Cell Culture Plate 96 Wells

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 250 µL to 30 mL
  • Urine Exosome Purification Mini Kit (250 µL – 1 mL urine)
  • Urine Exosome Purification Midi Kit (2 mL – 10 mL urine)
  • Urine Exosome Purification Maxi Kit (11 mL – 30 mL urine)
• 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 protein-bound cell-free circulating RNA
• 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 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.

Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples.

Description

Organophosphate compounds (OP) account for the largest class of rural and urban poisons in the world that are used to kill pests but can also be toxic to humans.  OPs cause toxicity by means of blocking the acetylcholinesterase enzyme (AchE).  The AChE-directed OPs react with a serine residue that is located at the catalytic site found within the AChE gorge. The OP targeted enzyme is no longer able to hydrolyze ACh, resulting in the buildup of ACh in the nerve synapse. This effect causes excessive excitation of the nerves, producing uncoordinated movements, tremors, paralysis and death.  Both synthetic and natural(Guanitoxin) organophosphates are dangerous to humans — exposure can lead to visual, coordination, muscular, and neurological deficiencies, and in some cases even to death.  In turn, exposure to OP is a significant public health concern which would significantly benefit from an improved detection platform.

Attogene’s Organophosphate detection kit is in designed specifically to detect Organophosphate in liquid samples.  For solid samples a simple sample preparation method is performed.  The ability to detect Organophosphate is performed is simple and sensitive.  The reaction uses a chromophore that can be detected by eye. In the presence of Organophosphate, the rate of chromophore production is reduced in a concentration dependent fashion.  The higher the concentration of Organophosphate the less color is produced.

Isothermal nucleic acid Principle Summary

The kit is based on room and constant temperature nucleic acid rapid amplification technology, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension. The kit relies on the role of NFO enzyme and adds the designed specific molecular probes according to the template, and get the result by colloidal gold technology (sandwich method).
