Bullseye DNA SafeStain,10,000x 

• Safest DNA stain by far
• Replaces EthBr in agarose gel electrophoresis
• Detection of DNA and RNA
• Excitation at 290 nm & 490 nm
• Emission at 530 nm

DNA SafeStain is a new and safe nucleic acid stain for visualization of double-stranded DNA, single-stranded DNA, and RNA in agarose gels. The dyes are developed to replace toxic ethidium bromide (EthBr, a potent mutagen), commonly used in gel electrophoresis for visualization of nucleic acids in agarose gels. DNA SafeStain is non-carcinogenic by the Ames-test. The results are negative in both the mouse marrow chromophilous erthrocyte micronucleus and mouse spermary spermatocyte chromosomal aberration tests.

DNA SafeStain emits green fluorescence when bound to DNA. It has two excitation wavelength peaks when bound to nucleic acid, at 290nm and 490nm and the emission can be detected at 530nm.

Storage:
Store under dark at 4°C or room temperature.

User Instruction: 
DNA SafeStain can be used in the exact same way as EtBr in agarose gel electrophoresis. For example, add 100µl to 1 liter of 1X running buffer (1xTAE or 1x TBE), and use this DNA SafeStain containing buffer to make the agarose gel and run the gel.

Special Notes: 
1. For best results, dilute the DNA SafeStain 1:10,000 in your gel running buffer and use this dye-containing running buffer to make your agarose gel and to run the gel.

2. As is the case with EtBr; add more DNA SafeStain, if brighter DNA bands are desired. To view the results, any conventional DNA gel viewing light box or gel documentation system should work well with the DNA SafeStain; although, using a LED light instead of a UV light source is preferred due to the harmful nature of UV light.

Bullseye RT 2X Master Mix

• Up to 9kb cDNA synthesis
• Ensures sample to sample consistency
• Large RNA sample volume capacity
• Ready to use

Size: 100 rxns

RT 2X Master Mix is a proprietary, ready-to-use master mix for first-strand cDNA synthesis in a 2X concentration. This optimized reaction mix contains ribonuclease inhibitor, dNTPs, and a balanced concentration for oligo(dT) and random primers. The ribonuclease inhibitor effectively protects RNA template from degradation. The oligo(dT) anneals selectively to the poly(A) tail of mRNAs and the random primers do not require the presence of poly(A) and they are utilized for the transcription of mRNA 5-end regions. The resultant cDNA can be directly used as template in different PCR experiments.

Kit Components

Storage

2. Assemble the following components in a tube on ice, and mix well:

1. Heat the mixture at 65°C for 5 mins and incubate on ice for at least 1 min.
2. Collect all components by a brief centrifugation and add 1 µl of the EasyScript RTase to the tube.
3. Mix well and collect all the components by a brief centrifugation.
4. Incubate the tube at room temperature for 10 min for annealing.
5. Perform cDNA synthesis by incubating the tube for 50 min at 42°C.
6. Stop the reaction by heating it at 85°C for 5 min.

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.

• Inert yellow dye helps reduce pipetting errors
• Room temperature stable for up to 30 days
• Compatible with fast cycling protocols
• Highly sensitive for low copy number templates
• Includes PR1MA Hot Start Taq Polymerase

Successful PCR requires careful control of many variables.  Pipetting errors, poor performing polymerases, dNTP concentrations, are just a few of the variables that can all contribute to reaction problems.  PR1MA has developed their new qMAX™ Gold to control these variables and help you achieve the best possible amplification performance. To reduce the chance of pipetting errors, qMAX™ Gold includes an inert yellow dye so small volumes are easy to visualize in PCR plates.  

qMAX™ Gold is a ready to use, 2X mastermix of PR1MA Hot Start Taq enzyme, dNTPs, a sensitive fluorescent intercalating dye, and optimized reaction buffer.  The Hot Start Taq allows reaction set up at room temperature while the temperature stable formulation guarantees optimal performance even if the mix is left at room temperature for extended periods.

Just add primers and DNA targets to the mix, and then proceed to amplification.  qMAX™ Gold is compatible with all real time thermal cyclers and exhibits high sensitivity with normal or fast 2-step cycling protocols.

Cas9 Nuclease 
Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated (Cas) systems provide bacteria and archaea with adaptive immunity against viruses and plasmids by using CRISPR RNAs (crRNAs) to guide the silencing of invading nucleic acids. The CRISPR system consists of a short non-coding guide RNA (sgRNA) made up of a target complementary CRISPR RNA (crRNA) and an auxiliary transactivating crRNA (tracrRNA). The sgRNA guides the Cas9 endonuclease to a specific genomic locus via base pairing between the crRNA sequence and the target sequence, and cleaves the DNA to create a double-strand break. The location of the break is within the target sequence 3 bases from the NGG PAM (Protospacer Adjacent Motif). The PAM sequence, NGG, must follow the targeted region on the opposite strand of the DNA with respect to the region complementary sgRNA sequence (Fig.1).

Intact Genomics Cas9 Nuclease is the purified recombinant Streptococcus pyogenes Cas9 enzyme containing a nuclear localization signal (NLS) at the C-terminal for targeting to the nucleus. This enzyme is designed to perform CRISPR/Cas9-mediated genome editing. The physical purity of this enzyme is â¥98% as assessed by SDS-PAGE with Coomassie® blue staining.
