Figure 1

EpCAM positive human breast carcinoma cells were isolated from a heterogeneous sample of human cells using the Tumor Cell Isolation Kit, human, an LS Column, and a QuadroMACS™ Separator. Subsequently, the unseparated fraction and the negative fraction were cultured for seven days in expansion medium (90% RPMI-1640, 2mM L-Glutamine, 10% FBS, 100 U/mL penicillin, and 100 U/mL streptomycin). After fixation, cells were stained using antibodies specific for vimentin (red), labeling fibroblasts, and EpCAM (green), labeling tumor cells. Cell nuclei were stained with DAPI (blue).

human breast carcinoma cells were isolated from a heterogeneous sample of human cells using the Tumor Cell Isolation Kit, human, an LS Column, and a QuadroMACS™ Separator after the tissue was dissociated using the Tumor Dissociation Kit, human and the gentleMACS™ Octo Dissociator. The cells were fluorescently stained with CD326 (EpCAM)‑VioBlue

Detailed product information

Background information

The Tumor Cell Isolation Kit, human has been designed for the enrichment of untouched human tumor cells from primary specimens. During the growth phase in vivo, tumor tissue is vascularized and infiltrated by cells of non-tumor origin, including heterogeneous lymphocyte subpopulations, fibroblasts, and endothelial cells.
The level of infiltration is highly dependent on multiple factors like tumor subtype, growth rate, and affected organ site. However, even when these factors are constant, the amount and composition of infiltrating cells are highly variable, which makes accurate molecular downstream analyses difficult.
The contaminating non-tumor cells lead to hybridization of non-tumor cell derived mRNA molecules to probes on microarrays and a significant reduction of sensitivity caused by measurement of irrelevant signals during next-generation sequencing or proteome analysis. In addition, the culture of human tumor cells is frequently hampered by fibroblasts overgrowing the target cells. For optimal results, the Tumor Cell Isolation Kit, human should be used in combination with the Tumor Dissociation Kit, human (# 130-095-929) and gentleMACS™ Dissociators.
