Human IgG4 ELISpot kits
Pick the right ELISpot kit for Human IgG4. Our kits differ in how you develop the signal – this page explains what those differences mean.
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 IgG4
These Human IgG4 ELISpot kits target IGHG4 (Homo sapiens, Gene ID 3503).
IgG (Immunoglobulin G) is the most abundant Ig isotype in serum, making up approximately 80% of all serum Immunoglobulins. In humans, there are four subclasses of IgG, with the highest serum concentrations of IgG1 followed by IgG2, IgG3, and IgG4. IgG4 cannot activate the complement system but binds well to Fc receptors.
