Cryopreservation of CTCs for biobanking and sample logistics


This document is intended to guide the user through a method for working with frozen peripheral blood mononuclear cell (PBMC) samples obtained from whole blood collections. The freezing process enables the PBMC specimens to be retained for longer periods of time and shipped as necessary to the processing site. The protocol incorporates use of the IsoFlux System and the IsoFlux Circulating Tumor Cell (CTC) Enrichment Kit.
