Las reservas virales de cada uno de los virus producidos están constituidas por pases sucesivos en cultivo de células (EPC) del sobrenadante tomado 7 días después de la transfección (sobrenadante PO). Las células se infectan con dilución 1/100 del sobrenadante clarificado. Después de 3 pases, se retiran los sobrenadantes cuando la capa de células se destruye por el efecto citopático del virus; esto sucede habitualmente de 3 a 6 días después de la infección. Las reservas virales se titulan después por dilución limitante.
La Figura 3 muestra ejemplos de título viral de diversos virus recombinantes en cultivo de células EPC. Aunque el título viral para todos los virus recombinantes está en el mismo intervalo (108 UFP/ml), los virus recombinantes que comprenden tres unidades de expresión adicionales tienen un crecimiento más lento en comparación con el virus de tipo silvestre. En general se tarda seis días en obtener un efecto citopático completo en células EPC en lugar de tres días para el IHNV de tipo silvestre.
Se produjeron proteínas de interés usando los IHNV recombinantes enumerados en las Tablas I, II y III.
IHNV recombinante que expresa las proteínas estructurales del virus de la enfermedad del sueño
Se infectan células EPC con IHNV de tipo silvestre, IHNV-6KE1, IHNV-CapE3E2 o IHNV-E3E26KE1 a una MOI (multiplicación de infección) de 0,02 (0,02 UFP/célula). Las células se lisan 48 horas después de la infección, y los lisados se analizan por transferencia de Western usando un anticuerpo monoclonal dirigido contra la glucoproteína E1 de SDV.
Los resultados se muestran en la Figura 4: Carril 1: IHNV-E3E26KE1; Carril 2: IHNV-CapE3E2; Carril 3: IHNV-6KE1; Carril 4: IHNV de tipo silvestre.
IHNV recombinante que expresa la glucoproteína hemaglutinina (HA) de virus de la anemia infecciosa del salmón (ISAV)
Se infectan células EPC con IHNV de tipo silvestre o IHNV-HAISAV, como se ha descrito anteriormente. Las células se lisan 2 días después de la infección, y los lisados se inmunoprecipitan con anticuerpo monoclonal anti-HA y se analizan por transferencia de Western usando un anticuerpo policlonal dirigido contra la glucoproteína HA de ISAV.
Los resultados se muestran en la Figura 5: Carril 1: IHNV de tipo silvestre; Carril 2: IHNV-ISAV HA.
INHV recombinante que expresa la glucoproteína G del virus de la septicemia hemorrágica viral (VHSV) fusionada con una proteína indicadora
Se infectan células EPC, como se ha descrito anteriormente, con IHNV de tipo silvestre, IHNV-GVHSV, IHNV-GVHSV/LUCRR, IHNVGVHSV/EGFP, o con el sobrenadante de células EPC no infectadas (infectadas con simulación). Las células se lisan 2 días después de la infección, y los lisados se analizan por transferencia de Western usando un anticuerpo monoclonal dirigido contra la glucoproteína G de VHSV.
