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:
50mM 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.

ENDURO VE20 Vertical Gel Electrophoresis System

Enduro VE20 Vertical Electrophoresis System (20 x 20 cm), includes glass plates, 2 x 24 well combs, cooling coil and casting base

• Large format vertical gel system
• Electroblotting and gel electrophoresis in same universal gel tank
• Quick assembly system for ease of use
• Complete system allows casting of gels and running of gels at same time increasing efficiency

The ENDURO VE20 is Labnet's new large format vertical gel electrophoresis system. It distinguishes itself in its flexibility of applications and ease of gel casting and set-up requiring only 4 screws to secure 4 gels. The same gel tank can house a large format electroblotting assembly sold separately. This system is ideal for first- and second dimension SDS-PAGE, native, preparative, gradient and high-resolution nucleic acid electrophoresis.

Innovative screw-clamp technology consists of only four screws to secure up to four 20 x 20cm gels. This vertical screw clamp technology distributes pressure evenly along the height of gel rather than in the center to eliminate plate bowing and gel compression, while maintaining a leak-proof seal during casting.

NO TANK TOP ASSEMBLY
A built-in inner buffer chamber within the PAGE insert allows set up to be completed without inclusion of an upper buffer chamber.

CASTING ADVANTAGES

• Dual purpose PAGE insert eliminates time consuming transfer of glass plates between separate casting and gel running components.
• Glass plates with bonded spacers assure clean well formation, correct alignment for leak-free casting and eliminates manually aligning spacers.
• Casting stand design ensures leak-free casting even if glass plates are misaligned.

Bullseye 1Kb DNA Ladder, Logic contains 16 DNA bands ranging from 100bp to 10Kb, formulated so that each band contains an amount of DNA that correlates logically to its size, allowing the user to estimate both the size and the quantity of specific fragments at a glance. It is particularly useful for protocols such as probe labeling, DNA sequencing and optimizing insert/vector ratio in ligation reactions, where DNA concentration must be taken into consideration.

Size: 1200 uL
Storage: Store at -20°C.
Concentration: 920 ng/6 uL

Loading Buffer Composition:

• 10mM Tris-HCl
• 1mM EDTA (pH 8.0)
• 0.02% Bromophenol blue
• 0.02% Xylene cyanol
• 5% Glycerol

Usage: Add 6 uL of Bullseye 1Kb DNA Ladder, Logic directly to wells designated for markers, which will yield the amount as indicated in the picture. You may use more than 6 uL of ladder, depending on well size and level of dye used to visualize the bands. Calculate the amount for each band according to your loading volume.

This brand is being discontinued and will only be available while supplies last.
