Stain-Free Imaging System

Criterion Stain Free™ imaging system is designed to enable stain-free detection and quantitation of proteins. The system consists of a new formulation of Criterion precast gels, a Criterion Stain Free imager, and Image Lab™ software. This system enables scientists to bypass the staining and destaining steps of SDS-PAGE and visualize protein samples after electrophoresis. In addition, the system captures digital images of gels to make record keeping easy and gel drying obsolete. Benefits of the system include: obtaining gel images in 2.5 minutes after electrophoresis; one-touch operation; equal or improved sensitivity compared to a Coomassie stain; compatibility with Western blotting and mass spectrometry; elimination of the gel-drying step; and no organic waste produced as a result of the process.

Scientifically Studying Ecstasy

MDMA (commonly known as the empathogen “ecstasy”) is classified as a Schedule 1 drug, which is reserved for compounds with no accepted medical use and a high abuse potential. Two researchers from Stanford, however, call for a rigorous scientific exploration of MDMA's effects to identify precisely how the drug works, the data from which could be used to develop therapeutic compounds.

Do you agree that ecstasy should be studied for its potential therapeutic benefits?
