DBCO-PEG12-NHS Ester is a monodisperse PEG linker which enable free copper click chemistry with N3 group. NHS ester moiety can react specifically and efficiently with primary amines to form a covalent amide bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.
Propargyl-PEG2-acid is a linker consisting of propargyl and carboxylic acid functional groups. In the presence of activators (e.g. EDC, or HATU), the carboxylic acid reacts with primary amine to form a stable amide bond. The propargyl group reacts with azide group in biomolecules to yield a stable triazole linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Norgen’s EXTRAClean Urine Cell-Free Circulating RNA Purification Kits provide a fast, reliable, reproducible, and simple procedure for isolating circulating RNA and exosomal RNA from various urine inputs ranging from 250 μL and up to 30 mL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real-time PCR, reverse transcription PCR, Northern blotting, RNase protection and primer extensions, and expression array assays.
EXTRAClean Cell-Free Circulating RNA Purification Mini Kit: For sample volumes ranging from 250 μL to 2 mL
EXTRAClean Cell-Free Circulating RNA Purification Midi Kit: For sample volumes ranging from 2mL to 10mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL
EXTRAClean Cell-Free Circulating RNA Purification Maxi Kit: For sample volumes ranging from 10 mL to 30 mL. The first column will handle the large volume input of urine that is followed by a concentration on a mini column for a final elution of 50 μL to 100 μL.
