INTRODUCTION

Animals are consistently exposed to environmental factors that penetrate the body from multiple sites, such as the respiratory and digestive tracts, or through damaged skin. Penetrating antigens can activate the humoral immune response which produces anti-antigen immunoglobulins to protect the host. Immunoglobulins are classified by their isotypes which differ by biological properties, functional locations, and ability to deal with different antigens. The main isotypes are summarized below:

1) Immunoglobulin A (IgA) plays a critical role in mucosal immunity and is found in the mucous membranes, especially the respiratory and gastrointestinal tracts, as well as in saliva and tears.
2) Immunoglobulin E (IgE) is involved in allergic reactions and is found in the lungs, skin, and mucous membranes.
3) Immunoglobulin G (IgG) is the most abundant isotype and is found in blood and extracellular fluids. In mice, IgG is categorized into four subtypes: IgG1, IgG2a, IgG2b, and IgG3.4) Immunoglobulin M (IgM) is the first isotype produced in a humoral immune response and is found mainly in the blood and lymph fluid. Total immunoglobulin isotype levels correlate with health or pathological conditions such as hypo- or hyper-gammaglobulinemia, and acute or chronic infections (1-5).

In addition, total immunoglobulin levels are often analyzed relative to antigen-specific antibody levels to evaluate immune function in patients and animal disease models. Chondrex, Inc. provides mouse total immunoglobulin isotype ELISA kits for IgA, IgE, IgM, and IgG, as well as IgG subtypes: IgG1, IgG2a, IgG2b, and IgG3, along with antigen-specific antibody ELISA kits, such as autoantigens (ssDNA and dsDNA), dietary proteins (collagen and OVA), and bacteria (E. coli, LPS and S. aureus). These total immunoglobulin detection ELISA kits are also suitable for quantifying monoclonal antibody and polyclonal antibody isotypes and/or subtypes, as well as establishing reliable methods for monitoring antibody production and quality control.
