IgG4 ELISpot kits
We make ELISpot kits for IgG4 in human. This page explains how they differ, so you can pick the one your experiment needs.
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.
About IgG4
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.
