BSA cleaved by Cu-MOF or trypsin.
(a) Results of SDS-PAGE performed on BSA (15 μM) incubated with Cu-MOF (0.99 mM) at pH 9.0 and 50°C. (b) BSA incubated with trypsin (40:1 w/w) and Cu-MOF (0.99 mM) at pH 7.4 for 20 min. Lane 1: BSA solution reacted at 70°C as control group (without trypsin and Cu-MOF). Lanes 2–3: BSA reacted with trypsin at 70°C and 37°C, respectively. Lane 4: BSA incubated with Cu-MOF at 70°C.
