Toxoplasma gondii IgM µ-capture ELISA

Enzyme immunoassay for the qualitative determination of IgM class antibodies against Toxoplasma gondii in human serum or plasma.

INTENDED USE:The Toxoplasma gondii IgM µ-capture ELISA is intended for the determination of IgM class antibodies against Toxoplasma gondii in human serum or plasma (citrate, heparin). For research use only - Not for use in diagnostic procedures.

GENERAL INFORMATION:The immunoenzymatic determination of specific IgM-class antibodies is based on the ELISA (Enzymelinked Immunosorbent Assay) µ-capture technique. Microtiterplates are coated with anti-human IgM-class antibodies to bind the corresponding antibodies of the sample. After washing the wells to remove all unbound sample material, horseradish peroxidase (HRP) labelled antigen is added. This antigen-conjugate binds to the captured specific IgM antibodies. In a second washing step unbound conjugate is removed. The immune complexes are visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue reaction product. The intensity of this product is proportional to the amount of specific IgM antibodies in the sample. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint colour. Absorbance at 450/620 nm is read using an ELISA Microtiterplate reader.
