(a) Silver stained SDS/PAGE gel demonstrating a representative selection of tumor associated proteins prior to and after encapsulation. A relative paucity of bands between 46K and 66.4K was noted in NP-released samples with an apparent stacking at 97.4K. Staining was more intense in the lane containing release sample from the lyophilized version of NP. Both post-encapsulation samples were obtained from equal amounts (5mg/lane) of 80K PLGA/0.5% PVA NP. Lane 1: Lyophilized lysate; lane 2: Soluble lysate; lane 3: Pre-encapsulation lysate (3.25μg); lane 4: MW ladder. b) Western blot of membrane probed with anti-p53 antibody. Lane 1: post-encapsulation release sample (80K PLGA); lane 2: lysate (pre-encapsulation); lane 3: 46kDa labeled band from MW ladder.
