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.

Bacillus cereus is a rod-shaped, gram-positive bacterium. Some strains of B. cereus cause foodpoisoning and other diseases such as keratitis. B. cereus grows at a wide range of temperature, from 4°C to 37°C. In fact, many foodborne illnesses caused by B. cereus are a consequence of improperly cooked or improperly stored food, including dairy products and meats. The majority of food poisoning by B. cereus could be divided into two types of symptoms – the emetic type and the diarrheal type, both of which are caused by the enterotoxin produced by the bacteria.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and protease. DNA is released into the lysate. After adding magnetic particles and binding solution, DNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA was eluted by Elution Buffer.

Storage and Stability
Proteinase K, RNase A, MagPure Particles should be stored at 2-8°C upon arrival. However, short-term storage (up to 24 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions.
