In Vitro

3-AP shows anti-proliferative activity with IC₅₀ values of 1.3, 1.6 µM for L1210, L1210/HUr cells, respectively^[1].
3-AP (5, 10, 15, 20, 30 mg/kg; i.p.; twice daily for six consecutive days) significantly increases in life span were observed with each dosage employed and long term survivors^[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.
