6-Formyl-2-pyridine-PEG4-DBCO is a bifunctional PEG linker featuring an aldehyde and a DBCO function. DBCO is a strained cyclooctyne which reacts with azide groups on target molecules while the aldehyde group is a versatile electrophile that is reactive towards amines, hydroxylamines, and hydrazines.

Overview
Convenient ready-to-use solution
High sensitivity and yield
Robust amplification
Norgen’s 2X PCR Master Mix is a ready-to-use solution that contains components required for PCR amplification including Taq DNA polymerase, dNTPs, reaction buffer, MgCl2, KCl and a PCR enhancer/stabilizer. The user needs only to add template, the primer set and water to the master mix in order to set up the PCR reaction. This convenient 2X PCR Master Mix reduces the time required to set up PCR reactions and reduces the possibility of contamination, particularly when preparing large numbers of reactions. The optimized master mix allows for robust amplification of DNA templates with high yields of PCR products.
Taq DNA Polymerase is a highly thermostable DNA polymerase that possesses a 5´→ 3´ polymerase activity and a very low 5´→ 3´ exonuclease activity. The source of Taq included with Norgen’s 2X PCR Master Mix is an E. coli strain with a cloned Taq DNA Polymerase gene from Thermus aquaticus YT-1.
2X PCR Master Mix (1 Vial, 100 Reactions) – Sufficient reagent for 100 x 20 µL reactions
Storage Conditions and Product Stability Norgen’s 2X Master Mix should be stored at -20ºC. For everyday use an aliquot can be stored at 4ºC for up to three months. The Master Mix is stable for multiple freeze-thaw cycles (see Figure 2). When stored at the proper temperature this reagent is stable for at least 1 year.

Product Info
Overview
Extract high quality & quantity total RNA including miRNA
No phenol step required; isolate all RNA in one fraction
Bind & elute all RNA irrespective of size or GC content, without bias
Very sensitive & linear down to a few cells without the need for carrier RNA
Isolate from a wide variety of specimens
Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Available in a variety of formats to suit your needs
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
Norgen’s Exosomal RNA Isolation Kit (for the extraction of RNA from EV’s that have been isolated using IZON’s qEV columns) constitutes an all-in-one system for the isolation of exosomal RNA from exosomes previously isolated using IZON’s qEV columns or concentrated using IZON’s EV Concentration kit. This kit allows for the isolation of RNA from intact extracellular vesicles (EVs) where the purification is based on spin column chromatography that employs Norgen’s proprietary resin.
The kit is designed to isolate all sizes of extracellular vesicle RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PR, reverse transcription PCR, Nothern blotting, RNase protection and primer extension, and expression array assays.

Storage Conditions and Product Stability All buffers should be kept tightly sealed and stored at room temperature (15–25°C). 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.
Ki-67 is a nuclear, non-histone protein that is expressed only during active phases of the cell cycle (G1, S, G2 and M), but not in the resting phases (G0 and G1 early phase). Although the antigen has also been associated with ribosomal RNA transcription, it is strongly linked to cell proliferation and has thus been indicated as an effective marker in grading the proliferation rate of tumors, including those of the brain, breast, cervix, and prostate.
