IgGs are glycoprotein antibodies that modulate several immune responses. Rat IgGs against target proteins are often used as primary antibodies in various research applications. Thus, secondary anti-rat IgG conjugated to a detectable substrate is a useful tool for the analysis of target proteins. Anti-Rat IgG (whole molecule)-Peroxidase antibody binds all rat immunoglobulins. IgG (immunoglobulin γ) is a monomeric antibody containing a γ Fc region as a part of heavy chain, which is linked to the Fab arm through a hinge region. It is the most abundant serum antibody and constitutes to 70% of the total immunoglobulins.
Immunogen
Purified rat IgG
Application
Anti-Rat IgG (whole molecule)-Peroxidase antibody is suitable for use in ELISA and immunoblot at 1:5000 dilutions.
Lysates generated from primary cells isolated from lymphoid organs of P. monodon shrimp were analyzed by western blot using HRP-conjugated goat anti-rat as the secondary antibody at a 1:4000 dilution.
Biochem/physiol Actions
IgG (immunoglobulin γ), upon epitope binding, mediates the activation of classical complement pathway. Interaction between the host cell membrane and IgG antibody results in type II hypersensitivity reaction. Decreased serum levels of IgG contributes to common variable immunodeficiency, thus making the individual easily prone to infections.

The yellow head virus is a positive-sense, single-stranded RNA virus that causes significant mortality in farmed penaeid shrimp. This study sought to isolate and characterize the receptor protein used by the virus to gain entry into Penaeus monodon Oka (lymphoid)

In sera from patients with autoimmune liver diseases, e. g. primary sclerosing cholangitis (PSC) and autoimmune hepatitis, anti-neutrophil cytoplasmic antibodies (ANCAs) can be found. Until now, no animal model of ANCA induction in liver disease has been described. In this
Respiratory syncytial virus (RSV) is a massive medical burden in infants, children and the elderly worldwide, and an effective, safe RSV vaccine remains an unmet need. Here we assess a novel vaccination strategy based on the intradermal delivery of a
Nearly one third of the eukaryotic proteome traverses the secretory pathway and most of these proteins are N-glycosylated in the lumen of the endoplasmic reticulum. N-glycans fulfill multiple structural and biological functions, and are crucial for productive folding of many
In eukaryotes, RNA species originating from pervasive transcription are regulators of various cellular processes, from the expression of individual genes to the control of cellular development and oncogenesis. In prokaryotes, the function of pervasive transcription and its output on cell
