Fig. 2From: Utility of dominant epitopes derived from cell-wall protein LppZ for immunodiagnostic of pulmonary tuberculosisIdentify the core sequence of candidate peptides during serum antibody reaction. A: Truncation assay on pep-LppZ-1 and pep-Lppz-13 peptides. N➡ indicates the truncation starts at the N terminal; C ➡ indicates the truncation starts at the C terminal. WT stands for wide type. Each letter means the amino acid was removed. Full-length blots are presented in Additional file 1: Figure S2Back to article page
