I had assumed that John Ferbas was using HUMAN cells since he used W6/32 
which we use as a strictly human antibody, but of course it cross reacts 
with mouse cells (when they are grown in bovine serum).  The method just 
suggested is of course the classical approach, but using mabs is somewhat 
easier than getting good cell lines at least sometimes.
