Horse Immunoglobulin G (IgG) is the predominant antibody isotype in equine serum, playing a central role in the adaptive immune response by recognizing and neutralizing pathogens such as bacteria, viruses, and toxins. IgG is critical for long-term immunity, mediating pathogen clearance through opsonization, complement activation, and antibody-dependent cellular cytotoxicity. Measuring IgG levels in horses provides insight into their immune status, particularly in young foals, where passive transfer of maternal antibodies through colostrum is essential for protection against early-life infections.
The horse IgG ELISA (enzyme-linked immunosorbent assay) enables the quantitative assessment of IgG concentrations in serum, plasma, or colostrum. In research settings, this assay is used to study equine immunology, vaccine efficacy, and the development of immune responses to infectious agents. It can also be applied in studies of maternal antibody transfer, immune system maturation in foals, and the characterization of antibody responses in experimental models of disease or immunotherapy.
In clinical settings, horse IgG ELISAs are primarily employed to evaluate immune competence and detect failure of passive transfer (FPT) in neonatal foals, a condition associated with increased susceptibility to infections and poor survival rates. Additionally, measuring IgG levels helps monitor the immune status of adult horses, guide vaccination strategies, and assess responses to therapeutic interventions such as hyperimmune plasma administration. This makes the assay a practical tool for both preventive and diagnostic veterinary medicine.
