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

95% sensitivity, 98% specificity
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 CellG3 assay reagent for the measurement of endo-cellulase (endo-1,4-β-glucanase) contains two components; 1) 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-D-cellotrioside (BCNPG3) and 2) thermostable β-glucosidase. The benzylidene blocking group prevents any hydrolytic action by the β-glucosidase on BCNPG3. Incubation with an endo-cellulase generates a non-blocked colourimetric oligosaccharide that is rapidly hydrolysed by the ancillary β-glucosidase. The rate of formation of 2-chloro-4-nitrophenol is therefore directly related to the hydrolysis of BCNPG3 by the endo-cellulase. The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH 9.0).
Please note that a new assay kit (K-CellG5) is now available for the measurement of endo-cellulase. The CellG5 reagent contains a cellopentaose core and exhibits vastly improved sensitivity for some cellulases. In addition, the exchange of the benzylidene blocking group in CellG3 for 3-keto-butylidene in CellG5 improves the substrate’s water solubility significantly, allowing for a reduction in the concentration of DMSO required in the assay. As DMSO is known to inhibit certain cellulases, this is another benefit in using CellG5. Megazyme now recommends the use of K-CellG5 for all assays for the measurement of endo-cellulase.

Propargyl-PEG14-t-butyl ester consists of a propargyl group and a t-butyl protected carboxyl group. The propargyl group can be used in copper catalyzed Click Chemistry to yield a stable triazole linkage with azides. The t-butyl group can be hydrolyzed in acidic conditions. The hydrophilic PEG units help the molecule to have better solubility in aqueous environment. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
