Introduction

This product uses an improved salt precipitation purification method to provide a safe and economical solution for High Weight genomic DNA extraction from blood samples, tissue samples, cultured cells, oral swabs, bacteria, and other samples. The extraction does not require the use of toxic phenol chloroform or any expensive reagents, making it the most economical reagent kit for nucleic acid extraction at present. This kit has no limit on the amount of sample used and can flexibly adjust various amounts of samples. The obtained DNA can be directly used for experiments such as PCR, enzyme digestion, Southern hybridization, and the Third-generation sequencing.

Principles

SolPure DNA Kits is an improved salt precipitation purification method. (Blood samples are lysed in red blood cell lysis buffer to remove red blood cells, and white blood cells are collected by centrifugation.) After lysis, DNA is released into the lysis buffer. RNA is removed by RNASE A. High salt solution is added to precipitate proteins and impurities. Centrifuge to remove precipitate and obtain supernatant containing only DNA. Add isopropanol to precipitate and recover DNA. Wash with 70% ethanol to remove salt, and finally add Buffer TE to dissolve DNA.

Storage and Stability

RNase A and Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 4 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 least18 months under these 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.

Norovirus is known to cause acute gastroenteritis. It is a small (27-38 nm), round, nonenveloped RNA virus belonging to the Caliciviridae family and is responsible for over 80% of non-bacterial outbreaks of gastroenteritis in the world. It affects individuals of all ages, with a distinct seasonal link to winter. It has a genome of 7.6 kb that is positive sense and has a single stranded linear confirmation. It encodes a major structural protein (VP1) of about 58 to 60 kDa and a minor capsid protein (VP2). Transmission occurs predominantly through ingestion of contaminated water, food and airborne transmission, as well as contact with contaminated surfaces. The ease with which norovirus is transmitted and the low infectious dose required to establish an infection results in extensive outbreaks in numerous environments, such as hospitals, hotels and schools. There is no antiviral drug available to treat this infection and little is known about its pathogenicity. However, it has been observed that the virus can be taken up by enterocytes where translation of viral nonstructural proteins can occur; it damages and alters intestinal microvilli, leaving them blunt and broadened, thus inhibiting absorption; it causes crypt cell hyperplasia and also leads to apoptosis of enterocyctes. An incubation period of 24-48 hours is usual. Infection is characterized by the acute onset of nausea, vomiting, abdominal cramps, aching limbs, raised temperature and diarrhoea that generally last for about 48 hours. However, more severe and prolonged infection may be observed in children and the elderly. There are five recognized norovirus genogroups, of which three (GI, GII, and GIV) are known to affect humans and, since 2002, variants of the GII.4 genotype have been the most common cause of norovirus outbreaks. There have been 31 different genotypes identified within the genogroups, with a wide degree of genetic variability present even within each genotype.

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit. Details of the target and priming specificity are included in the individual handbooks above.
