In a toxicology study, the EC concentrations are reported as as units of "log μM," for example 0.49 log μM. How do I translate that into simple μM concentrations?
In this case, is the base of the log 10? Or is it μM, meaning 1 x 10^-6?
Using this log calculator (https://www.rapidtables.com/calc/math/Log_Calculator.html), if I put the base as 10 and the number as 0.49, the result I get is -0.30980392. How can the concentration be a negative number?
Whereas, if I interpret this to mean that the base of the log is μM, and I write μM as 0.000001 (which is 1 x 10^-6), then the result I get is 0.0516339867 μM.
you need to de-log by taking (exp) of this value and you will have the original uM value without the log.
Hi Leena, thanks for answering, but I am not sure if I understood your answer correctly. To see if I understood you correctly, could you tell me what the answer to this problem is? What is 0.49 log uM in uM?
