For native ChIP, 2–5 × 107 cells were collected and resuspended in 2 ml of ice cold buffer I (0.32 M Sucrose, 60 mM KCl, 15 mM NaCl, 5 mM MgCl2, 0.1 mM EGTA, 15 mM Tris [pH 7.5], 0.5 mM DTT, 0.1 mM PMSF, 1:1000 protease inhibitor cocktail [Sigma]). 2 ml of ice cold buffer I supplemented with 0.1% IGEPAL was added and placed on ice for 10 min. The resulting 4 ml of nuclei was gently layered on top of 8 ml of ice cold buffer III (1.2 M Sucrose, 60 mM KCl, 15 mM NaCl, 5 mM MgCl2, 0.1 mM EGTA, 15 mM Tris [pH 7.5], 0.5 mM DTT, 0.1 mM PMSF, 1:1000 protease inhibitor cocktail) and centrifuged at 10,000 × g for 20 min at 4°C with no brake. Pelleted nuclei were resuspended in buffer A (0.34 M sucrose, 15 mM Hepes [pH 7.4], 15 mM NaCl, 60 mM KCl, 4 mM MgCl2, 1 mM DTT, 0.1 mM PMSF, 1:1000 protease inhibitor cocktail (Sigma)) to 400 ng/ul. MNase (Affymetrix) digestion reactions were carried out on 100 µg or more chromatin using 0.9–2.8 U/µg chromatin in buffer A supplemented with 3 mM CaCl2 for 10 min at 37°C. The reaction was quenched with 5 mM EGTA on ice and centrifuged at 13,500 × g for 10 min. The chromatin was resuspended in 10 mM EDTA [pH 8.0], 1 mM PMSF, 1:1000 protease inhibitor cocktail and rotated at 4°C for 2–4 h. The mixture was adjusted to 500 mM NaCl, allowed to rotate for another 45 min and then centrifuged at 13,500 × g for 10 min yielding nucleosomes in the supernatant. 100 µg or more of chromatin was diluted to 100 ng/µl with buffer B (20 mM Tris [pH 8.0], 5 mM EDTA, 500 mM NaCl, 0.2% Tween 20) and pre-cleared with 60 µl 50% protein G bead (GE Healthcare) slurry for 20 min at 4°C. 1–2 µg of the pre-cleared supernatant (bulk nucleosomes) was saved for further processing. To the remaining supernatant, antibody was added and rotated overnight at 4°C. Immunocomplexes were recovered by addition of 100 µl 50% protein G bead slurry followed by rotation at 4°C for 3 h. The beads were washed three times with buffer B, and once with buffer B without Tween. For the input fraction, an equal volume of input recovery buffer (0.6 M NaCl, 20 mM EDTA, 20 mM Tris [pH 7.5], 1% SDS) and 1 µl of RNAse A (10 mg/ml) was added followed by incubation for one hour at 37°C. 100µg/ml Proteinase K (Roche) was then added and was incubated for another 3 h at 37°C. For the ChIP fraction, 300 µl of ChIP recovery buffer (20 mM Tris [pH 7.5], 20 mM EDTA, 0.5% SDS, 500 µg/ml Proteinase K) was added directly to the beads and incubated for 3–4 hrs at 56°C. The resulting Proteinase K-treated samples were subjected to a phenol-chloroform extraction followed by purification using a Qiagen MinElute column. For crosslinked ChIP, 2–5 × 107 cells were processed with the SimpleChIP Enzymatic Chromatin IP Kit (Cell Signaling) using the manufacturer’s recommendations. Unamplified bulk nucleosomes or ChIP DNA was analyzed using Agilent 2100 Bionanalyzer High Sensitivity Kit. The Bioanalyzer determines the quantity of DNA based on fluorescence intensity. Antibodies used for ChIP: mouse α-CENP-A monoclonal (15 µg, ab13939 (Abcam)); rabbit α-H3K9me3 polyclonal (10 µg, ab8898 (Abcam)); rabbit α-H3.3 polyclonal (17 µg, 09–838 (Millipore)).

As described previously [20 (link),25 (link)], EIA plates were coated with 10 μg/ml PGM type III (Sigma Aldrich) diluted in PBS and blocked with 5% Blotto in PBS/0.05% Tween 20. VLPs (0.5 μg/ml) were pretreated with decreasing concentrations of serum for 1 h before being added to the carbohydrate-ligand-coated plates for 1 h. Ligand-bound VLP was detected with rabbit anti-GI or -GII or -GII.4 VLP hyperimmune serum followed by anti-rabbit-IgG-HRP (GE Healthcare). All tested VLPs, except for GII.4.2012 and GII.4.2006b.P.D302, were components of the VLP cocktails used to immunize rabbits. Multivalent GII.4 VLP immunization resulted in broadly reactive serum that recognizes GII.4.2012 and GII.4.2006b.P.D302 [44 (link)]. Wash steps, Ab dilutions, and color development were completed as described above. All incubations were done at room temperature. The percent control binding was defined as the binding level in the presence of Ab pretreatment divided by the binding level in the absence of Ab pretreatment multiplied by 100. Blockade data were fit using sigmoidal dose–response analysis of nonlinear data in GraphPad Prism 6.02. EC50 values were calculated for sera that demonstrated blockade of at least 50% at the dilution series (40–20480) tested. Sera that did not block 50% of binding at the highest concentration tested were assigned an EC50 of 20 for statistical comparison.

