Detection and identification of point mutations in genomic DNA has proven increasingly important in biomedical research. A variety of methods for the analysis of single base substitutions have been proposed among which Single Strand Conformational Polymorphism (SSCP) quickly gained success due to its simplicity. In this work we present an analytical on-line tool which combines the ease of solid phase purification of amplified genomic DNA, the simplicity of SSCP and the significant potential advantages offered by capillary electrophoresis (CE).
