Table 2. Cross-recognition results for six different Melan-A-specic CTL clones in a chromium release assay: the logarithm of the relative functional avidity of the ELX analogs to ELA is given.

Seqa	Melan-A-specic CTL clones
	203-R7		25-R3		203-R2b		203-R1		203-R3		25-R35
ELA	0.00c	0.00d	0.00	0.00	0.00	0.00	0.00	0.00	0.00	0.00	0.00	0.00
ELS	−0.59	0.14	−0.41	0.13	−0.07	0.00	−0.01	0.10	−0.99	0.01	−2.44	0.50

^aThe P1-P3 peptide sequence of the ELX analog.

^bOnly one experiment was done with the 203-R2 clone.

^cThe logarithm of the relative functional avidity of the ELX analogs compared to ELA was calculated as log10(EC50_ELA/EC50_ELX). A value of −1.00 means that the molar concentration of the ELX peptide needs to be 10 times higher than ELA to achieve the same activity, i.e. 50% of maximal lysis. The average over the independent experiments for each CTL clone is given.

^dStandard deviation. By the denition of the score, the standard deviation for ELA is zero.
