Overview

• Quantified standard to be used as a positive control or PCR quantification standard
• Vigorously quantified using multiple methods

Neisseria gonorrhoeae is a Gram-negative coccus of the Neisseria genus. N. gonorrhoeae is usually seen in pairs infecting human cells. It has a circular DNA genome of approximately 1Mbp encoding over 2000 genes. N. gonorrhoeae is the etiological agent of the sexually transmitted infection (STI) gonorrhoea, which globally causes an estimated 60 million new cases of gonococcal disease annually. It is second only to Chlamydia trachomatis as the most reported notifiable sexually transmitted disease. Infections with N. gonorrhoeae are primarily restricted to the mucus membranes of the endocervix, urethra, rectum, and pharynx. In females, gonorrhoea is a major cause of pelvic inflammatory disease and may lead to tubal infertility, ectopic pregnancy, and chronic pelvic pain, whereas in males it primarily causes urethritis. Importantly, these infections may often be asymptomatic, thereby contributing to further transmission and maintenance of the disease within populations.

Norgen’s Neisseria gonorrhoeae Quantified Bacterial DNA Standard is prepared from pelleted bacteria grown on culture plates 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 Neisseria gonorrhoeae.

Introduction

The MagPure Plasmid purification system uses the paramagnetic bead technology for high-throughput preparation of high-copy or low-copy plasmid DNA from E. coli cells. This kit also can be used with fosmid and BAC vector-based constructs. The system uses alkaline lysis followed by a MagPure purification to differentially bind plasmid DNA to paramagnetic beads. While the DNA is bound to the beads, contaminants can be rinsed away using a simple washing procedure. Because MagPure uses magnetic separation technology, the protocol does not require vacuum filtration. This makes kit extremely amenable to automation. Plasmid DNA purified with this system is most commonly used in Sanger Sequencing and PCR amplification.

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 Lysozyme. 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

1. Suitable for extracting plasmids from 1-5ml or <3ml YT medium.
2. The same amount of buffer 1, 2, and 3 avoids errors caused by adjusting the pipette, making it convenient to use in conjunction with automated workstations.
3. Containing buffer 1 for washing, reducing the problem of false high production.
4. The purified plasmid can be directly used for sequencing, enzyme digestion, PCR, and other applications.

MagPure Particle NB*	2.2 ml	11 ml	2 x 60 ml

Storage and Stability

RNase A and MagPure Particle NB 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 its performance. The remaining kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. After addition of RNase A, Buffer P1 is stable for 6 months when stored at 2-8°C.
