Is free cytosolic GFP fluorescence excluded or reduced in the endomembrane system (ER, Golgi, lysosomes)? Why or why not?

As soluble, untagged GFP is not membrane bound and doesn't contain targeting or signal sequences, one might expect it to be synthesized by free ribosomes and not bound ribosomes. That would mean...

Are plasma protein free cysteines truly free?

free as in unreacted sulfydryls, not free as in speech, nor free as in beer :) I am working with an 80 kDa plasma protein with 5 cysteines, 2 of which are in a disulfide bridge. There are a lot...
