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.

Plasmid MiniPrep Kit & High Throughput Kit (Magnetic Beads)

The kits were developed for plasmid miniprep directly from bacterial cultures. 100% centrifuge-free; NO vacuum needed; No column needed.

Plasmid MiniPrep Kit (Magnetic Beads), Cat.# 50012
– Use 2 ml of bacteria culture directly

Plasmid MiniPrep High Throughput Kit (Magnetic Beads), Cat.# 50011
– High throughput: Use 0.2 ml of bacteria culture directly with 96-well plates
– Low throughput: Use 0.2 ml of bacteria culture directly with 1.5 ml tubes

---

The kits can be used for both high copy and low copy numbers of plasmid DNA. With BioDynami’s proprietary magnetic beads technology, the kits eliminate the requirement of centrifuge, vacuum, and column. Our magnetic beads provide a robust and reliable tool for both high throughput and low throughput applications of plasmid DNA isolation with high binding capacity and fast magnetic response time.

The High Through kit (Cat.# 50011) can be used for both high throughput and low throughput extraction of plasmid DNA. Up to 96 samples can be extracted simultaneously when using a 96-well plate.

Yield of plasmid DNA may vary dependent on the bacteria strain, plasmid type, copy numbers, and growth conditions etc. DNA extracted using the kit is suitable for downstream applications such as qPCR, PCR, DNA sequencing, molecular cloning, restriction enzymatic digestion, transfection, and transformation etc. The isolated plasmid DNA with the magnetic beads is free of contaminations such as RNA, bacterial DNA, proteins, and other impurities.

Plasmid DNA were loaded on 1% of agarose gel after extraction.

• Purified exosomes are compatible with functional studies.
• Purified exosomes are free from any protein-bound cell-free circulating RNA
• Purified exosomes are compatible with NanoSight® or Electron Microscopy for assessing the approximate exosome size range and concentration.

The Urine Exosome Purification Kits provide a fast, reliable and convenient method to purify and enrich for pure intact exosomes from different urine sample volumes ranging from 250 µL to 30 mL. These kits also allow for the purification of intact extracellular vesicles (EVs) from different urine sample volumes, and these EVs are ready for any downstream application. The purification is based on Norgen’s proprietary resin.

These kits provide a clear advantage over other available methods since they do not require any special instrumentation, ultracentrifugation, precipitation reagents or any protease treatments. More importantly, the purified exosomes will not be contaminated with any other RNA-binding proteins that may contaminate your exosomal RNA, which is essential if studying exosomal RNA gene expression.

NanoSight® Analysis

Exosomes enriched with Norgen’s Urine Exosome Purification Kits can be analyzed using NanoSight® for assessing the approximate exosome size range and concentration.

Exosomal RNA Analysis

Exosomal RNA can be isolated using Norgen’s Exosomal RNA Isolation Kit from exosomes enriched using Norgen’s Urine Exosome Purification Kits for gene expression analysis using RT-qPCR, microarray or NGS and for Biomarker discovery.

Storage Conditions and Product Stability
All buffers should be kept tightly sealed and stored at room temperature. These kits are stable for 2 years after the date of shipment.

Important Note
Urine samples stored at -70°C, -20°C or at 4°C will develop some precipitation due to the aggregation of some of the highly abundant proteins in urine. Eliminating these precipitates using centrifugation or filtration may cause the loss of exosomes. Furthermore, these precipitates may affect the quality of the purified nucleic acid. We recommend the use of Norgen’s Urine Preservative when collecting urine samples, which is designed for the preservation of nucleic acids and proteins in fresh urine samples at ambient temperatures. The components of the Urine Preservative allow samples to be stored for over 2 years at room temperature with no detected degradation of urine DNA, RNA or proteins. Norgen’s Urine Preservative is available as a liquid format in Norgen’s Urine Preservative Single Dose Ampules, as well as in a dried format in Norgen’s Urine Collection and Preservation Tubes.
