Norgen’s 2X PCR Master Mix is a ready-to-use solution that contains components required for PCR amplification including Taq DNA polymerase, dNTPs, reaction buffer, MgCl2, KCl and a PCR enhancer/stabilizer. The user needs only to add template, the primer set and water to the master mix in order to set up the PCR reaction. This convenient 2X PCR Master Mix reduces the time required to set up PCR reactions and reduces the possibility of contamination, particularly when preparing large numbers of reactions. The optimized master mix allows for robust amplification of DNA templates with high yields of PCR products.
Taq DNA Polymerase is a highly thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity and a very low 5´→ 3´ exonuclease activity. The source of Taq included with Norgen’s 2X PCR Master Mix is an E. coli strain with a cloned Taq DNA Polymerase gene from Thermus aquaticus YT-1.

Storage Conditions and Product Stability
Norgen’s 2X Master Mix should be stored at -20ºC. For everyday use an aliquot can be stored at 4ºC for up to three months. The Master Mix is stable for multiple freeze-thaw cycles (see Figure 2). When stored at the proper temperature this reagent is stable for at least 1 year.
For monitoring and detection of surface of equipment and personnel hygiene which have disinfectant or antibiotics.
Advantage:
1.This series of products was filling at A level of environment, and final sterilization by Gamma ray irradiation, triple packaging insure sterility and long shelf life.
2.Each dish was marking label product name, batch number, expiration date .Information is available of traceability.
3.Inner additional desiccant, reducing formation of condensation water, while inner additional sterile paper and plastic bags for easier transfer and cultivation.
4.Triple packing dense bags to avoid the penetration of hydrogen peroxide; clean gas was filled as a buffer to reduce broken bags and dish in transit..
5.This series of products is available to store at (2-25 ℃), shelf life of up to 6 months.
Storage: Store in a cool (2-25 ℃), dry place, away from bright light. Storage period of 6 months.

For selective isolation and culture of Staphylococcus aureus.
Peptone and beef extract powder provides carbon, nitrogen, vitamins and minerals; D- mannitol to fermentable sugars; higher levels of sodium chloride to provide a higher osmotic pressure, suppress most non-staphylococcal microorganisms ; phenolsulfonphthalein as pH indicator; agar is medium coagulant. Typical pathogenic staphylococci (coagulase positive) D- mannitol produce acid fermentation and produce yellow colonies with a yellow halo, typically non-pathogenic Staphylococcus unfermented D- mannitol to form red colonies.
