Figure Lengend Snippet: Recovery rates of spiking experiments using (A) MCF‐7, (B) MDA‐MB‐231, and (C) SHP‐77 cells. Of each cell line, either 1, 10, or 100 cells were spiked into 7.5 mL of HD blood. Experiments were performed in triplicate. Twenty‐five Hs 578T (D), MDA‐MB‐231 (E), and MDA‐MB‐468 (F) cells were spiked into 7.5 mL of HD blood to analyze the impact of membrane functionalization with an anti‐EGFR antibody on cell lines with intermediate to high EGFR and low to high EpCAM expression. All error bars represent SD.
Article Snippet: After an initial washing step with 20 mL of 0.1% Tween/PBS, the filter, which had been functionalized with streptavidin, was incubated with 1 μg/mL biotinylated anti‐EpCAM‐antibody (R&D Systems) or 1 μg/mL biotinylated anti‐EGFR‐antibody (clone B1D8, Biotium) at RT for 1 h. Subsequently, the filter was washed with 20 mL of 0.1% Tween/PBS, and residual Tween was removed by washing the complete filtering system with 100 mL PBS.
