The Formic Acid test kit is a simple method for the rapid, reliable measurement and analysis of formic acid (formate) in foods, beverages and other materials.

Introduction

The Kit provides fast purification of high-quality RNA from plants, cell, tissues, and yeast using silica-membrane spin columns with a binding capacity of 100μg RNA. There is no need for phenol/chloroform extractions and time-consuming steps such as CsCl gradient ultracentrifugation or precipitation with isopropanol or LiCl. RNA purified using the RaPure Total RNA Purification System can be used for applications such as RT-PCR, Northern blotting, poly A+ RNA (mRNA) purification, nuclease protection, and in vitro translation.

Principle

The Kit isolates total RNA from up to 150mg plant tissue. A short workflow enables RNA isolation with genomic DNA removal in less than 25 min. Samples are first lysed and homogenized. The lysate is passed through a DNA Mini column, ethanolis added to the flow-through, and the sample is applied to an RNA column. RNA binds to the membrane and contaminants are washed away. High-quality RNA is eluted in as little as 30µl water using the Kit.

Advantages

• Efficient removal of DNA – unique genomic DNA removal column without DNase treatment
• High quality – high purity total RNA can be directly used in various sensitive downstream applications
• Fast – several samples can be extracted in 25 minutes by column method
• Safe – no phenol chloroform extraction required
• Sensitive – RNA can be recovered at the level of PG
• Broad spectrum – various types of plant samples can be processed by diversity of operating procedures

Storage and Stability

The Kit can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. Make sure that all buffers are at room temperature when used. During shipment, crystals or precipitation may form inthe Buffer RLC/PRC1. Dissolve by warming buffer to 37°C.

Purchase Guide

1. When dealing with woody or uncommon samples, R4150 is recommended first. R4150 contains two polysaccharide/polyphenol lysis buffer, which is the most universal product.

2. R4151 is recommended for handling common economic crop samples for the first time. Strong lysis solution can be used to process easy-extraction samples. The amount of corn or rice leaves samples can reach up to 300mg.

3. R4165 adopts CTAB/chloroform method, which can also handle a large number of difficult-to-extraction plants, but requires contact with chloroform substitutes, which is less safe than other kits. This kit uses DNase Ⅰ to remove DNA, which is also a good choice for extracting polysaccharide/polyphenol-rich plant samples.

4. R4014 is recommended for fruit/starch plant samples, which uses improved trizol pre-treatment, single column operation and is more economical.

Overview

• Ensure optimal results for sensitive applications like NGS
• Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
• Purification and enrichment of intact urinary exosomes for functional studies.
• Bind and elute all RNA irrespective of size or GC content, without bias.
• Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias.
• No phenol extractions, Proteinase K treatment, nor carrier RNA required.
• No time-consuming ultracentrifugation, filtration nor special syringes are required.
• No precipitation reagents nor overnight incubation required.
• Compatible with urine from any species.
• Pure exosomes are purified and are free-from any other RNA-binding proteins.
• Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary resin separation matrix.

Norgen’s EXTRAClean Urine Exosome Purification and RNA Isolation Mini Kit constitutes an all-in-one system for the purification of exosomes and the subsequent isolation of RNA from different urine sample volumes ranging from 250 μL to 1 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The purified RNA is free from any protein-bound circulating RNA and of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, NGS application, Northern blotting, RNase protection and primer extension, and expression array assays.
