Magnetic Beads (PCR Purification)

Solid Phase Reversible Immobilization magnetic beads consist of paramagnetic particles coated with carboxyl groups that reversibly bind DNA. They are used for DNA purification because they are fast, simple and efficient. Our Magnetic Beads (PCR Purification) combines BioDynami’s proprietary chemistries with reversible DNA-binding properties of magnetic beads. The beads are developed for effective PCR fragment purification by removing primers and unwanted components such as salts, dNTPs, enzymes, and others.

Our Magnetic beads (PCR Purification) are optimized to selectively bind PCR fragments of 80 bp and larger and remove primers that are 30 nt and shorter. Purified PCR fragments are suitable for any downstream applications. The beads can be used for PCR cloning, PCR cleanup, or even PCR fragment concentration.

Features:

• Effective purification of PCR fragments >80 bp
• Removal of primers <30 nt
• Removal of unwanted components
• Flexibility: compatible with manual and automated processing

Applications:

• Purification of PCR fragments
• PCR cloning
• Sequencing
• Other applications requiring purified PCR fragments

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.

Description

FluoroVue™ Nucleic Acid Gel Stain (10,000X) is specially designed for in-gel use and is a safer replacement for conventional Ethidium bromide (EtBr), which poses a significant health and safety hazard to its users. It is a fluorescent stain which offers highly sensitive detection of double-stranded or single-stranded DNA and RNA in a convenient manner. FluoroVue™ Nucleic Acid Gel Stain offers high sensitivity that is several times greater than EtBr. 

FluoroVue™ Nucleic Acid Gel Stain is compatible with both conventional UV gel-illumination systems as well as harmless long wavelength blue light illumination systems, like B-BOX™. When bound to nucleic acids, FluoroVue™ Nucleic Acid Gel Stain has a fluorescent excitation maximum of 250 and 482 nm, and an emission maximum of 509 nm. Therefore, it can replace EtBr without the need of changing existing lab imaging systems.

Features:

• Excellent for in-gel staining
• Sensitivity: 0.14 ng (DNA) or 1 ng (total RNA)
• A safer alternative to EtBr
• Compatibility: suitable to blue or UV light
• Increased cloning efficiency (blue light)

Storage

Protected from light
4°C for 12 months
-20°C for 24 months
