Bullseye EasyScript™ Reverse Transcriptase

Application

• Synthesis cDNA froma single-stranded RNA or DNA primer extension
• Sequencing dsDNA
• cDNA library
• Template production for use in PCR
• 3'-end labeling of duplex DNA via end-filling reactions

EasyScript™ Reverse Transcriptase is a genetically modified form of Moloney Murine Leukemia Virus Reverse Transcriptase (M-MLV). Both the EasyScript™ and EasyScript™ Plus are RNase H deficient (negative). The enzyme is purified from bacteria h o s t as a single holoenzyme of 71 kDa with the capacity of first-strand cDNA synthesis of template up to 9kb and can be used for routine cDNA synthesis.

Kit Components

Storage Buffer
 
50 mM Tris-HCl (pH 8.3), 100 mM NaCl, 0.1 mM EDTA, 5 mM DTT, 0.1% (v/v) Triton X-100, and 50% (v/v) glycerol.

Storage
 
Store at -20°C in a frost-free freezer. Multiple freezing and thawing of RNA should be avoided. Keep RNA on ice all the time. It is recommended that the first strand cDNA synthesis is carried out under conditions where RNase contamination has been eliminated.

General Protocol

RT-PCR reactions should be assembled in a RNA-free environment. The use of "clean", automatic pipettes designated for PCR and aerosol resistant barrier tips are recommended.

1. Thaw template RNA and all reagents on ice. Mix each solution by vortexing, and centrifuge briefly to collect residual liquid from the sides of the tubes. 
2. Prepare the following reaction mixture in a PCR tube on ice:

3. Incubate at 25°C for 10 minutes if random primer is used. Omit this step if Oligo(dT) primer or sequence specific primer are used.
4. Incubate the mixture at 42°C for 60 minutes.
5. Stop the reaction by heating at 85°C for 5 minutes. 
6. Chill on ice. The newly synthesized first-strand cDNA now can be used directly for PCR amplification.

Notes:
1. Isolation of poly(A)+ RNA from total RNA is not mandatory; however, doing so may improve the yield and purity of the final product. 
2. RNA sample must be free of contaminating genomic DNA.
3. Unlike the oligo(dT) priming, which usually requires no optimization, the ratio of a randomprimer to RNA is critical in terms of the average length of cDNA synthesized in the reaction. Increasing the ratio of random primer/RNA will result in higher yield of shorter (~500 bp) cDNA, whereas decreasing this ratio will produce longer products.

4. The synthesized cDNA should be stored at -20°C.

Bullseye DNA Safe Stain Plus

• Higher sensitivity
• Use in the same way as EtBr in agarose gel electrophoresis
• Detection of DNA and RNA
• Safest DNA stain by far
• Low cost
• 10,000X
• Excitation wavelengths at 290nm and 490nm

DNA SafeStain Plus is a highly sensitive green fluorescent DNA/RNA staining reagent for detecting nucleic acids in agarose and polyacrylamide gels. This unique stain gives high sensitivity for detection of double-stranded or single-stranded DNA and RNA. Gels can be post-stained or the stain can be added to gels during gel casting or to the gel running buffer. DNA SafeStain Plus has two excitation wavelength peaks at about 290nm and 490nm, and an emission wavelength at 530nm, making it compatible with a standard UV light box, a blue-light transilluminator, or a gel reader equipped with visible light excitation; such as, a 488 nm laser-based gel scanner.

DNA SafeStain Plus is in a 10,000X concentrated format that can be easily diluted 10,000 times for use in precast gel staining, or 5,000 times for use in post gel staining.

EZ Pack™ Agarose Tablets

• Eliminates weighing
• Fast dissolving, just two minutes
• Environmentally friendly, free from organic solvents
• Consistent, reproducible gels
• Enhanced resolution and clarity 

Researchers trust Benchmark’s Agarose LE to meet their electrophoretic needs for various applications. Now, the same agarose is available in a convenient, no-mess tablet.

Agarose LE is refined in an advanced process that excludes the use of organic solvents. The result is a cleaner end product with significantly reduced environmental impact. The agarose can be used for analyses of nucleic acids from 150 bp to 25,000 bp, protein electrophoresis, and various blotting protocols.

The low EEO of the agarose promotes increased electrophoretic mobility, yielding improved resolution and shorter run times. This also allows macromolecules and larger particles (subcellular fragments, viruses, etc.) to migrate more freely through the gel matrix. The consistently low EEO reduces band distortion (caused by counterflow) that can result from the presence of excessive sulfate-rich negative ions. The quick-dissolving EZ Pack™ tablet contains 0.5 g (500 mg) of Agarose LE, eliminating the hands-on time and inaccuracies normally associated with weighing. Use of the tablet is not only convenient and cleaner, but it also provides better consistency and reproducibility gel to gel.

Gel preparation is simple – add the desired number of tablets to the electrophoresis buffer, allow it to sit for two minutes, and then heat and pour as usual. The resulting gels are highly transparent, have exceptional thermal stability (ensuring safe and easy handling), and exhibit exceptionally low absorption of chemical staining agents.

EZ Pack™ Agarose Tablets are supplied in convenient blister packs for safe, clean dispensing.
