AAV2 BR1 VP1 Sequence

AAV-BR1 is an AAV serotype 2 derived capsid variant containing the heptapeptide NRGTEWD. In contrast to wtAAV-2, this variant shows a high specificity for endothelial cells of the brain and spinal cord vasculature (CD31⁺ cells in the brain). Gene expression in other organs and cells (including brain parenchyma) was barely detectable. In addition to the high specificity, the AAV-BR1 variant shows a markedly increased transgene expression, which was found to be stable for an extended period of time (> 660 days).
