Kit contents
Champion™ Competent Cells
pUC19 Control Plasmid (5 μl, 10-4 μg/μl)
Champion™ Transformation Protocol Card
Shipping condition
Throughout the shipping process, the temperature is maintained under -70°C.
Storage and expiration
Champion™ Competent Cells must be stored between -70°C to -80°C. Subsequent freeze-thaw cycles will reduce transformation efficiency. If high efficiency is required for the experiment, do not use aliquots that have gone through several freeze-thaw cycles. The efficiency of Champion™ Competent Cells lasts for 1 year with proper storage.

Overview
Quantified standard to be used as a positive control or PCR quantification standard
Vigorously quantified using multiple methods
Mastitis is the single most costly disease of dairy cattle resulting in the reduction of milk yield and quality. The inflammation of the utter is mainly caused by bacteria, and Staphylococcus aureus (S. aureus) is often considered the most common cause of contagious mastitis in dairy herds. S. aureus infection is estimated to be present in up to 90% of dairy farms and is responsible for 35% of the economic loss in the dairy industry. S. aureus is a facultatively anaerobic, Gram positive bacterium. The majority of S. aureus strains are catalase-positive and coagulase-positive, which forms the basis of traditional identification methodology.
Staphylococcus aureus Quantified Bacterial DNA Standard is prepared from cultured bacteria using Norgen’s sample preparation technology. The purified DNA is quantified vigorously using multiple methods including spectrophotometry, gel densitometry and real-time PCR. It is intended to be used as a positive control or PCR quantification standard for Staphylococcus aureus.
Upon receipt, store Norgen’s Staphylococcus aureus Quantified Bacterial DNA Standard at -20oC or lower. Avoid multiple freeze-thaw cycles. If needed, prepare smaller working aliquots and store at -20oC or lower.
This kit is designed to rich and extract 100bp-500bp circulating DNA from 5 ml cell-free body fluids (such asplasma, serum), and remove fragments above 500bp. Machine reaction only takes 90 minutes. Magnetic-particle technology provides high-quality DNA that is suitable for direct use in downstream applications such as PCR and next generation sequencing.

Principle
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.
Advantages
Economy – less than 50% of the price of Qiagen and other imported products
Automatic – without labour

Storage and Stability
MagPure Particles G, MagBind Particles and Proteinase K should bestored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored dry at roomtemperature (15–25°C) and are stable for at least 18 months underthese conditions.The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
