Patent Images
1. A method of preparing a genomic library for use in producing knockout targeting vectors comprising:
- a) preparing genomic DNA fragments of pre-selected sizes;
b) preparing a shuttle vector comprising inserting said genomic DNA fragments into a yeast vector, wherein the vector comprises;
i) a first bacterial origin of replication;
ii) a first bacterial selection marker;
iii) a first yeast origin of replication;
iv) a first yeast selection marker; and
v) a first mammalian selection marker;
c) introducing said vector into bacterial host cells to amplify said shuttle vectors in transformed bacterial host cells; and
;
d) arraying said transformed bacterial host cells into pools wherein the bacterial host cells comprise said shuttle vectors and wherein said pools comprise genomic fragments of pre-selected sizes.
