Capillary electrophoresis is an advanced analytical method used for the separation of molecules such as DNA, RNA, and proteins. This technique separates molecules based on their movement speeds within a capillary tube under the influence of an electric field. It is particularly effective in molecular diagnostics, especially in hematology-oncology, for detecting specific gene mutations and disease-specific biomarkers. This precise and fast method plays a critical role in the analysis of gene mutations, such as FLT3, while enhancing the accuracy of diagnostic tests.
