This submission contains the mass spectrometry files for the manuscript by Samavarchi-Tehrani et al. that describes the use of lentiviral delivery of BirA*-tagged transgenes into HeLa, BJ and MEF cells or in comparison to stably integrated transgene in Flp-In T-REx HeLa cell lines. This submission contains the mouse files from a set of 56 raw MS files and associated peak lists and result files, acquired on a TripleTOF 6600 spectrometer (AB SCIEX, Concord, Ontario, Canada) operated in Data Dependent Acquisition mode. Samples were generated by Payman Samavarchi-Tehrani. This massive submission contains the files for the mouse samples. Please see accompanying submission for the human samples. Raw files are deposited here in MassIVE. For questions, please contact Anne-Claude Gingras (gingras@lunenfeld.ca) or Payman Samavarchi-Tehrani (payman@lunenfeld.ca).
