Sulfo DBCO-PEG4-Amine is a water-soluble carboxyl-reactive building block with extended PEG spacer arm. In the presence of of activators (e.g. EDC, or HATU), this reagent can be used to derivatize carboxyl groups or activated esters (e.g. The NHS ester) through a stable amide bond. The hydrophilic sulfonated spacer arm greatly improves water solubility of DBCO derivatized molecules and a provides a long and flexible connection. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

OverView
AZtaq™ DNA Polymerase is a high-quality DNA polymerase, originating form Thermus aquaticus. Being highly thermostable, AZtaq is ideal for use in polymerase chain reaction (PCR) applications.
The enzyme catalyses the synthesis of a complementary DNA strand using a primed DNA or cDNA strand as template. It possesses 5’-3’ exonuclease activity while lacking 3’-5’ proofreading activity.
AZtaq is compatible with the use of dUTP, enabling highly efficient removal of carry-over contamination with Cod UNG.

Product Info
Overview
Ensure optimal results for sensitive applications like NGS
Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
The purified exosomal RNA is free from any circulating RNA-binding proteins.
No phenol extractions, Proteinase K treatment, nor carrier RNA.
No time-consuming ultracentrifugation, filtration nor special syringes are required.
Concentrate isolated RNA into a flexible elution volume ranging from 50 μL to 100 μL.
Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary separation matrix.
Norgen’s EXTRAClean Plasma/Serum Exosome and Free-Circulating RNA Isolation Kit constitutes an all-in-one system for the purification of exosomes and the sequential isolation of RNA and free-circulating RNA from different plasma/serum sample volumes ranging from 50 μL and up to 10 mL. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that they do not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or any protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The RNA isolated from the purified exosomes is free from any protein-bound circulating RNA and is of the highest integrity. Moreover, the free-circulating, protein-bound, RNA is free from any exosomal RNA. The purified RNA can be used in a number of downstream applications including real time PCR, NGS application, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
All sizes, including miRNA and small RNA (< 200 nt)

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.
Brevetoxins (PbTx) are a class of cyclic polyether compounds produced by certain algae such as Karenia brevis. K. brevis can produce Brevetoxins in large quantities during an algae bloom which then pose a major health threat and are important to monitor and mitigate. Brevetoxins are the causative agent of Neurotoxic Shellfish Poisoning (NSP).
