In Vivo (Add solvents to the product individually and in order.)
Homogeneous suspension
CMC-NA
≥5mg/ml Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.
Clear solution
5%DMSO 40%PEG300 5%Tween80 50%ddH2O

Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 4.950mg/ml (9.24mM) Taking the 1 mL working solution as an example, add 50 μL of 99 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil

Validated by Selleck labs. Should you need adjustments to this formulation, contact our sales team for custom testing.

 0.820mg/ml (1.53mM) Taking the 1 mL working solution as an example, add 50 μL of 16.4 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description PFI-2 is a potent, selective, and cell-active lysine methyltransferase SETD7 inhibitor with Ki (app) and IC50 of 0.33 nM and 2 nM, 1000-fold selectivity over other methyltransferases and other non-epigenetic targets.
Targets
SETD7
(Cell-free assay)		 SETD7
(Cell-free assay)
0.33 nM(Ki) 2 nM
In vitro (R)-PFI-2 shows 500-fold more inhibitory activity against human SETD7 than its enantiomer, (S)-PFI-2. In a cellular environment, through direct interactions with SETD7, affects Yes-Associated protein localization and phenocopies Setd7 genetic deletion on Hippo pathway signaling.
