Figure 4.
The mean number of enriching cancer cells from the different ratios of cancer cells to PBMC by MNP-pan-ck.
Notes: When the ratio of cancer cells to PBMC is 1:5 × 106 (Group 3), the cancer cells are successfully enriched by MNP-pan-ck, and when the ratios of cancer cells to PBMC increases, the ability to enrich cancer cells is increased. The ratios of cancer cells to PBMC: Group 1, only PBMC; Group 2, 1:107; Group 3, 1:5 × 106; Group 4, 1:106; Group 5, 1:5 × 105; Group 6, 1:105; Group 7, 1:5 × 104; Group 8, 1:104.
Abbreviations: PBMC, peripheral blood mononuclear cells; MNP-pan-ck, MNPs coupled with pan-cytokeratin antibody.
