Figure Lengend Snippet: H1975 or H1975-GFP cells were labeled with CellTracker™ Green CMFDA dye, and a cell suspension of 1000 cells/mL was made. 100 µL of this fluorescently labeled H1975 cell suspension (containing approx. 100 cells) were added to both 5 mL of healthy donor blood and each control well (total 3). The spiked blood sample was incubated for 30 min before processing through the different CTC isolation systems: CellMag™, EasySep™, RosetteSep™, Parsortix® PR1 and PX+. B) In order to compare the recovery rate of in-cassette staining between the PR1 and PX+ systems, a similar protocol was followed using unlabeled H1975 cells. The enriched cells captured in the cassette were fixed and stained using the Parsortix® PR1 with Alexa Fluor (AF)-conjugated antibodies against Cytokeratins (CK 4,5,6,8,10,13, 18 and 19) and EpCAM (AF488, green), Vimentin (AF546, yellow), CD45 (AF647, red), and Hoechst nuclear stain (blue).
Article Snippet: The EasySep™ Direct Human CTC Enrichment Kit (Catalog #19657, StemCell Technologies) along with the “Big Easy” Magnet (Catalog #18001, StemCell Technologies) was used in this study to enrich cancer cells spiked into whole blood.
