I want to add 200 uM to my cells.

At the end of the day, I don't know what concentration and how much I need to get 200 uM of Leupeptin.
Here is the information regarding Leupeptin

Can anyone help out?
Sorry, I am not exactly a math genius right now.

Would greatly appreciate it!

Thank you greatly

What salt do you have (i can’t access the link)? Find the formula weight of the leupeptin salt you have, divide 2mg/ml by the fw (that gives you the molar concentration of the stock, remember that 2mg/ml=2gm/l). Then figure the dilution of that to 200 uM (c1v1=c2v2).
