Catalog Number

Short Info
This ELISA kit is for the quantitative detection of IgG antibodies against parasites of Anisakidae family in human serum. Serology is an aid for diagnosis and cannot be used as the sole method of diagnosis.
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
97%
Test Principle
Specific antibodies in the sample bind to Anisakidae excreted/secreted larval antigens sensitized on microtiter plates. The presence of parasite specific antibodies is detected with a Protein A alkaline phosphatase conjugate.
Trichinellosis is caused by Trichinella spiralis, a parasitic nematode of pork, horse and wild animals. Humans can be infected by eating raw or undercooked meat from infected animals. Most infected people do not show any symptoms. However, in some cases, symptoms appear during intestinal stage (diarrhea and abdominal pain) and muscular stage (muscle pain, fever, edema). Diagnosis is based on signs and symptoms, but in many cases it is not conclusive for the diagnosis. Serological assays have an important place on the final diagnosis of the disease. The ELISA kit has shown appropriate performance for the serological screening of trichinellosis.

Test Principle
The kit provides all the material needed to perform 96 enzyme-linked immunosorbent assays (ELISA) on breakable microtitration wells sensitized with Trichinella spiralisexcreted/secreted (E/S) larval 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 Trichinella spiralis 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.

The Rapid Integrated Total Dietary Fiber Assay Kit method is validated under collaborative study (AACC Method 32-60.01, AOAC Method 2022.01, AOAC Method 2017.16, ICC Standard No. 185) and is recognized as a Type I Method by CODEX Alimentarius. The K-RINTDF method is the recommended one for the measurement of total dietary fiber in all foods that may or may not contain resistant starch. This method is updated to be more consistent with in vivo conditions in the human small intestine, i.e. a 4 h incubation time. Under these conditions more accurate measurement of resistant starch is obtained, including phosphate cross-liked starch (RS4). Use of higher enzyme concentrations ensures that resistant maltodextrins produced from non-resistant starch under the incubation conditions of the Integrated Total Dietary Fiber procedure (AOAC Methods 2009.01 and 2011.25) are no longer produced.
In this improved, rapid method, the incubation time with PAA + AMG is reduced to 4 h and the levels of both PAA and AMG are increased to ensure that resistant starch levels obtained with a set of control samples are consistent with ileostomy data. Under these conditions, the DF values obtained for most samples are the same as those obtained with AOAC Methods 2009.01 and 2011.25.
The dietary fiber fractions that are measured with this method are:
1. High Molecular Weight Dietary Fiber (HMWDF) including Insoluble Dietary Fiber (IDF) and High Molecular Weight Soluble Dietary Fiber (SDFP; soluble dietary fiber which is precipitated in the presence of 78% aqueous ethanol), and
2. Low Molecular Weight Soluble Dietary Fiber (SDFS; water soluble dietary fiber that is soluble in the presence of 78% aqueous ethanol).
Alternatively, IDF, SDFP and SDFS can be measured separately.
The enzymes used in this method are high purity and effectively devoid of contaminating enzymes active on other dietary fiber components such as β-glucan, pectin and arabinoxylan. They are supplied as freeze-dried powders; allowing the use of glycerol as an internal standard in the method.
