Precise H1N1 swine influenza detection using stuffer-free multiplex ligation-dependent probe amplification in conformation-sensitive capillary electrophoresis.

The H1N1 influenza virus has spread worldwide to become pandemic. Here, we developed a new method to discriminate various types of influenza A, including H1N1, using stuffer-free multiplex ligation-dependent probe amplification based on a conformation-sensitive separation method, namely capillary electrophoresis-single-strand conformation polymorphism. Unlike conventional methods, our approach precisely detects five relevant gene markers permitting confirmation of infection.
