HBsAg deduced amino acid (aa) alignment. Comparison of aa substitutions in the Major Hydrophilic Region (MHR) of the HBsAg (aa 99-187), between sequences from OBI samples 001, 024, 038, 091, 097 and 123 and sequences from chronic HBV carriers subgenotype F3 from Colombia and Venezuela reported in GenBank. The aa were presented in single letter code. The lines indicate the regions of the sequences not included in the analysis. SueroCntP 11 corresponds to the positive control. At the top of the alignment, it is represented the MHR by rectangles between aa 107-165 of the HBsAg and the "a" determinant (aa124 to aa147). Red arrows indicate epitopes recognized by cytotoxic T lymphocytes.
