Effect of PEG as a depletant to modulate IRI activity. (A) IRI activity of PVA85 (0.025 mg·mL–1) with PEG 4k; (B) PVA85 IRI activity with small molecule additives; Example cryomicroscopy images for (C) PVA85 (0.025 mg·mL–1), (D) PEG 4k (10 mg.mL–1), (E) PVA85 (0.025 mg·mL–1) + PEG 4k (10 mg·mL–1), (F) Schematic of depletion testing onto glass slides, and (G) Fluorescence microscopy and image analysis of Rhodamine-labeled PVA being depleted by PEG and NaCl. Average intensity values from minimum of 6 droplets. Scale bar = 100 μm. MGS = mean grain size.
