Can ProA-immunoglobulins affinity be directly used for western?

I have a ProA tagged protein in yeast. I wonder if I can use yeast crude lysate in SDS PAGE, then visualize ProA by anti-mouse IgG-peroxidase conjugate as western analysis? Or I have to do it in a...

Do you need the CMV enhancer before the CMV promotor for a proper function of CMV on the gene that follows?

I'm a student and I have to produce a cell line with a knockin for the NRF2 gene with GFP. I have to put a promotor in front of the GFP because the gene will be too far away from the promotor of...
