Anti-human IgG mAbs (MT78/145), biotin


Product specifications

Intended use

These monoclonal antibodies enable specific detection of human IgG in immunoassays such as ELISpot and FluoroSpot.

Serum/Plasma samples

Recommendation

MT91/145 are recommended as capture mAbs in ELISpot in combination with detection mAbs MT78/145 (product code 3850-6) for determination of total human IgG. The antibodies are also suitable as capture mAbs in FluoroSpot, as well as for antigen-specific ELISpot (detection with biotinylated antigen).

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.

Get inspired!

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.

The systems reactive with NHPs are either based on cross-reactive human kits or specifically developed monkey kits (NHP).

Cross-reactivity verification tests have been performed in ELISpot and/or ELISA by Mabtech and/or by others. Evaluations of assays with less solid evidence of cross-reactivity are shown as symbols within parentheses.

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.
