Eight discrete bands, ranging from 100 to 1,000 bases
Higher intensity band at 500 bases for easy reference
No need for staining or destaining as loading dye contains ethidium bromide
Convenient lyophilized format provides better product stability
The Norgen 100 b RNA Ladder is a set of RNA transcripts derived from recombinant DNA templates. This ladder is suitable for precise sizing of small RNA molecules using native or denaturing agarose gels, and can be easily visualized under UV.
To reconstitute the lyophilized RNA ladder, add 250 µL of 1x loading buffer to each 25 loads vial and vortex gently. Heat at 80°C for 10 minutes. Incubate on ice for 1 min. Load 10 µL on a 1.5-2% gel. For optimal results, use Norgen 2x loading buffer with each RNA sample. There is no need for staining and destaining denaturing gels since Norgen’s loading buffer contains ethidium bromide.
Storage:
Store at -20°C.

Product Info
DBCO-Acid is a non-activated building block and adds minimal spacer to modified molecules. In the presence of activators such as EDC or HATU, this reagent can be used to derivatize amine-containing molecules through a stable amide bond. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.
MagPure Circulating DNA Rich Kit designed for purification of high quality circulating DNA (cfDNA) from cell-free body fluids (such as plasma, serum). The purified DNA is suitable for direct use in downstream applications such as PCR, real-time PCR, biochip analysis and NGS.

Principle
This product is based on the purification method of high binding magnetic particles. The sample is lysedand digested under the action of lysate and Protease. DNA is released into the lysate. After adding magnetic particles and binding solution, Large DNA(>500bp) will be adsorbed on the surface of magBindparticles. After removal of large size, small size of DNA(<500bp) will be adsorbed on the surface ofMagPure Particle F and impurities such as proteins will be removed without adsorption. The adsorbedparticles were washed with washing solution to remove proteins and impurities, washed with ethanol toremove salts, and finally DNA
Advantages
Economy – less than 50% of the price of Qiagen and other imported products
Automatic – without labour

Storage and Stability
Proteinase K, MagBind Particles and MagPure Particles F 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 dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
