N-(Aminooxy-PEG2)-N-bis(PEG3-propargyl) consists of two terminal propargyl groups and an aminooxy group. The propargyl groups reacts with azide-bearing compounds or biomolecules via copper catalyzed Click Chemistry. The aminooxy group is reactive towards aldehydes to form oxime bonds. If a reductant is used, it will form a hydroxylamine linkage. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Description
The DM2100 ExcelBand™ 100 bp DNA Ladder is a ready-to-use DNA ladder, which is pre-mixed with loading dye for direct gel loading. The DNA ladder DM2100 is composed of 11 individual DNA fragments: 1.5k, 1k, 900, 800, 700, 600, 500, 400, 300, 200 and 100 bp derived from a mixture of PCR products and specifically digested plasmid DNA. This product contains two enhanced bands (1.5 kb and 500 bp) for easier reference. In addition, two tracking dyes, Xylene cyanol FF and Orange G which mimic the migration of 4,000 bp and 50 bp dsDNA during electrophoresis are also added for real time monitoring.

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.

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.
