Introduction

This product is suitable for extracting total viral nucleic acid from cell-free/low-content cell biological samples such as body fluids, serums, plasma, soaking solutions, tissue homogenate supernatant, and culture supernatant. The Purified DNA/RNA is used for RT-PCR and PCR detection.

Principle

This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. DNA/RNA is released into the lysate. After adding magnetic particles and binding solution, DNA/RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were washed with washing solution to remove proteins and impurities, washed with ethanol to remove salts, and finally DNA/RNA was eluted by Nuclease Free Water.

Description

Attogene Fluorescent Universal Lateral Flow Assay Kits are a convenient ready-to-use kit for quick and cost-effective development of a fluorescent lateral flow dipstick assay for detection of DNA and RNA products.

Fluorescent lateral flow assays can be 2-100 fold more sensitive that gold based lateral flow tests.

Formats (fluorescent broad range UV light excitation range of 100nm to 400nm, 655nm emission) Streptavidin conjugate pad):

• • Detectable using a black light such as a black light UV flashlight or fluorescent lateral flow reader.
• • Detection of nucleic Acid (DNA or RNA) requires the use of a biotin and FAM-labelled primer during amplification. 
• • Test line: anti-FITC/FAM
• • Control Line: Biotin
• • Multiplex detection of nucleic Acid (DNA or RNA) requires the use of a biotin, FAM and Dig labelled primers during amplification.:
• • Test Line #1: anti FITC/FAM, Line #2: anti-Dig, Line #3 Biotin.

Inquire about custom configurations: [email protected]. 

For example, this product can be configured with alternative/custom streptavidin fluorescent particles.

Kit Components 

• 50 -4.5mm Fluorescent Lateral Flow Dipsticks
• 10 mL Sample assay running buffer

Features & Benefits

• Can be used for development of a lateral flow assay for detection of a variety of different molecules such as amplified DNA products from PCR, LAMP and RPA reactions.
• No need to stripe capture antibodies
• No expensive equipment required (Black Light)
• Cost-effective way to screen for further downstream lateral flow assay development.

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.
