In Vitro

B026 (0-5 μM; 12 h; cancer cell lines) has antiproliferative activity^[1].
B026 (0-5 μM; 6 h; MV-4-11 cells) exhibits inhibitory effects on H3K27Ac expression^[1].
B026 (0-5 μM; 12 h; MV-4-11 cells) targets the cellular p300 protein and increases the thermal stability of p300 protein in a dose-dependent manner^[1].
B026 (0-1 μM; 24 h; MV-4-11 cells) decreases the expression of MYC, which a key oncogenictranscription factor that is regulated by superenhancer regions containing p300/CBP^[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.
