Diazo Biotin-PEG3-alkyne is useful for introducing a biotin moiety to azide-containing biomolecules using Cu(I)-catalyzed Click Chemistry. The hydrophilic spacer arm provides better solubility to the labeled molecules in aqueous media. Diazo allows efficient release of captured biotinylated molecules from streptavidin using sodium dithionite (Na2S2O4). Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Sequentially isolate and purify total RNA and DNA from a single sample
Two column system: one for DNA and one for RNA
The RNA column is for the purification of total RNA including microRNA
No need to split the lysate, or to use phenol or precipitation methods
Rapid and efficient spin column procedure – it takes only 30 minutes
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provide a rapid method for the isolation and purification of total RNA and DNA sequentially from a single sample of cultured animal cells and tissues, blood, bacteria, yeast, or fungi. The lysate is passed over two columns: 1) a DNA column and 2) an RNA column. Total RNA of all sizes is purified, including microRNA. Both DNA and RNA are of the highest purity and yield.
These kits are ideal for researchers who are interested in studying the genome and transcriptome of a single sample, such as for studies of microRNA profiling, gene expression including gene silencing experiments or mRNA knockdowns, studies involving biomarker discovery, and for characterization of cultured cell lines. Norgen’s RNA/DNA Purification Kits are especially useful for researchers who are isolating macromolecules from precious, difficult to obtain or small samples such as biopsy materials or single foci from cell cultures, as they eliminate the need to fractionate the sample. Furthermore, analysis will be more reliable since the RNA and DNA are derived from the same sample, thereby eliminating inconsistent results. The purified macromolecules are of the highest purity and can be used in a number of different downstream applications
RNA/DNA Purification Kit (Spin Column)
Maximum column binding capacity of 50 μg for RNA and 20 μg for DNA.
RNA/DNA Purification Micro Kit (Micro)
The purified RNA and DNA fractions can be eluted in as little as 20 μL. Ideal for cell number inputs of 500,000 and as little as 5 cells. Maximum column binding capacity of 35 μg for RNA and 10 μg for DNA.

*Average Yield will vary depending upon a number of factors including species, growth conditions used, and development stage.
**Tissue inputs of up to 40 mg may be used, however for inputs greater than the recommended 25 mg, cross-contamination of the RNA and DNA fractions is possible.
Storage Conditions and Product Stability Store Proteinase K at -20°C upon arrival. All other solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 1 year after the date of shipment.
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.
