RI-2 is a reversible RAD51 inhibitor, with an IC 50 of 44.17 μM, and specifically inhibits homologous recombination repair in human cells. In Vitro RI-2 (7a) is a reversible RAD51 inhibitor, with an IC 50 of 44.17 μM. RI-2 specifically inhibits homologous recombination repair in human cells. RI-2 (150 μM) induces a significant sensitization of cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Form:Solid IC50& Target:IC50: 44.17 μM (RAD51)
