Name of Product

Fasciola hepatica – IgG ELISA

Catalog Number

AF 9650

Short Info

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 hepatica recombinant 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.

Introduction

This product is designed for purification of high-molecular-weight genomic or mitochondrial DNA from a variety of blood samples. High-quality DNA can be purified from sample types including whole blood, buffy coat, bone marrow, body fluids in as little as 25 minutes. The convenient, scalable purification procedure removes contaminants and enzyme inhibitors such as proteins and divalent cation, and purified DNA is ready for immediate use in sensitive downstream applications or for archiving.

Principles

Cells are lysed with ananionic detergent in the presence of a DNA stabilizer. The DNA stabilizer limits the activity of intracellular DNases and also DNases found elsewhere in the environment. RNA is then removed by treatment with an RNA digesting enzyme. Other contaminants, such as proteins, are removed by salt precipitation. Finally, the genomic DNA is recovered by precipitation with alcohol and dissolved in Buffer TE. Purified DNA typically has an A260/A280 ratio between 1.7 and 1.9, and is up to 200 kb in size. The DNA can be safely stored at 2-8°C, -20°C, or -80°C.

Advantages

• Safe – without phenol chloroform extraction
• Environment friendly – the reagents used are safe, non-toxic and without pollution
• High molecular weight – the molecular weight of genomic DNA is about 50-150kb
• High purity – the purified DNA has A260/280=1.8-1.9, A260/230=2.0-2.5
• Unlimited sample size – solution type operation, sample volume can be adjusted at will
• Cost performance – the most economical nucleic acid extraction technology

Storage and Stability

RNase Solution should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
