IgA antibody
Biotinylated Goat anti Human IgA antibody used for the evaluation of human IgA responses to pneumococcal challenge by ELISA with subsequent detection by alkaline phosphatase conjugated streptavidin (STAR6B) and p-nitrophenyl phosphate.
Image caption:
IgG and IgA responses to whole cell 23F or 6B pneumococci following 23F or 6B challenge, respectively. ELISAs were performed using 23F or 6B pneumococci as targets to measure specific IgG (A, C and E) and IgA (B, D and F) titers in serum (A and B), NW (C and D) and BAL (E and F). Values shown are the mean antibody titers (of triplicates), pre and post 23F (n = 7) or 6B (n = 8) challenge (x-axis). *represents statistical significance between pre- and post-inoculation antibody titers.

Biotin conjugated Goat anti Human IgA antibody (205008) used to evaluate virus specific IgA responses in human samples by ELISA.
Image caption:
Recovery of influenza specific nasal IgA is not affected by posting samples. Adult volunteers, had nasal samples collected by flocked swab. Samples were either processed directly from the nose or posted via the internal mail system. Having processed the samples they were analysed for H1N1 (a) or H3N2 (b) specific nasal IgA by ELISA. n = 6.

Antibody Quality and 
Unrivaled 
| Goat anti Human IgA antibody recognizes the heavy chain of human IgA as demonstrated by ELISA and Flow cytometry. IgA is the major catagory of antibody present in mucosal secretions and acts as a first line of defense against inhaled or ingested pathogens at the mucosal interface. IgA is also present in serum where it acts to eliminate pathogens via interaction with FcαR, also known as CD89. (Woof et al. 2004). Biotinylated Goat anti Human IgA antibody (205008) has been cross-adsorbed against human IgD, IgG and IgM to ensure class specificity. |
