There is an antibody called Y-Ae, generated by Rudensky/Janeway, which
recognizes a peptide from the I-E alpha chain complexed to the I-A(b)
molecule, and another called 30-2 generated by Morkowski/Rudensky, which
recognizes a peptide from murine invariant chain bound to I-A(b).  I
believe there is also an antibody against the SIINFEKL/K(b) complex.
