report. The head-to-head comparison using blood samples from cancer patients measured biomarkers, proteins whose presence identifies a disease or condition. The technique should be able to speed up development of protein-specific diagnostic tests and treatment. |
Waste cooking oil makes bioplastics cheaper Posted: 02 Sep 2012 07:25 PM PDT 'Bioplastics' that are naturally synthesized by microbes could be made commercially viable by using waste cooking oil as a starting material. This would reduce environmental contamination and also give high-quality plastics suitable for medical implants, according to scientists. |
