Objective To predict the B-cell epitope for lipopolysaccharide-binding protein (LBP) antigen. Methods Using biotic software and network servers
the secondary structure of LBP was predicted
and the surface properties of LBP
such as hydrophilicity
flexibility
accessibility and antigenicity
were analyzed. Then the average antigen index (AI) was calculated by using Wu’s method. Results Many distinct antigenic epitopes on LBP were identified: AI of sequence 247-260 (FKGEIFHRNHRSPV) on LBP was 0.040 7
significantly higher than that of other sequences. AI of sequence 370-379 (LPSSSKEPVF) and sequence 303-325 (ITDDMIPPDSNIRLTTKSFRPFV) was 0.033 6 and 0.029 5
respectively. Sequence 247-260 was the prevalent antigen epitope of Bcell on LBP. Conclusion The B-cell epitopes of LBP is predicted successfully.
