Figure 5. Cytotoxicity of non-cross-linked and cross-linked nanozymes in CATH.a neurons.

Figure 5

Cells were incubated for 24 h with either native SOD1, non-cross-linked SOD1/pLL10-PEG (Z=10), and SOD1/pLL10-PEG (Z=10) cross-linked using EDC/S-NHS in concentrations ranging from 1 to 200 μg/mL (SOD1). Cell viability was measured using a commercially available MTS assay kit and results are expressed as mean ± SEM (n = 3).
