• 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.

ig-Fusion Cloning Kit 
Intact Genomics propriety ig-Fusion cloning technology is a simple, rapid and highly efficient cloning kit which allows to directly clone any PCR product(s) to any linearized expression vector at any site. The PCR fragments can be generated by Intact Genomics high fidelity Pfu DNA polymerase or other high-fidelity DNA polymerases, with primers having 15 to 18 bases of homology at their linear ends to where the product need to fuse. The linearized vector can be generated by PCR or restriction enzymes. The kit is so robust that multiple DNA fragments can be assembled simultaneously and cloned into one construct in a single reaction step within short times (usually 10-30 min) with more than 95% cloning efficiency.

Benefits

• Clone any insert at any site within any vector
• Restriction enzyme and phosphatase free system
• Joining multiple large fragments at once
• Precise insertion at a desired orientation
• Rapid and high efficiency with > 95% positive clones

Bullseye EasyScript cDNA Synthesis Kit

Application

• First strand cDNA synthesis for PCR
• Construction of cDNA libraries
• Generation of probes for hybridization

EasyScript cDNA Synthesis Kit is a complete system for the efficient synthesis of first strand cDNA from RNA templates. The recombinant RNasin Ribonuclease Inhibitor, supplied with the kit effectively protects RNA template from degradation.

The kit is also supplied with both oligo(dT) and random primers. The oligo(dT) anneals selectively on the poly(A) tail of mRNA. Random primers do not require the presence of poly(A). Therefore, they can be used for transcription of the 5'-end regions of mRNA. Gene-specific primers may also be used with the kit. The first strand of cDNA can be directly used as a template in PCR.

EasyScript Reverse Transcriptase (RTase) within the kit 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 host 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 random primer 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.
