OICR-9429, a chemical probe, is high affinity WD repeat domain 5 (WDR5) inhibitor, competitively blocks WDR5 interaction with MLL protein via binding the central peptide-binding pocket of WDR5. OICR-9429 can suppress histone H3K4 trimethylation and can be used for the research of various cancers including non-MLL-rearranged leukaemia, colon, pancreatic, prostate cancer and bladder cancer (BCa) .

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

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.
