Intended use

This monoclonal antibody enables specific detection of human IgG in immunoassays such as ELISpot, FluoroSpot, and ELISA.

Serum/Plasma samples

Recommendation

MT145 is recommended as capture mAb in ELISA in combination with detection mAb MT78 (product code 3850-9A) for determination of human total IgG. The antibody is also suitable as capture mAb in ELISpot and FluoroSpot for enumeration of B cells secreting IgG subclasses.

Learn how to combine Mabtech’s antibodies for human IgG ELISA and ELISpot. Adjust the setup to detect either total IgG or antigen-specific IgG. Different antibody combinations of monoclonal antibodies have been selected for the detection of the human IgG subclasses in ELISA and ELISpot. There is no cross-reactivity to human IgA1, IgA2, IgM, and IgE.

 

Application guide: ELISA

The human IgG ELISA can be adapted to detect antigen-specific IgG or the total IgG in serum or plasma samples.

Antigen-specific IgG

Capture: Antigen
Detection mAbs: MT78/145, biotin or MT78, ALP

Make sure to check out how researchers have used Mabtech's human IgG ELISA, ELISpot, and FluoroSpot kits in everything from vaccine development to SARS-CoV-2 research. You can find it all in our Publication database!

Find out which analyte combinations we have evaluated in T cell FluoroSpot and which combinations are affected by capture effects or not. 

What is a capture effect?

When capture antibodies with different specificities are coated together, capture of one cytokine may affect the secretion of other cytokines. This is usually more pronounced when studying T cell responses with polyclonal stimuli compared to antigen-specific responses. Capture effects are seldom a problem and can often be counteracted by addition of an anti-CD28 antibody.

IgG

Analyte description

Immunoglobulin G (IgG) is the most abundant Ig isotype in serum, making up approximately 80% of all serum immunoglobulins. In humans, there are four subclasses of immunoglobulin G, with the highest serum concentrations of IgG1 followed by IgG2, IgG3, and IgG4. In mice, the IgG subclasses are defined as IgG1, IgG2a/c, IgG2b, and IgG3. The IgG molecule consists of two heavy and two light chains (κ or λ), resulting in a molecule with two arms for antigen binding. High levels of IgG antibodies are induced following the initial IgM response in a typical immune response to antigens.
