Fasciolosis is one of the most frequently encountered autochthonous helminthic infections in Central Europe. The immunodiagnosis of Fasciola hepatica infections is challenged by high serological cross-reacitivity with other (hepatic) parasitological infections encountered in Central Europe, such as alveolar echinococcosis, toxocarosis and ascariosis, but also other parasitic infections acquired during overseas travel. The SAP-2 recombinant antigen shows a high specificity, especially with patients with other parasitic infections. It is a suitable serological test for routine diagnosis of human fasciolosis, particularly if the results are supported by clinical history.
This product is manufactured by Bordier Affinity Products in Switzerland and distributed in Germany exclusively by Milenia Biotec.
Method/Platform
ELISA in microplate format
Range/Assay Sensivity
77% sensitivity, 98% specificity
Test Principle
The kit provides all the material needed to perform 96 enzyme-linked immunosorbant assays (ELISA) on breakable microtitration wells sensitized with Fasciola hepaticarecombinant antigen. Specific antibodies in the sample will bind to the antigen 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 Fasciola hepatica 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.

Includes pre-loaded beads for effective sample homogenization by bead beating (tubes are fully compatible with commercially available bead beating systems)
DNA preservation at room temperature over 2 years
Ship fecal samples at room temperature safely
Compatible with most DNA isolation methods
Norgen’s Fecal DNA Collection & Preservation Mini Tubes are designed for the rapid preservation of DNA from fresh fecal specimens. These tubes contain Norgen’s Fecal DNA Preservative in a liquid format. Moreover, each collection tube is preloaded with beads for effective sample homogenization in any commercially available bead beater equipment (e.g. MP Biomedicals’ FastPrep®-24). The user simply collects fecal samples into the tubes and mixes by shaking or vortexing until the feces is mixed well with preservative. The preservative prevents the growth of Gram-negative and Gram-positive bacteria and fungi, and also inactivates viruses allowing the resulting non-infectious samples to be handled and shipped safely. In addition, the preservative eliminates the need to immediately process or freeze samples and allows the samples to be shipped to centralized testing facilities at ambient temperatures. The components of the preservative allow the DNA in the samples to be preserved at room temperature for over 2 years.
This kit is highly suited to collection and preservation of fecal material from mouse, hamster, chinchilla, rabbit and more for microbiome studies and other applications.
DNA Isolation from Preservative
Fecal samples collected and preserved in Norgen’s Fecal DNA Collection and Preservation Mini Tubes are compatible with most fecal DNA isolation methods. Samples stored in the tubes have been used successfully with all of Norgen Biotek’s stool-based DNA isolation kits (please refer to Related Products table) and reagents.
