Frequently Asked Questions

Question 1:
how to reconstitute the inhibitor for in vivo studies?

Answer:
It can be dissolved in 5% DMSO/corn oil at 5 mg/ml as a clear solution for injection. For oral administration, this compound dissolved in vehicle 30% PEG400/0.5% Tween80/5%Propylene glycol, at 30mg/ml is a suspension and can be used.

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration _(start) x Volume _(start) = Concentration _(final) x Volume _(final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

*When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).
