Vitamin B12, also called cobalamin, is a water-soluble vitamin that is involved in the metabolism of every cell of the human body: it is a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism. It is particularly important in the normal functioning of the nervous system via its role in the synthesis of myelin, and in the maturation of developing red blood cells in the bone marrow.
This kit is a product based on indirect-competitive ELISA, which is fast, easy, accurate and sensitive compared with common instrumental analysis.

Description
The ExcelRT™ One-Step RT-PCR Kit is designed for the reverse transcription and PCR amplification of a specific target RNA from either total RNA or mRNA. The ExcelRT™ One-Step RT-PCR Kit provides the user an alternative to the lengthy two step processes (first strand generation and amplification) by using a single mixture, single tube, one step reaction. The ExcelRT™ One-Step RT-PCR Kit contains a 2X reaction premix consisting of an optimized buffer, dNTPs, Mg2+ and enzyme stabilizer, and a blend of recombinant reverse transcriptase and Taq DNA polymerase. The ExcelRT™ One-Step RT-PCR Kit allows the user to complete the RT-PCR process using a thermocycler in a single reaction setting. The ExcelRT™ One-Step RT-PCR Kit is capable of detecting even trace amounts of target RNA and ideal for target RNA amplification and analysis.

The HiPure Liquid RNA & miRNA Kit integrates phenol/guanidine-based sample lysis and silica membrane purification of total RNA. MagZol LS Reagent, included in the kits, is a monophasic solution of phenol and guanidine thiocyanate designed to facilitate lysis of liquid sample and inhibit RNase. The high lysis efficiency of the reagent and the subsequent removal of contaminants by organic phase extraction enable the use of up to 0.25ml liquid sample per mini spin column.

Main Functions
Isolation total RNA from 0.25ml body fluids using column and MagZol LS reagent
Applications
qPCR / RT-PCR, liquid or solid-phasechip analysis, hybridization and SNP detection
0.25ml liquid samples are homogenized in 0.75ml MagZol LS Reagent. After addition of chloroform, the homogenate is separated into aqueous and organic phases by centrifugation. The upper, aqueous phase is extracted, and ethanol is added to provide appropriate binding conditions. The sample is then applied to the spin column, where the total RNA (up to 100 µg) binds to the membrane and phenol and other contaminants are efficiently washed away. High-quality RNA is then eluted in 30–100µl of RNase-free water.
Advantages
High quality – high purity total RNA can be directly used in various sensitive downstream applications
Fast – isolation of several samples can be completed in 40 minutes by using column purification method
Safety – no phenol chloroform extraction required
Sensitive – direct lysis of blood, plasma and other samples without separation of leukocytes

Storage and Stability
MagZol LS Reagent 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 their 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.

Product Info
Overview
CE-IVDR marked in accordance with the European Commission Regulation (EU) No. 2017/746.
Ideal for use in in vitro workflows
No need to immediately process samples
Nucleic acid preservation at room temperature over 2 years for DNA and 7 days for RNA
Ship stool samples at room temperature safely
Compatible with most DNA/RNA isolation methods
Norgen’s Stool Nucleic Acid Collection and Preservation Devices Dx are designed for the collection and preservation of nucleic acids from fresh stool specimens. The Stool Nucleic Acid Collection and Preservation Devices Dx – 50 contains 50 individual Stool Nucleic Acid Collection and Preservation Devices Dx. Each Stool Nucleic Acid Collection and Preservation Device Dx consists of Norgen’s Stool Nucleic Acid Collection and Preservation Tube Dx containing Norgen’s Stool Preservative in a liquid format. The user simply collects stool into the tubes (fill up to the line indicated on the tube) and mixes gently until the stool is well submerged under the preservative. The Stool Nucleic Acid Collection and Preservation Tube Dx is subsequently sent to the laboratory for DNA and/or RNA isolation and analysis. The stool DNA in preserved samples is stable for more than 2 years at room temperature, and the stool RNA in preserved samples is stable for 7 days at room temperature. DNA can be isolated from the preserved stool samples using Norgen’s Stool DNA Isolation Kit Dx (Cat. Dx27600) and RNA can be isolated from the preserved stool samples using Norgen’s Stool Total RNA Purification Kit Dx (Cat. Dx49500). These tubes are ideal for collecting and preserving DNA and RNA samples for in vitro diagnostic use for medical purposes.
