What is the best antibody for pan-keratin detection in human cell lines (is it AE1+AE3)? Also, does skim-milk powder contain keratin?

I am wanting to detect human keratins by Western blotting and look for changes in levels of each keratin. I wanted to find out what the best pan-keratin antibody is available to quantify changes...
