MASP - a computer program for designing small combinatorial libraries
to be analyzed by mass spectrometry
- If you are working with combinatorial libraries and you have access to
an electrospray or MALDI-TOF mass spectrometer, here is the tool that
you need to shed light on your selection experiments. -
The Richert Research Group at Tufts University releases MASP, a computer
program calculating mass spectra, and searching structure space for
libraries that can be exhaustively analyzed by soft-ionization mass
MASP generates predictions for spectra independent of what your building
blocks are, provided that your library is of limited size. It screens
possible combinations of building blocks to identify libraries that show
minimal or no peak overlap in mass spectra. Now, you can analyze your
selection experiments on the level of individual components by acquiring
MASP runs on PC platforms featuring MS Windows 95/Windows NT. It should
no problem to compile the program under Windows 3.1(1)
