Frequently Asked Questions

Question 1:
Could you help us with the best way to prepare it for in vivo i.p. injections?

Answer:
It can be dissolved in 4% DMSO/corn oil at 3 mg/ml clearly.

Question 2:
How to solve the problem that it didn't dissolve up to 10mM in DMSO at room temperature?

Answer:
The solution can be heated up to 50 degrees to help dissolve it. Besides, sonication (with a probe sonicator) also greatly helps with this compound.

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).
