The present status of genomic DNA subtraction techniques is reviewed.
The advantages and disadvantages of the widely-used methods of genome
subtraction are discussed. Using the kinetic model of subtractive hybr
idization developed by us previously (Sverdlov and Ermolaeva, 1993; Sv
erdlov and Ermolaeva, 1994), the application of genome subtraction to
various problems is analyzed. It is concluded that the technique shoul
d be further advanced based on subtraction of single-stranded DNAs. Th
is strategy would enable one to efficiently extract target sequences o
mitting the stage of genome simplification.
