Vitamin B12, also called cobalamin, is a water-soluble vitamin that is involved in the metabolism of every cell of the human body: it is a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is particularly important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the maturation of developing red blood cells in the bone marrow.
This kit is a product based on indirect-competitive ELISA, which is fast, easy, accurate and sensitive compared with common instrumental analysis.

Product Info
DBCO-C3-PEG4-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro diagnostic workflows
Simultaneous isolation of both host DNA and microbial DNA (universal protocol)
Eliminates PCR inhibitors including humic acids
Fully compatible with Norgen’s Stool Nucleic Acid Collection and Transport Tubes
High quality DNA for sensitive downstream applications including PCR, qPCR, sequencing and microarray
This kit provides a convenient and rapid method to isolate total DNA from fresh, frozen and preserved stool samples, including those preserved using Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx (Cat. Dx45660). The universal protocol conveniently allows for the isolation of total genomic DNA from all the various microorganisms and host cells found in the stool sample simultaneously. The kit removes all traces of humic acids and other inhibitors using Bead Tubes and a combination of chemical and physical homogenization and lysis, without the need of any phenol-chloroform extractions. A simple and rapid spin column procedure is then used to further purify the DNA with high yields and molecular weights of up to 50 kb plus. The purified DNA is of the highest quality and is fully compatible with all downstream applications such as PCR, qPCR, NGS and microarrays since all humic acid substances and other PCR inhibitors are removed during the isolation process.
