(I) (A) Vector map of the PASK protein optimized for bacterial expression 20-LPETGGLE-His8). (B) 12% SDS-PAGE and Western blot analysis using a horseradish peroxidase coupled to the anti-6XHis-tag antibody of the purified PASK protein. (C) Scheme of PASKE particle assembly. Transmission electronic microscopy (TEM) images and dynamic light scattering (DLS) for size distributions of MS@PASKE (D) and PASKE (E); (II) Cell interaction of PASKE, PEG, BSA, and MS@PASKE with human THP-1 and murine macrophages (RAsW 264.7); (III) functionalization of PASKE particles with the anti-GPIIb/IIIa scFv to impart a specific affinity to active platelets.
