N-(Boc-PEG4)-N-bis(PEG4-propargyl) is a trifunctional chemical containing two terminal alkynes and a Boc-protected primary amine. The terminal alkynes are used in copper click chemistry with azides to form stable triazole linkages with the target molecule while the carboxylic acids are reactive towards alcohols and primary amines to form esters and amides respectively.

The L-Asparagine/L-Glutamine/Ammonia test kit is a novel method for the specific, convenient, cost effective and rapid measurement and analysis of L-asparagine, L-glutamine and ammonia as acrylamide precursors in the food industry, or as cell culture media/supernatant components, or in other materials.
Norgen’s PCR and Sequencing Reaction Clean-Up Kit (Magnetic Bead System) provides a rapid, simple and efficient procedure for the purification and clean-up of sequencing and various other enzymatic reactions including restriction enzyme digests, Klenow reactions, alkaline phosphatase reactions, and ligations. The kit is used to remove reaction contaminants including dye terminators, salts, enzymes, excess primers and primer dimers. Contaminants are undesirable as they can interfere with many downstream applications including sequencing, RFLP, restriction enzyme digestions and ligation. Purification is based on magnetic beads without the use of phenol, chloroform or alcohol precipitation. The kit provides a high quality product with up to 90% recovery.
Norgen’s PCR and Sequencing Reaction Clean-Up Kit (Magnetic Bead System) is also available in a 96-well format for high throughput applications. Purification with the 96-well plates can be integrated with a robotic automation system.

Norgen’s 2X One-Step RT-PCR Master Mix is a ready-to-use solution that contains components required for RT-PCR amplification of RNA templates. The mix includes M-MuLV reverse transcriptase, Taq DNA polymerase, dNTPs, reaction buffer, MgCl2, KCl, and a PCR enhancer/stabilizer. The user needs only to add the template, the primer set and water to the Master Mix to set up the RT-PCR reaction. This convenient 2X One-Step RT-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 RNA 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 One-Step RT-PCR Master Mix is an E. coli strain with a cloned Taq DNA Polymerase gene from Thermus aquaticus YT-1. M-MuLV Reverse Transcriptase is an RNA-directed DNA polymerase that can synthesize a complementary DNA strand initiating from a primer using either RNA (cDNA synthesis) or single-stranded DNA as a template. The source of the Reverse Transcriptase included with Norgen’s 2X One-Step RT-PCR Master Mix is an E. coli strain with a cloned reverse transcriptase gene from M-MuLV.
Norgen’s 2X One-Step RT-PCR Master Mix is available in 3 convenient sizes:
Cat # 28113 – 100 reactions (sufficient for 100 reactions x 20 µL reaction volume)
Cat # 28114 – 200 reactions (sufficient for 200 reactions x 20 µL reaction volume)
Cat # 28115 – 500 reactions (sufficient for 500 reactions x 20 µL reaction volume)
