Introduction

This product is specially designed for stool RNA extraction. The kit is suitable for extracting high-purity microbial or host cell RNA from ≤ 0.15g stool samples. The purified RNA can be directly used in RT-PCR and Northern hybridization.

Details

Principle

The Kit combines the speed and efficiency of silica-based technology with the convenient handling of magnetic particles for purification of total RNA. Samples are lysed and RNA is purified from lysates in one step through its binding to the silica surface of the particles in the presence of a chaotropic salt. The particles are separated from the lysates using a magnet and DNA is removed by treatment with RNase-free DNase. The magnetic particles are efficiently washed, and RNA is eluted in RNase-free water.

Storage and Stability

MagPure RNA Particles should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, MagPure RNA Particles up to 8 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.

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.

Cluster of differentiation 44 (CD44) is a glycoprotein receptor for hyaluronic acid, which plays a fundamental role in cellular adhesion, stromal binding, migration, and cell-cell interactions. Studies have suggested that the CD44-hyaluronate interaction is central to tumor invasiveness. Positive staining with Anti-CD44 is implicated in a multitude of different cancer types, including breast, prostatic, renal cell, colonic, hepatocellular, and genitourinary carcinomas, as well as Non-Hodgkin’s Lymphoma, metastatic melanoma, gastric cancer, and some soft tissue tumors. It has also been demonstrated that there is a positive correlation between tumor progression and increased expression of CD44v, a high molecular weight CD44 isoform that has been described in epithelial cells. Given the expression of CD44 in a wide range of cancers, the most practical application of CD44 immunostaining is its use in discriminating between urothelial transitional cell carcinoma in situ from non-neoplastic changes in the urothelium.
