I don't understand the concept. I'd want to convert fg/ml of detection limit and linear range into U/ml. If I have a detection limit of 0.10 pg/mL, how do I convert that amount to U/ml?
. There is a conversion factor that has to be used. Every protein will have a different ng/ml to IU/ml conversion factor. Also, different suppliers may have their own method for defining a Unit. You need to refer to the insert provided by the supplier for more information on the conversion factor you may have to use.
I have attached a link below which may make it clearer.
