Detection of CTCs. After successful enrichment, CTCs can be detected by using various strategies. Exploiting protein expression pattern of CTCs by using immunocytochemistry/FACS. Molecular biology techniques either include detection of genetic mutations/translocations/methylation pattern using PCR assay or detection of specific mRNAs using RT-PCR. Function properties like specific proteins secreted can also be exploited for CTC detection
