	The first step in developing a succesful tagged protein is to have an 
antibody against the TAG that has "No" or "very Low" background in your 
system i.e. Tomato. You may have to buy the antibody and test it on a 
Western.

	The second point is that the TAG should be accesible to the antibody 
once the tagged protein has been produced (Assuming native folding and 
cellular localization).  As you can imagine there is no way to predict 
this. Therefore you have to do the experiment.
