Need help with T-cell proliferation assay

OK, here's the scoop.  I am trying to do a T cell proliferation assay
where I immunize mice with a protein, remove the draining lymph
nodes, and culture the T cells with antigen.  Proliferation is 
measured by 3H thymidine incorporation.  If I use the protein as
the in vitro antigen, it works fine.  If I use a synthetic peptide
of the protein (one that works for other labs and for a prior grad
student in my lab) it doesn't work.  I'm really beating my head on
the wall with this and I'd appreciate any suggestions at all.
