TransFix Stabilisation of Circulating Tumour CellsCaltag have developed a specific TransFix® Vacuum Blood Collection Tube for Stabilising Circulating Tumour Cells (CTCs) in blood samples. The number of CTC populations present in patient blood is very low, therefore the usefulness of CTC assessments depends upon accurate cell counts and the corresponding analysis of molecular targets. The natural degradation of blood samples can mean these rare populations are lost. TransFix® stabilises blood samples at the time of collection and has been shown to significantly extend the integrity of cells within the samples allowing for downstream enrichment and enumeration of CTCs.
