A METHOD FOR A LARGE SCALE VIRUS PURIFICATION

A method for purifying a virus comprising at least the following steps: a) obtaining a virus-containing fluid, b) providing a pre-formed linear density gradient of a given range X%-Y% (v/w) (X being the lower limit and Y being the upper limit) in a centrifuge rotor having a capacity of at least 4L,...

description A method for purifying a virus comprising at least the following steps: a) obtaining a virus-containing fluid, b) providing a pre-formed linear density gradient of a given range X%-Y% (v/w) (X being the lower limit and Y being the upper limit) in a centrifuge rotor having a capacity of at least 4L, at least 6L, at least 8L, or at least 10L, c) adding the fluid to the pre-formed linear density gradient, d) centrifuging so as to separate the virus from contaminating impurities, and e) collecting the fractions comprising the purified virus, wherein the linear part of the gradient encompasses the density percentage corresponding to the percentage at which the virus to be purified will migrate. La présente invention concerne un procédé de purification d'un virus comprenant au moins les étapes suivantes : a) obtenir un fluide contenant un virus, b) fournir à une tête à centrifuger, ayant une capacité d'au moins 4 L, d'au moins 6 L, d'au moins 8 L, ou d'au moins 10 L, un gradient de densité linéaire préformé d'une plage donnée allant de X % à Y % (v/p) (X étant la limite inférieure et Y étant la limite supérieure), c) ajouter le fluide au gradient de densité linéaire préformé, d) centrifuger de manière à séparer le virus des impuretés contaminantes, et e) recueillir les fractions comprenant le virus purifié, la partie linéaire du gradient comprenant le pourcentage de densité correspondant au pourcentage auquel va migrer le virus devant être purifié.
