Abstract

MÉTODO PARA DETERMINAR A RAZÃO DE PARTÍCULAS DE AAV E USO DO TEMPO DE RELAXAÇÃO. A presente invenção baseia-se, pelo menos em parte, na descoberta de que o tempo de relaxação de rotação magnética nuclear transversal T2 e a taxa de relaxação de rotação magnética nuclear transversal R2, respectivamente, de prótons de moléculas de água em uma solução aquosa compreendendo partículas virais dependem do estado de carregamento (cheio versus vazio) da partícula viral. Assim, um aspecto da presente invenção é um método para determinar a razão de partículas virais carregadas para partículas virais vazias em uma amostra, compreendendo as etapas de determinar um parâmetro de ressonância magnética nuclear (RMN) relacionado aos prótons das moléculas de água presentes em uma solução aquosa compreendendo uma mistura de partículas virais carregadas e vazias aplicando uma medição de RMN à solução, e determinar a razão de partículas virais carregadas para partículas virais vazias com o parâmetro de RMN determinado na etapa anterior com base em uma função de calibração.
