DBCO-PEG12-DBCO is a monodisperse click chemistry linker containing two terminal DBCO groups with hydrophilic PEG spacer arm. DBCO will react with azide-bearing compounds or biomolecules to form a stable triazole linkage without copper catalyst. PEG spacer arm can increase water solubility and membrane permability. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Description
Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.
Key Features
Storage and stability
Store Q-PAGE™ Precast Gels at 4°C for periods up to 12 months.
Do not freeze Q-PAGE™ Precast Gels Remove tape and comb before electrophoresis.
Keep Q-PAGE™ Precast Gels flat during storage.

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)

Storage Conditions and Product Stability
2X One-Step RT-PCR Master Mix should be stored at -20°C. For everyday use an aliquot can be stored at 4°C for up to 3 months. Repeated freeze-thaw cycles are not recommended. When stored at the proper temperature this reagent is stable for at least 1 year.
These kits provide a convenient and rapid method for the isolation of microorganisms from water samples. The kits allows for the rapid isolation and purification of total RNA and DNA simultaneously from the microorganisms found in different types of water samples. The total RNA and DNA (including genomic DNA) are isolated from all the microorganisms found in the water, including bacteria, fungi and algae without the use of any inhibitory organic substances The kit purifies genomic DNA, and all sizes of RNA, from large mRNA and ribosomal RNA down to microRNA (miRNA) and small interfering RNA (siRNA). The purified RNA and DNA are highly concentrated, and can be used directly in a number of downstream applications including PCR, qPCR, RT-PCR, qRT-PCR, Northern blotting, Southern blotting and sequencing reactions.
Water RNA/DNA Purification Kit (Spin Column + Filters Kits)
These kits are available with 0.45 μm or 0.22 μm filter formats for capturing microorganisms present in the water.
Water RNA/DNA Purification Kit (Spin Column)
This kit is sold without filters columns.
