Patent

CA 2346927

The invention relates to a method for preparing an antibody-producing cell line capable of directed constitutive hypermutation of a specific nucleic acid region, comprising the steps of: a) screening a clonal cell population for V gene diversity; b) isolating one or more cells which display V gene diversity and comparing the rate of accumulation of mutations in the V genes and other genes of the selected cells; and c) selecting a cell in which the rate of V gene mutation exceeds that of other gene mutation.

La présente invention concerne une méthode de préparation d'une lignée cellulaire productrice d'anticorps, capable d'une hypermutation constitutive dirigée d'une région spécifique d'acide nucléique. Cette méthode consiste à: a) cribler une population cellulaire clonale pour une diversité des gènes V; b) isoler une ou plusieurs cellules présentant une diversité des gènes V et comparer le taux d'accumulation des mutations dans les gènes V et dans d'autres gènes des cellules choisies; et c) choisir une cellule dans laquelle le taux de mutation des gènes V est supérieur au taux de mutation d'autres gènes.
