"This new edition of Gene Targeting: A Practical Approach contains a remarkable collection of state-of-the-art protocols as well as thoughtful discussion of how to design a new mouse mutation and analyse the resulting phenotype to maximise the information gained. The techniques described for gene targeting in mouse ES cells, are equally applicable for gene targeting in other tissue culture cells, including human cells. The second edition describes additional genetic approaches for studying gene function in mice, including chimera analysis, gene trap (GT) approaches and powerful ways to combine gene targeting with classical genetics." "Gene Targeting: A Practical Approach (second edition) is a practical tool and information resource for scientists working on fundamental or applied aspects of gene targeting, ES cell manipulation, and analysis of mouse mutants. It will be invaluable to all researchers who wish to use the approaches for studies of gene function in cells or mice."--Jacket.
