BSA-FITC-loaded microcapsules maintained their structure for at least 4weeks in the rat. The inflammatory response observed initially after injection declined over time. In conclusion, BSA-FITC-loaded microcapsules achieved sustained release of BSA-FITC, suggesting that microcapsules manufactured as ...
The primary structure of the released protein was analyzed using sodium dodecyl sulfate polyacrylamide gel electrophoresis. Poly(SA) and 20:80 (CPH:SA) microspheres were found to conserve the primary structure of the released protein and the secondary structure of the encapsulated protein, and showed...
SECONDARY STRUCTUREIn order to determine the efficacy of using polyanhydrides as a carrier for therapeutic proteins, the model protein bovine serum albumin labeled with fluorescein isothiocyanate (BSA-FITC) was encapsulated in microspheres of poly sebacic anhydride (poly(SA)), and random copolymers of...
