Toxoplasma gondii IgA ELISA

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

INTENDED USE:The Toxoplasma gondii IgA ELISA is intended for the determination of IgA 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 antibodies is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique. Microtiterplates are coated with specific antigens to bind corresponding antibodies of the sample. After washing the wells to remove all unbound sample material a horseradish peroxidase (HRP) labelled conjugate is added. This conjugate binds to the captured antibodies. In a second washing step unbound conjugate is removed. The immune complex formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue reaction product. The intensity of this product is proportional to the amount of specific 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.
