aNY-ESO-1 expression at the RNA level was assessed
by semiquantitative RT-PCR.
bNY-ESO-1 expression at the protein level was assessed
by IHC using monoclonal antibody ES121 to NY-ESO-1. Scoring: 0,
no positive cells; 1, rare and scattered positive cells; 2, <
or = 50% positive cells; 3, >50% positive cells; nd, not done.
Interpretation: pos, positive; neg, negative.
