quantifying the activity of a transcription factor - (Oct/21/2012 )
I am working with a transcription factor & i need to identify its activity among different time points. is there a method which can do that?
You probably need some sort of reporter assay based on a known downstream target. This is usually done with luciferase assays.
i am sorry i needed to be more specific... i need an in vitro test not an in vivo one.
Try in vitro transcription with rabbit reticulocyte lysate.
