In Vitro

Anti-cancerOthers

Anti-cancer

Top1-IN-3 (48 h) selectively inhibits the growth of SKOV-3 ovarian cancer cells with an IC₅₀ of 16.49 μM, whereas the IC₅₀ in A549 and MRC-5 cells is >50 μM^[1].

Others

Top1-IN-3 (Compound 8b) (3.2 μM; 1-5 min) inhibits hTOP1-mediated DNA relaxation, with activity higher than that of CPT^[1].
Top1-IN-3 (0.1-100 μM; 30 min) modulates P-gp-mediated transport in MDCK-MDR1 cells, with an EC₅₀ of 12.30 μM^[1].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
