Taenia solium - IgG ELISA

Cysticercosis is caused by larval cysts of the tapeworm Taenia solium and is a major cause of adult onset seizures in most developing countries. Diagnosis is based on imaging findings, but in many cases it is not conclusive for the diagnosis. Serological assays has an important place on the final diagnosis of the disease. The ELISA kit hs shown appropriate performances for the serological screening of cysticercosis.

This product is manufactured by Bordier Affinity Products in Switzerland and distributed in Germany exclusively by Milenia Biotec.

The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Taenia solium cyst soluble antigens. Specific antibodies in the sample will bind to these antigens and washing will remove unspecific antibodies. The presence of parasite specific antibodies is detected with a Protein A – alkaline phosphatase conjugate. A second washing step will remove unbound conjugate. Revealing bound antibodies is made by the addition of pNPP substrate which turns yellow in the presence of alkaline phosphatase. Color intensity is proportional to the amount of Taenia solium specific antibodies in the sample. Potassium phosphate is added to stop the reaction. Absorbance at 405 nm is read using an ELISA microplate reader. The test can be performed with automatic systems, but this must be validated by the user.
