제목 The release of albumin from implantable wafers
초록 It has become important to target research in order to develop the sustained and controlled delivery systems for peptides or proteins. Implantable wafer for drug delivery using the biodegradable synthetic polymers has been widely investigated over the past several years because it has been considered as one of the most convenient methods to capture drug inside administration forms. We here describe the approach to evaluate the release behaviors of bovine serum albumin (BSA) from the implantable wafers prepared by MPEG-PCL diblock copolymers with different compositions.
Figure 1 shows releasing profiles of BSA from the wafers. As relative MPEG segment increased or relative PCL segment in diblock copolymers decreased, the release amount of BSA increased. The wafers exhibited the controlled release profiles with a dependence on changing of MPEG-PCL diblock copolymer compositions, even though they had initial burst.

In conclusion, we confirmed the possibility of MPEG-Polyester diblock copolymers as protein carriers for implantable wafer possessing many advantages such as simple manufacture, long-term delivery, and controlled release.
