Last Month's Most Accessed Feature: Viagra cheats exposed by TLC

Health supplements in some countries are frequently adulterated with PDE5 inhibitors, such as sildenafil (Viagra) or unapproved analogues. Researchers from Tianjin University of Science and Technology in China used a combination of TLC and Raman spectroscopy for the rapid identification of these pharmaceutical products in supplement samples.

Mixed-mode chromatography (MMC), which combines the properties of ion-exchange chromatography (IEC) and hydrophobic interaction chromatography (HIC), is increasingly used for the purification of various proteins, such as medicinal antibodies. Scientists from Mannheim University of Applied Sciences and Roche Pharmaceuticals’ Munich site developed equations to predict the elution of a bispecific antibody from an MMC column.

The diversity of current mass spectrometry methods and software tools has led to multiple arrays of data that are not readily comparable. Researchers from Harvard Medical School and the Dana-Farber Cancer Institute in Boston have reported on the latest version of their multiplierz software, which aims to provide a common platform for mass spectrometry proteomic data.
