Northern vs Southern vs Western Blot - HELP!

DNA Binding Proteins = Southwest Blot

Just to add to this
Examples of DNA binding proteins that are commonly tested in USMLE are:
Steroid receptors, Thyroid hormones, Retinoic Acid receptors, and Transcription factors.

I don't get looking for a DNA binding protein??!!

How would the question scenario be?

Click to expand...

It would be something like this
" you did cDNA clone and made it to express a product then you used a DNA probe to label it, what product are we looking for?
a- glucagon
b- CFTR receptor
c- lysosomal enzyme
d- Zink finger
e- RAS protein

Although all the options are porteins but only Zink finger protein is a transcription factor that binds DNA and leads to increased gene expression
