Tissue Dissociation for Metastasis Studies.

ABSTRACT

The main requirement for most metastasis-related applications is the conversion of solid tissue into a single-cell suspension. In theory, this suspension represents the diversity of cells present in the tissue, whether malignant or benign. We have found that cell viability, as measured by trypan blue staining or fluorescence-activated cell sorting (FACS), is critical for evaluating the success of the tissue-dissociation procedure. The recommended goal is at least 70% cell viability.
