I bought 100ug of IFN gamma from R&D systems, but all publications give "units/ml". There are no units listed on the data sheet or vial. How to convert?
So if your INFg is 2 x 104 units/ug on this list; you have a total of 2 x 106 International Units in 100 ug of IFN gamma. I am uncertain of "RU" vs "IU" however...
Each mg of interferon gamma-1b is approximately equivalent to 20 million international units (equivalent to the amount that formerly was expressed as 30 million units).
