Encapsulation of Protein Using Porous PLGA Microspheres |
초록 |
Porous poly(D,L-lactide-co-glycolide) (PLGA) microparticles were demonstrated to be used for sustained delivery of protein by entrapping protein inside the inner pores. The porous PLGA microspheres with less than 10 um in size were prepared by electrospraying. Aqueous solutions containing fluorescein isothiocyanate-dextran or bovine serum albumin were penetrated into the inner pores and then the outer surface pores of the PLGA microspheres were closed using a solvent (dimethyl sulfoxide) for sustained release. Confocal microscopy image confirmed the presence of a large amount of the macromolecules inside the porous structure. Circular dichroism spectroscopy and release analysis of protein revealed that the protein was entrapped without denaturation and released in a sustained manner for over one month, respectively. |
