Human IgG ELISA kits

Pick the right ELISA kit for Human IgG. Our kits differ in how you develop the signal – this page explains what those differences mean.

IgG ELISA kits are also available for equine, hamster, mouse, and rabbit.

What differs between these kits

Which detection system

Available with Streptavidin-ALP, Streptavidin-HRP, or One-step ALP. With a streptavidin conjugate you add a second incubation after the biotinylated antibody, which amplifies the signal. A one-step conjugate arrives attached to the antibody, so developing takes a single incubation. 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 IgG

These Human IgG ELISA kits target IGHG1, IGHG2, and IGHG3 (Homo sapiens).

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 immunoglobulin G, 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. The IgG molecule consists of two heavy and two light chains (κ or λ), resulting in a molecule with two arms for antigen binding. High levels of IgG antibodies are induced following the initial IgM response in a typical immune response to antigens.
