Description

Attogene’s Nano-clay Powder is comprised of thin layers and each layer has a thickness of one to a few nanometers length from a few hundred to several thousand nanometers. Nanparticles are utilized as fillers or additives in polymers for variety of desirable effects are receiving an increased interest for research and development. Different types of nanoparticles, such as nanocarbon, carbon nanotubes, nano-clays, and metal oxides, are recently employed to modify the polymer performance.

The viable interest is in the utilization of nano-clays for the alteration of polymeric material for numerous applications. This may be indicated from the increased commercial interest, and utilization of clay nanocomposites. It is an organic and hydrophilic. Moreover, the nanoclays are added in the polymers to increase the mechanical properties of polymers. In the nanocomposites, the permeability of the gases such as oxygen, carbon dioxide can be reduced by the addition of nanoclays. Nano clays have wide range of applications in food-packaging, pharmacy, used as a drug vehicle, textile industry etc.

Promotes flocculation of cyanobacteria cell debris, binds residual phosphate compounds and promotes gradual settling of the cyanobacterial biomass on the sediment.

Sample Package Size: 500g

Introduction

The Kit is designed for purification of total RNA, including miRNA and other small RNA molecules (18nt), from cultured cells and various animal and human tissues, including difficult-to-lyse tissues samples.

Principle

Biological samples are first lysed and homogenized in a highly denaturing guanidine isothiocyanate-containing buffer, which immediately inactivates DNases and RNases to ensure isolation of intact DNA and RNA. The lysate is then passed through a Mini spin column. This column, in combination with the high-salt buffer, allows selective and efficient binding of genomic DNA. Flow-through from the column is digested by Proteinase K in the presence of ethanol. This optimized digestion, together with the subsequent addition of further ethanol, allows appropriate binding of total RNA, including miRNA, to the column. Contaminants are efficiently washed away and high-quality RNA is eluted.

Advantages

• High quality – one step RNA extraction reagent combined with silica gel column can obtain the highest concentration
• Fast – several samples can be extracted in 40 minutes
• High applicability – samples including animals, plants, bacteria, cells, etc.
• High concentration – efficiently remove macromolecular RNA, enrich small RNA and improve sensitivity
• Safe – no phenol chloroform extraction and no use of Trizol reagent

Storage and Stability

Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 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.

The Kit is designed for purification of total RNA, including miRNA and other small RNA molecules (18nt), from cultured cells and various animal and human tissues, including difficult-to-lyse tissues samples.

Overview

• Purification and enrichment of intact exosomes from plasma, serum, urine, cell culture media and saliva in less than 30 minutes.
• Versatile sample input ranging from 50 µL to 10 mL
  • Plasma/Serum Exosome Purification Mini Kit (50 µL – 1 mL Plasma/Serum)
  • Plasma/Serum Exosome Purification Midi Kit (1 mL – 4 mL Plasma/Serum)
  • Plasma/Serum Exosome Purification Maxi Kit (4 mL – 10 mL Plasma/Serum)
• Exosome purification is based on Norgen’s proprietary resin separating matrix through exosomes’ surface proteins.
• No precipitation reagents, overnight incubation, protease or coagulant treatments required
• No time-consuming ultracentrifugation, filtration or special syringes required
• Purify intact exosomes with a size ranging from 40-200 nm depending on sample input type
• Purified exosomes are compatible with functional studies.
• Purified exosomes are free from any RNA-binding proteins
• Purified exosomes are compatible with NanoSight® or Electron Microscopy for assessing the approximate exosome size range and concentration.
• Exosomal RNA can be extracted from the purified exosomes using Norgen’s Exosomal RNA Purification technology or any other RNA extraction method.

The Plasma/Serum Exosome Purification Kits provide a fast, reliable and convenient method to purify and enrich for intact exosomes from different plasma/serum sample volumes ranging from 50 µL to 10 mL. These kits also allow for the purification of intact extracellular vesicles (EVs) from different plasma/serum 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 transcripts.

NanoSight® Analysis

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

Exosomal RNA Analysis

To purify exosomes and isolate exosomal RNA, choose the Plasma/serum Exosome Purification and RNA isolation kits. The protocol is divided into 2 parts and an aliquot of purified exosomes can be taken for applications like NTA/TEM etc. before processing them for RNA isolation. Or you can use the Exosomal RNA Isolation Kit if you’ve already purified exosomes using a Norgen kit or another method. . Exosomal RNA isolation is based on Norgen’s proprietary resin without the need for phenol extractions or carrier RNA. This RNA is ideal 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. This kit is stable for 2 years after the date of shipment.

Important Note
This kit is suitable for the purification of exosomes from fresh or frozen serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
