Take a look at these polyclonal antibodies against Influenza A/California/14/2009 (H1N1) which were recently developed. These antibodies do not crossreact with seasonal Influenza A H1N1. In addition we are offering antibodies against seasonal Influenza A H1N1: Influenza A/Brisbane/59/2007 (H1N1) and Influenza A/Georgia/20/2006 (H1N1). These antibodies do not crossreact with the Swine Flu virus Influenza A/California/14/2009 (H1N1).

The cross reactivities were tested by using strain-specific peptides. Tests with patient serum samples have not been conducted.

For developing these antibodies amino acid sequences of the Swine Flu virus Influenza A/California/14/2009 (H1N1) were identified, which are not present in Influenza A/Brisbane/59/2007 (H1N1) and Influenza A/Georgia/20/2006 (H1N1). Based on this analysis synthetic peptides were produced, which were used for the immunization of the rabbits.
