Target Background

Immunoglobulin G (IgG) is an antibody that protects the body from infections, it can bind to viruses, bacteria and fungi. It is the most abundant antibody found in blood, lymph fluid, cerebrospinal fluid and peritoneal fluid and is essential in the humoral immune response. IgG uses agglutination to immobilize pathogens and allows phagocytic immune cells to recognize the pathogen by using opsonization. It can do this because it is a monomeric immunoglobulin made of two heavy chains and two light chains, making up two antigen binding sites. IgG is highly variable due to its composition of amino acids in the terminal portion. The C terminal is used for binding with the cell membrane, the complement system and allows it to pass through the placenta, thus providing protection to the fetus, which no other immunoglobulin can do. Thanks to the abundance and specificity towards antigens, IgG is the principal antibody used in immunological research and clinical diagnostics, making it a great option for ELISA. IgG is retained in the body for long periods of time, the longevity in serum makes it useful for immunization. Detection of IgG is used for indicating prior infection and vaccination.

Typical Data

ELH-IGG was used to quantify total plasma IgG levels in rhabdomyosarcoma patient samples to normalize anti-FGF8 autoantibody measurements at diagnosis. Figure adapted from Poli et al., OncoImmunology, 2022.


ELH-IGG was used to quantify human IgG recovery from diluted human serum following purification with polyVIM material. Figure adapted from Lei et al., Journal of Chromatography A, 2020.


ELH-IGG was used to quantify IgG concentrations in supernatants of hepatocellular carcinoma cell lines, demonstrating that HCC cells secrete IgG with higher levels observed in highly metastatic lines. Figure adapted from Yi et al., OncoImmunology, 2015.


ELH-IGG was used to measure biologically active IgG released over 7 days from poly(ε-caprolactone) microspheres formulated with different excipients. Figure adapted from Erdemli et al., Materials Science and Engineering C, 2015.

Customize This Human IgG ELISA

We manufacture our ELISAs in-house, so we can build a custom version for your study.

  • Post-translational modifications (PTMs): Detect modified IgG, including phosphorylation, acetylation, S-nitrosylation, S-acylation, oxidation, lactylation, sumoylation, ubiquitination, nitration, carbamylation, and more
  • Sample types: Validation in your matrix using samples you provide, such as CSF, urine, saliva, lysates, or exosomes
  • Also available: More sensitive platforms such as Simoa® and NexaTag®, multiplex panels, bulk lots, and other species when suitable reagents exist

Feasibility varies by target and modification, and we’ll tell you upfront what’s achievable.
