Here. we present a modified in vitro end-joining (EJ) assay to quantify EJ capacity. accuracy as well as pathway switch to alternative end-joining (Alt-EJ) or single strand annealing (SSA). A novel transformation assay was established to specifically measure circular repair products. https://www.diegojavierfares.com/flash-offer-A-D-EJ-123-Newton-Compact-Balance-Scale-120-x-0-001-g-hot-grab/
