Human IgA ELISpot kits
Pick the right ELISpot kit for Human IgA. Our kits differ in how you develop the signal – this page explains what those differences mean.
IgA ELISpot kits are also available for monkey, and mouse.
What differs between these kits
Which detection system
Available with Streptavidin-ALP or Streptavidin-HRP. You add the streptavidin conjugate as a second incubation after the biotinylated antibody, which amplifies the signal. Alkaline phosphatase (ALP) and horseradish peroxidase (HRP) perform equivalently, so that choice usually comes down to the substrate and reader you already work with.
Supplied without a plate, streptavidin conjugate, enough for 4 plates
About IgA
These Human IgA ELISpot kits target IGHA1 and IGHA2 (Homo sapiens).
IgA (Immunoglobulin A) represents only 10-15% of the total Ig molecules in serum but is the predominating Ig isotype in secretions and in the gastrointestinal and urogenital tract. The IgA found in secretions (secretory IgA or sIgA) is commonly a dimer with two IgA molecules joined by the J chain. Secretory IgA is the most important Ig isotype in mucous surfaces, the area of entry for most pathogens.
