Yersinia enterocolitica IgA ELISA

Enzyme immunoassay for the qualitative determination of IgA class antibodies against antigens of the 70 kb virulence plasmid of Yersinia enterocolitica in human serum or plasma (citrate, heparin).

INTENDED USE:The Yersinia enterocolitica IgA ELISA is intended for the determination of IgA class antibodies against antigens of the 70 kb virulence plasmid of Yersinia enterocolitica in human serum or plasma (citrate, heparin). For Research Use Only – Not for Use in Diagnostic Procedure.

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.
