IgG3 ELISpot kits
We make ELISpot kits for IgG3 in 2 species. This page explains how they differ, so you can pick the one your experiment needs.
What differs between these kits
Which species they are for
Available for Human and Mouse. The species decides which antibody pair we supply, so it is the first thing to choose. Some kits are also validated on closely related species, so if you work in one we do not list here, check the reactivity on the product page.
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 IgG3
Immunoglobulin G (IgG) 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. In mice, the IgG subclasses are defined as IgG1, IgG2a/c, IgG2b, and IgG3. IgG3 binds to Fc receptors with high affinity and is a good complement activator.
