To test the overall performance of the mCMx chips, we ran a 2 mL culture medium spiked with the pre-stained (CellTracker, Invitrogen, Waltham, MA, USA) primary cultured cells from an NTTg mouse primary tumor through each of the mCMx-mEpCAM chips or mCMx-HER2 chips. This evidence concerns the gene ERBB2 and neoplasm.