Primary CD45+ immune cells, CD8+ tumor-infiltrating lymphocytes (TIL), and breast cancer cells were isolated from breast carcinoma samples obtained from biopsies or surgery. Briefly, tissues were cut into fragments of approximately 1 mm3 and then digested by enzymatic hydrolysate [DMEM (Gibco, #C11995500BT) supplemented with 10% FBS (Gibco, #10099141C), 1.5 mg/mL collagenase type I (Worthington, #LS004196), 1.5 mg/mL collagenase type III (Worthington, #LS004182), and 1.5 mg/mL hyaluronidase (Sigma-Aldrich, #H3506)] at 37°C with gentle agitation for 2 hours for cancer cell isolation and 1 hour for immune cell isolation. The dissociated tissues were resuspended and filtered through a 70-μm cell strainer to obtain single-cell suspensions. Thereafter, cancer cells were acquired through centrifugation at 250 × g for 5 minutes and purified using EpCAM Microbeads (Miltenyi Biotec, #130-061-101). To isolate immune cells, primary cell suspensions were centrifuged at 400 × g for 5 minutes and then CD8+ TILs were purified using CD8 Microbeads (Miltenyi Biotec, #130-045-201). CD45+ immune cells were isolated by fluorescence-activated cell sorting (FACS) using a BD Influx flow cytometer (see “FACS”). After isolation, cell purity was determined by flow cytometry (>95%).

The OSCs were fabricated with the conventional ITO/PEDOT:PSS/MBTR:PC71BM(w/w)/Au structure. Transparent ITO glass was critically cleaned in an ultrasonic bath using 2 mL hellmanex III solution in 200 mL hot water for 5 min. Next, the substrates were sequentially cleaned with DI water, acetone, and ethanol each for 10 min and dried in a vacuum oven. Further, the cleaned substrates were placed in UV–ozone equipment and exposed to UV–ozone for surface treatment for 15 min to remove the surface impurities and improve adhesion properties. We used solar-grade PEDOT:PSS (HTL Solar) for deposition of the buffer layer, which was filtered through a 0.45 μm polytetrafluoroethylene (PTFE) filter using a rubber-free syringe. The freshly prepared PEDOT:PSS solution was spin coated on the cleaned substrates at the rate of 4000 RPM for 30 s and annealed over a previously heated hot plate. Varying blend ratio (w/w) solutions were prepared by mixing MBTR and PC71BM in absolute chlorobenzene using a constant concentration of 30 mg/mL. The blend solution with 3% DIO additive for optimized devices was prepared in a volume ratio of chlorobenzene/DIO (97/3 v/v%) with a fixed active material concentration of 30 mg/mL. Next, the blend solution with and without DIO was spin-coated on ITO/PEDOT:PSS at a rate of 3000 RPM for 40 s and immediately baked at 80 °C for 10 min. Finally, the ITO/PEDOT:PSS/MBTR:PC71BM-deposited substrate was placed in a shadow mask, and a metal electrode layer of Au (gold) was thermally evaporated under a high vacuum of 1 × 10−6 Torr. The BHJ PV devices were fabricated at ambient temperature with an active area of 0.12 cm2.

The FRA was determined as described by García et al. [56 (link)]. Previously to determine FRA, plants were subjected to a pre-treatment for 30 min in plastic vessels with 50 mL of a nutrient solution without micronutrients, pH 5.5. Then they were transferred into 50 mL of a Fe (III) reduction assay solution for 1 h. This assay solution consisted of nutrient solution without micronutrients, 100μM Fe(III)-EDTA and 300 μM Ferrozine, pH was adjusted to 5.0 with KOH. The environmental conditions during the measurement of Fe (III) reduction were the same as the growth conditions described above. FRA was determined spectrophotometrically by measuring the absorbance (562 nm) of the Fe(II)-Ferrozine complex and by using an extinction coefficient of 29.800 M−1 cm−1. After that, roots were excised and weighed, and the results were expressed on a root fresh weight basis. Also, SPAD values (as a proxy of the chlorophyll concentration in leaf) were measured daily with a portable chlorophyllmeter (SPAD 502 Minolta Camera Co., Osaka, Japan).
