Polysorbate
Description
This is a polysorbate 80 sample demoing the PolyMatch software. This software contains PEGS, methyl-PEGS, fatty acid linked PEGS, polyisosorbide with and without fatty acids, and polysorbate with and without fatty acids (up to four fatty acids). A project in collaboration with David Weil from Agilent Technologies.
We are currently looking for collaborators to better understand MS/MS fragmentation patterns, and with interesting applications!
The raw data is available at MassIVE (MSV000092669) using the following ftp link ftp://massive.ucsd.edu/MSV000092669/ which also includes Polysorbate 20 data for comparison.
