A representative neighbor-joining (NJ) tree constructed based on HCV E1 domain of 20 clones derived from 9.1 kb LRP product, which was amplified using mixed serum from samples LIV19 and LIV23. As expected, all clones are clustered into two groups, LIV19 and LIV23. There is no contradictory clustering for each clone in trees constructed with other seven domains, indicating the lack of LRP-mediated recombination.
