This document summarizes research on the interaction between Adeno-associated virus (AAV2) and its host cell receptor, AAVR. It describes AAV2 as a non-pathogenic virus that enters cells through receptor-mediated endocytosis without integrating into the host genome. It then discusses experiments expressing the AAVR protein in E. coli with His-tags to test binding with AAV2. Gel electrophoresis showed little difference between short and long induction times. Electron microscopy images of grids showed the AAV2 VLP-KL-His complex aggregated around the virus, indicating binding.
