DBCO-PEG4-Maleimide is PEG linker containing a maleimide group and a DBCO moiety. The hydrophilic PEG spacer arm improves solubility in aqueous buffers. Maleimide group specifically and efficiently reacts with thiols to form stable thioether bonds. The low mass weight will add minimal spacer to modified molecules and will enable simple and efficient incorporation of DBCO moiety onto cysteine-containing peptides or other thiol-containing biomolecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
The ExcelRT™ One-Step RT-PCR Kit is designed for the reverse transcription and PCR amplification of a specific target RNA from either total RNA or mRNA. The ExcelRT™ One-Step RT-PCR Kit provides the user an alternative to the lengthy two step processes (first strand generation and amplification) by using a single mixture, single tube, one step reaction. The ExcelRT™ One-Step RT-PCR Kit contains a 2X reaction premix consisting of an optimized buffer, dNTPs, Mg2+ and enzyme stabilizer, and a blend of recombinant reverse transcriptase and Taq DNA polymerase. The ExcelRT™ One-Step RT-PCR Kit allows the user to complete the RT-PCR process using a thermocycler in a single reaction setting. The ExcelRT™ One-Step RT-PCR Kit is capable of detecting even trace amounts of target RNA and ideal for target RNA amplification and analysis.

The RNA Seq Library Prep Kit was developed for construction of high quality NGS libraries for next generation sequencing (illumina and MGI Platforms). RNA Sequencing is a very powerful tool to analyze transcriptome such as gene expression and transcription regulation, splicing characterization, mutation and variation detection etc. The kit needs purified RNA (example: rRNA depleted RNA or polyA mRNA) as input for library construction. Library multiplexing is possible with different types of indexes.
RNA Seq Library Prep Kit Workflow
Three index types are available for the illumina platform kits:
Non-index (illumina Cat.# 30055): Libraries do not have index.
Index (illumina Cat.# 30056): A unique barcode sequence with 6 bases has been included in each of the index primers. RNA Sequencing library multiplexing is possible with up to 48 samples. Index information can be downloaded here.
Unique dual index (illumina Cat.# 30057): RNA Sequencing library multiplexing up to 96 samples is possible with the unique dual indexes. We have developed a 4-Base Difference Index System. The system can generate indexes with at least 4 bases different from others in the 8-base indexing region. the unique dual indexing primers identify sequencing errors such as index hopping, mis-assignment, and de-multiplexing errors. Index information can be downloaded here.
Indexes are available for the MGI platform kits (Cat.# 34112).

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.
