Propargyl-PEG4-NHS ester

Description 

The DM3100 ExcelBand™ 1 KB (0.25-10 kb) DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA ladder DM3100 is composed of 13 individual DNA fragments: 10k, 8k, 6k, 5k, 4k, 3k, 2.5k, 2k, 1.5k, 1k, 750, 500, and 250 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (3 kb and 1 kb) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Bromophenol blue which mimic the migration of 4,000 bp and 500 bp dsDNA during electrophoresis are also added for real time monitoring.

Overview

• Purification and enrichment of intact plasma/serum exosomes for functional studies
• Isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias
• Versatile plasma/serum input volume
• No phenol extractions, Proteinase K treatment, nor carrier RNA required
• No time-consuming ultracentrifugation, filtration nor special syringes required
• No precipitation reagents, nor overnight incubation required
• Compatible with plasma/serum from most species
• Pure exosomes are purified and are free from any other RNA-binding proteins
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin
• The purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services

Norgen’s Plasma/Serum Exosome and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the sequential isolation of exosomal RNA from different plasma/serum sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. These kits are designed to isolate all sizes of RNA, including microRNA, irrespective of size or GC content, without bias. These kits provide a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.

Storage Conditions and Product Stability
All solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. It is recommended to warm Lysis Buffer A for 20 minutes at 60°C if any salt precipitation is observed.

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.
