HEK-293T Hücrelerinde Homolog Olmayan Uç Birleştirme ve Homolog Rekombinasyon Etkinliğinin GFP Tabanlı Raporlayıcı Sistemler Kullanılarak Analizi

Executive Industry Relevance

Quantitative assessment of nonhomologous end joining (NHEJ) and homologous recombination (HR) efficiency in HEK-293T cells enables mechanistic de-risking of DNA repair pathways during early discovery. The use of extrachromosomal GFP-based reporter assays accelerates comparative analysis across multiple cell lines, supporting predictive confidence in target validation and pathway interrogation. This approach informs risk-adjusted portfolio decisions by clarifying DNA repair capacity and pathway dependencies.
