Product:            Rabbit anti-HA2 CD domain (Influenza virus H5 subtype) polyclonal IgG antibody.
 
Catalog#:         182404.
 
Description:     This polyclonal IgG antibody was generated in rabbits with the consensus HA2 CD sequence of                                 influenza virus H5 subtype [IENLNKKMEDGFLDVWTYNAELLVLMENERTLDFHDSNVKNLYDKV 
                         RLQLRDN​] fused to a natural nanoparticle protein carrier of E. Coli (Ref 1). The CD, also                                         known as long alpha helix (LAH), is a major part of the HA2 subunit of HA molecule and                                         constitutes the central part of HA stem (Ref 2 and see Figure). The IgG antibody was purified                                 from immune serum with protein A column.
 
Host species:    Rabbit.
 
Specificity:       HA2 of influenza H5 subtype. It has a low level of cross reaction with HA2 of H1 subtype, but not
                         H3 subtype or B virus. 


Amount:           100 µg IgG in 100 µl PBS containing 0.05% sodium azide as the preservative.
 
Storage:            2-8°C for routine use and -20°C for long-term storage.
 
Applications:
                         ELISA – quality tested with recombinant HA (H5N1) antigens with a titer ≥1:20,000.
                         Immunoblot – quality tested with inactivated influenza antigens and recombinant HA (see
                         Figure).
