Fig. 7.
Total release of (A, B) native GFP, (C, D) supercharged negative GFP and (E, F) supercharged positive GFP was compared to formulations containing 25 μM L-histidine (His; squares), 25 μM sodium acetate (Ace; diamonds) or 30 mg/mL polysorbate 20 (PS20; triangles) over 24 h. Hydrogels were composed of (A, C & E) 1 mg/mL Col1/0.5 mg/mL HA or (B, D & F) 1 mg/mL Col1. (E & F) Inset magnifies initial release of GFP-pos. Mean +/− standard deviation. Data is reformulated from Fig. 3, Fig. 4, Fig. 5, Fig. 6 with corresponding n numbers.
