In Vitro

IACS-9571 shows excellent cellular potency with EC₅₀ of 50 nM. IACS-9571 (1 μM) has potent activities against a panel of 32 bromodomains. IACS-9571 is a selective dual TRIM24/BRPF1 inhibitor (K_d = 1.3/2.1 nM) with 9- and 21-fold selectivity against BRPF2 and BRPF3, respectively. IACS-9571 does not interact with the BET sub-family of bromodomains, displaying greater than 7,700-fold selectivity versus BRD4(1, 2) relative to TRIM24^[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.
