An immunoglobulin has two heavy chain and two light chain connected by disulfide bond. It mainly helps in immune defense. It is a glycoprotein. IgG is a major class of immunoglobulin. Horse IgG has different subclasses, IgG2a, IgG2b, IgG2c, IgG1 and IgG(T). Compared to other IgG molecules, IgG(T) has more carbohydrate content. In healthy individuals, total IgG is dispersed equally between circulating plasma and interstitial fluids.
Horse IgG is a plasma B cell derived antibody isotype defined by its heavy chain. IgG is the most abundant antibody isotype found in horse serum. IgG crosses the placental barrier, is a complement activator and binds to the Fc-receptors on phagocytic cells. The level of IgG may vary with the status of disease or infection.
Immunogen
Purified horse IgG
Application
Anti-Horse IgG (whole molecule)-Peroxidase antibody produced in rabbit has been used in:
enzyme-linked immunosorbent assay (ELISA)
HeV soluble G
indirect ELISA (HeVsG iELISA)
Biochem/physiol Actions
Equine IgG antibodies mainly regulate mucosal and systemic immunological responses and thereby, provide protection against disease-causing pathogens such as Streptococcus equi, and the horse flu virus. Horse IgG may also function to control the advancement of EHV-1 infection .
Immunoglobulin G (IgG) participates in hypersensitivity type II and type III.

Viperidae snakes are the most important agents of snakebites in Brazil. The protein composition of snake venoms has been frequently analyzed by means of electrophoretic techniques, but the interaction of proteins in venoms has barely been addressed. An electrophoretic technique
Upstream open reading frames (ORFs) are frequently found in the 5'-flanking regions of genes and may have a regulatory role in gene expression. A small ORF (named cohL here) was identified upstream from the copAB copper operon in Xanthomonascitri subsp.
Mass-vaccination against COVID-19 is still a distant goal for most low-to-middle income countries. The experience gained through decades producing polyclonal immunotherapeutics (such as antivenoms) in many of those countries is being redirected to develop similar products able to neutralize SARS-CoV-2

Pythiosis, whose etiological agent is the oomycete Pythium insidiosum, is a life-threatening disease that occurs mainly in tropical and subtropical countries, affecting several animal species. It is frequently found in horses in Brazil and humans in Thailand. The disease is

Scorpionism is responsible for most accidents involving venomous animals in Brazil, which leads to severe symptoms that can evolve to death. Scorpion venoms consist of complexes cocktails, including peptides, proteins, and non-protein compounds, making separation and purification procedures extremely difficult
