Relationships of viral sequences in P63 and LSC63 encoding peptides recognized after seroconversion of LSC63

Sequence relationship within the tested peptide (and within in the 5 amino acids flanking the tested peptide)a	No. of peptides (no. of HLA-B27-restricted peptides) that were:
	Located in pools recognized preseroconversion	Not located in pools recognized preseroconversion
P63 = LSC63 = peptide (P63 = LSC63)	0	1 (1)
P63 = LSC63 = peptide (P63 ≠ LSC63)	1 (0)	2 (0)
