Peptides enriched in tumor tissue after selection for tumor-homing AAV

asingle letter code; only peptides occurring repetitively or sharing common sequence motifs are shown; shared amino acid patterns are highlighted in colored letters
bcharge pattern of amino acid side chains: +, positively charged; − negatively charged; x, uncharged polar; y, nonpolar.
cobserved frequency relative to overall number of sequenced clones
dpathway B subsequent to 2 rounds of in vitro selection as in pathway A

a. 采用氨基酸单字母编码；仅展示重复出现或共享共同序列基序（sequence motif）的肽段；共享的氨基酸特征模式以彩色字体高亮标注。
b. 氨基酸侧链电荷标识规则：+ 代表带正电荷的侧链；− 代表带负电荷的侧链；x 代表不带电荷的极性侧链；y 代表非极性侧链。
c. 观测频率以总测序克隆数为参照基准。
d. 途径B参照途径A的体外筛选流程，经2轮体外筛选后得到的实验组别。
