Datasheet of PFI-4

Description: PFI-4 is a potent and selective and cell permeable BRPF1 bromodomain inhibitor (IC50 = 80 nM). Exhibits >100-fold selectivity for BRPF1 over a panel of other bromodomains including BRPF2 (BRD1), BRPF3 and BRD4. in vitro: Disrupts BRPF1 binding to histone H3.3. PFI-4 is a chemical probe that specifically binds to the bromodomain of BRPF1 with a Kd =13 nM as determined by ITC. It reduces recovery time in triple BRD cell construct in FRAP, inhibiting binding to tri-acetylated histone 4 (residues 1-21). It has much lower affinity for bromodomain 1 of BRD4 (Kd = >50 μM) and is selective for BRPF1 over BRPF2 and BRPF3. PFI-4 is potent in cells, with an IC50 value of 250 nM.

Handling: Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months. Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
