- Western blot analysis of Carcinoembryonic Antigen (CEA) was performed by loading 20 µg of BxPC-3, HeLa, and HepG2 whole cell lysates per well and 5 µL of PageRuler Plus Prestained Protein Ladder (Product # 26619) onto a 4-20% Tris-Glycine polyacrylamide gel. Proteins were transferred to a nitrocellulose membrane using the G2 Blotter (Product # 62288), and blocked with 5% Milk in TBST for 1 hour at room temperature. CEA (with varying degrees of glycosylation) was detected at ~77-180 kD using a CEA monoclonal antibody (Product # MA5-14675) at a dilution of 1 µg/mL in 5% milk in TBST overnight at 4C on a rocking platform, followed by a goat anti-mouse IgG HRP secondary antibody (Product # 31430) at a dilution of 1:10,000 for at least 30 minutes at room temperature. Chemiluminescent detection was performed using SuperSignal West Pico substrate (Product # 34080).

- Immunofluorescent analysis of Carcinoembryonic Antigen (CEA, green) in BxPC-3 cells. Cells were fixed with 4% paraformaldehyde, permeabilized with 0.1% Triton X-100, and blocked with 0.3% BSA in PBS, each for 15 minutes at room temperature. Cells were stained with a CEA monoclonal antibody (Product # MA5-14675) at a dilution of 10 µg/mL in blocking buffer for 1 hour at room temperature, and then incubated with a goat anti-mouse IgG Superclonal™ secondary antibody, Alexa Fluor® 488 conjugate (Product # A28175) at a dilution of 1:1000 for 1 hour at room temperature. Nuclei (blue) were stained with Hoechst nuclear stain. Images were taken on a Thermo Scientific ToxInsight Instrument at 20X magnification.

- Flow cytometry analysis of Carcinoembryonic Antigen (CEA) on BxPC-3 cells. Cells were harvested with 0.25% Trypsin-EDTA and stained with a CEA monoclonal antibody (Product # MA5-14675) at a dilution of 10 µg/mL (pink histogram), or with a mouse isotype control (black histogram) at a dilution of 10 µg/mL in PBS + 5% FCS. After incubation of the primary antibody for 1 hour on ice, the cells were stained with a goat anti-mouse IgG secondary antibody, DyLight 488 conjugate (Product # 35502) at a dilution of 1:40 for 1 hour on ice. A representative 10,000 cells were acquired for each sample.

- Figure 3 Immunoblotting of Affimer precipitated CEA. Monoclonal anti-CEA and anti-His 6 tag antibodies were used to probe ( A ) the CEA protein and ( B ) Affimers, respectively from the pull-down complex. Yeast SUMO-10 binder was used as a control Affimer. Commercial CEA from Abcam was used as positive control and cell lysates from HEK 293 as negative control. LoVo M and C are samples from medium and cell lysates, respectively. Full-length blots are presented in Supplementary Fig. S3 .

Monoclonal anti-CEA and anti-His 6 tag antibodies were used to probe the pulled-down ( A ) deglycosylated CEA and ( B ) Affimers, respectively. Yeast SUMO-10 binder was used as a control Affimer and RNase B was used as non-specific analyte. Digested CEA was used as a reference to the pulled-down CEA in blotting. Full-length blot of Fig. 4B is presented in Supplementary Fig. S3 .
