During early drug discovery, the study of metabolism plays an essential role in determining which drug candidates move forward into development and later stages. Current methods for analysis to identify metabolic soft spots are through LC/MSn interpretation. The main challenge in this work has always been the structure elucidation of metabolites, and there have been a number of strategies developed to address these difficulties. Typically, the use of data dependent scanning has been the primary mode of data acquisition for structure elucidation, but in the past several years the use of MSe or All Ions Fragment (AIF) acquisition has become more prominent. Here we present a computational routine that automatically analyzes MSe/AIF data for LC/MSn based drug metabolism studies.

Multiplexing cell-based assays is possible using 3D culture models that are larger and more complex than monolayers
Real-time detection methods to measure live or dead cells provide much flexibility for multiplexing
All multiplexed assay combinations should be verified using appropriate controls for each 3D cell culture model.
Basic fibroblast growth factor (bFGF) is widely used in vitro for the maintenance and stimulation of a variety of cells. However, use of native bFGF in cell biology is limited by the fact that bFGF rapidly degrades at physiological temperatures. We have addressed this problem with an engineered form of bFGF, named Heat Stable bFGF (HS bFGF), which is stable at 37 degrees Celsius.
