Characterization of MPC-n (IgG). A Schematic for the synthesis of MPC-n (IgG). B Size of IgG and MPC-n (IgG) measured by dynamic light scattering. C Representative transmission electron micrographs of MPC-n (IgG). Scale bar = 50 nm. D FT-IR spectra of free IgG, polymer gels without IgG, and MPC-n (IgG) after lyophilization. E Release of MPC-n (IgG) of different pH (6.5 and 7.4) measured by dynamic light scattering. F Flow chart showing IgG and MPC-n (IgG) administration and experimental design
