• 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

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.

Bullseye PREMIUM HS-Taq DNA Polymerase Master Mix Blue

HS Taq Polymerase Master Mix BLUE is a ready to use 2 X master mix. Simply add primers, template and water to successfully carry out primer extensions. The master mix is available in 100, 500, 1000, and 2500 reaction sizes and is available with two different buffer options (HS Buffer 1 and HS Buffer 2)

HS Taq Polymerase is a modified form of Bullseye Taq, activated by heat treatment. This results in higher specificity and greater yields when compared to standard Taq.

Bullseye PREMIUM GC Rich Optimized DNA Polymerases and Kits

General Description
Bullseye GC HS 2x Master Mix II is an all-in-one 2x master mix containing HS DNA polymerase, GC Buffer II, enhancer, dNTPs and MgCl. Simply mix GC HS 2x Master Mix II with primers,template and water and you are ready to carry out successful primer extensions. HS DNA Polymerase is a modified form of Bullseye Taq DNA polymerase, which is activated by heat treatment. A chemical moiety is attached to the enzyme at the active site, which renders the enzyme inactive at room temperature. Thus, during setup and the first ramp of thermal cycling, the enzyme is not active and misprimed primers are not extended. The result is higher specificity, increased sensitivity and greater yields when compared to standard DNA polymerases.
