Abstract

ENSAIO PARA A PRODUçãO DE CIRCOVìRUS PORCINO. A presente invenção refere-se a métodos para a determinação do título viral de uma cultura de células hospedeiras de animal infectadas com um circovírus. Os métodos baseados em FACS da invenção podem incluir a determinação da viabilidade das células hospedeiras no sobrenadante em um sobrenadante de meio de cultura celular e daquelas células que permanecem aderidas a um suporte sólido. Detectar e medir o percentual de células que expressam os antígenos virais de ORF1 e ORF2 pode determinar a carga viral das células hospedeiras cultivadas. O rendimento do vírus pode ser estabelecido pela detecção e medida de ambos os antígenos nas células sobrenadantes, por exemplo, 5 a 7 dias a partir de quando as células hospedeiras são transferidas para um meio livre de soro. Os métodos da invenção podem fornecer dados quantitativos rápidos. Isso permite o monitoramento em andamento repetido da produção viral através do período de incubação e pronta seleção do ponto de coleta mais apropriado.
