SEP derived from MCF10A and MDAMB231 cell lines. (A) Steps in the
discovery and validation of SEPs from these cell lines. (B) Total
of nine and five SEPs were validated using MRM in the MCF10A and MDAMB231
cell lines, respectively. (C) These 14 validated SEPs were targeted
in MCF10A and MDAMB231, while 12 SEPs found in both cell lines, two
SEPs, TASP1-SEP, and CAMD8-SEP, were specific to the MDAMB231 cell
line.
