人Anti-Influenza virus B IgA ELISA试剂盒(ab108744)

Thank you for your patience. Unfortunately, these kits have not been tested with the virus strains you are using and also not with nasal swaps and we do not know if this would work. I also have an additional concern: I understand you want to detect IgA antibodies which are synthesized as response to a vaccination with Influenza antigens. We have no data or literature about that but is very unlikely that the body will create IgA antibodies. This kind of antibody is a response of the mucosa to contact with a pathogen. In case of a vaccination there is no mucosa contact and hence I believe the production of IgA antibodies is improbable unless the vaccination is being administered intra nasally. I am sorry that I could not provide you with a positive answer on this occasion and hope this information is nevertheless helpful.

Thank you for your inquiry. Ploease see the answer to your questions below: 1. For Influenza A IgA ELISA, ab108743, the wells are coated with purified Influenza A grade 2 antigens, strain Texas 1/77 (H3N2). For Influenza B IgA ELISA, ab108744, the wells are coated with purified Influenza B grade 2 antigens, strain Honk Kong 5/72. I can confirm that this ia a mixture of antigens and not only HA antigen. 2. I can confirm that the controls and cut-off control consists of positive human serum with preservative. Unfortunately, we do not sell human anti-influenza HA IgA serum at the moment. But I believe this is not necessary with this kit, since the control already consists of positive human serum. I hope this information is helpful and wish you good luck with your research.
