calculation on inhibitor treatment - (May/16/2013 )

hello everybody,

i just want to ask if my calculation is correct. the paper mentioned that the optimum inhibitor concentration is 5 ug/ml. does that mean if i need to treat my cells in a petri dish and i have 10 ml of culture medium on it, i add 50 ug of inhibitor? if my stock is 10 mg/ml and my working is 5 ug/ml, should i add 5 ul of my inhibitor in my cells with 10 ml of culture medium? is this calculation correct?

thank you.

you are right....
