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
Propargyl-PEG4-5-nitrophenyl carbonate is heterobifunctional reagent with a propargyl group and nitrophenyl group. The propargyl group enales the formation of triazole linkage with azide compounds or biomolecules via copper catalyzed Click Chemistry. Nitrophenyl group is reactive towards the amino group of lysine by means of stable urethane linkages. The PEG units enhance the solubility of the molecule in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Magnetic bead nucleic acid purification technology uses nano or micron superparamagnetic material as the matrix, generally black ferric oxide or yellowish brown ferricoxide as the magnetic material. The surface of bead is coated with appropriate functional groups, which can adsorb nucleic acid. Magnetic beads commonly used for nucleic acids, containing carboxyl groups, hydroxyl groups, or silicon groups. Silicon-based magnetic beads are the most common, and its principle of adsorbing nucleic acid is consistent with the classical glass milk purification technology or glass fiber filter membrane purification method. Magpure particle is a kind of polydisperse fast speed silica magnetic beads. The core is ferricoxide, accounting for 50%, and the surface coating is silica, accounting for 50%. The product can be used for plasmid extraction, gel DNA recovery, product purification, genomic DNA and RNA extraction, and viral nucleic acid extraction.

Principle
Highsalt mediated binding: in the solution containing 2-4M guanidine isothiocyanate, Magpure particles can selectively recover DNA molecules, and impurities such as protein polysaccharides are not adsorbed.
Alcohol mediated binding: in the solution containing guanidine salt and alcohol (>25%), Magpure particles can selectively recover DNA/RNA molecules, and proteins and other impurities are not adsorbed.
After biological samples are treated with digestive solution or lysis Buffer, DNA/RNA is released from cells, organelles and protein complexes (ribosomes and nucleosomes) into reagents. After Magpure particles and binding solution are added, DNA/RNA is adsorbed to the surface of Magpure particles to form DNA/RNA bead complex. Under the action of the magnetic field, the magnetic beads are separated and collected, and the impurities such as protein are removed with the waste liquid. After two or three steps of further cleaning, the DNA/RNA magnetic bead complex is resuspended in sterilized water or TE buffer, and the DNA/RNA falls off from the surface of the magnetic beads, so as to achieve the purpose of purification.

The MagPure magnetic-particle technology combines the speed and efficiency of silica-based DNA purification with the convenient handling of magnetic particles. DNA binds to the silica surface of the magnetic particles in the presence of a chaotropic salt. DNA bound to the particles is then efficiently washed, considerably improving the purity of DNA. High-quality DNA is eluted. The automated purification procedure completely removes enzymes, nucleotides, and other contaminants and inhibitors. Purified DNA is suitable for direct use in downstream applications, such as sequencing and microarray analysis.

Principle
This product is suitable for extracting RNA from anticoagulant blood, lymphocytes, buffy coat, bone marrow, cultured cells and other samples. This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested by lysis buffer and protease, and RNA/DNA is released into the lysis buffer. Add binding solution and magnetic particles to adsorb RNA/DNA, while proteins are not adsorbed and removed. The particles adsorbed with DNA/RNA are washed with washing buffer to remove proteins and other impurities, then washed with ethanol to remove salt, and finally digested with DNase to remove DNA. RNA is recovered by adding binding solution, and finally the RNA is eluted with low salt buffer. The eluted RNA can be directly used for experiments such as RT-PCR,NGS and virus detection.
Advantages

Storage and Stability
DNase I should be shipped with ice pack or dry ice and stored at -20°C upon arrival. MagPure Particles N and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage(up to 8 weeks) at room temperature (15–25°C) does not affect their performance.The remaining kit components can be store at room temperature and are stable for up to 18 months under these conditions.
