PR1MA Taq

  • Ideal for routine PCR applications as well as genotyping, colony PCR, and fast PCR
  • Improved template affinity and solubility for higher enzyme activity and greater yields
  • Proprietary buffer optimized for a variety of assay conditions
  • Conveniently supplied as a 2X Master Mix or in a 2-tube format of polymerase and separate 5X buffer

 

PR1MA Taq provides superior results for routine applications. Modified to improve DNA-binding, this polymerase offers higher solubility and greater template affinity, resulting in consistently superior performance. PR1MA Taq Polymerase exhibits a 5' to 3' nuclease activity, but no 3' to 5' (proofreading) activity and works well with a wide range of DNA templates including GC-rich sequences.

 

The polymerase is supplied with a 5X buffer containing MgCl2 and a proprietary mix of enhancers (dNTP's not included). For convenience, PR1MA Taq is also available in a ready-to-use 2X Master Mix - just add primers and template DNA. Our "Red Dye" Master Mix incorporates a red-loading dye that allows amplified samples to be loaded directly on an agarose gel.  The red color aids in visualization during pipetting, and higher density of the buffer ensures that the samples will drop into the gel wells.

PR1MA SmartGlow DNA Safe Stain

  • Replaces hazardous Ethidium Bromide (EtBr)
  • Better sensitivity than EtBr
  • Detect as little as 0.1ng of DNA
  • Two types available
  • PS Pre Stain
  • LD Loading Dye
  • Excitation by UV light or blue light
  • Compatible with Accuris SmartBlue Transilluminator
  • Ships at ambient temperature (stored at 4°C)

PR1MA SmartStain PS (Pre-Stain) can be used as a direct replacement for Ethidium Bromide in agarose and polyacrylamide gel electrophoresis. The stain emits green fluorescence when bound to dsDNA or ssDNA and emits red fluorescence when bound to RNA. PR1MA SmartStain PS exhibits excitation peaks at 290 nm and 490 nm, allowing it to be used with UV and blue light.

Protocol:

  • Prepare 100 mL of agarose or polyacrylamide solution.
  • Add 5 uL of PR1MA SmartStain to the gel solution before pouring gels.
  • For enhanced results, add PR1MA SmartStain PS to the running buffer at a ratio of 5 uL per 100 mL. Adding PR1MA SmartStain PS to the running buffer will result in increased sensitivity and better detection of small quantities of nucleic acid.
  • After electrophoresis is complete, view the gel using a UV or blue light illuminator

PR1MA
One-Step RT-PCR Kit

  • Convenient cDNA synthesis and PCR in a single tube from 1 pg total RNA
  • Formulated for highly specific and sensitive RT-PCR from any RNA templates
  • Incorporates thermostable reverse transcriptase and Hot-Start Taq for preparation at room temperature

The PR1MA One-Step RT-PCR Kit has been formulated for cDNA synthesis and subsequent PCR in a single tube for end-point analysis. This latest generation RT-PCR Kit consists of an MMLV-derived, thermostable Reverse Transcriptase (45°C to 55°C), an advanced RNase Inhibitor and PR1MA Hot Start Taq for ultra-sensitive one-step RT-PCR from as little as 1pg total RNA starting material.

The optimized buffer chemistry allows for efficient reverse transcription and PCR of problematic sequences with significant secondary structure (such as GC-rich targets). The PR1MA One-Step RT-PCR Kit is ideal for determining the presence or absence of RNA templates and quantifying expression through qualitative analysis of RNA transcription levels. The kit also efficiently synthesizes double-stranded cDNA for subsequent gene expression analysis.

 cDNA Synthesis Kits

PR1MA now offers two cDNA Synthesis Kits, to meet a range of requirements.
 

The original cDNA Synthesis Kit is a 2-tube format for easy reaction setup and is ideal for 4 pg to 0.5 µg of input RNA. One tube includes our exceptionally stable Reverse Transcriptase combined with a potent RNAse inhibitor, and the other tube contains a 5X reaction buffer with an optimal mixture of anchored oligo (dT) primers and random hexamers to produce a non-biased population of cDNA. 
 

The 1st Strand cDNA Synthesis Flex Kit includes four components: a high-capacity Reverse Transcriptase, an optimized 5X buffer, separate solutions of oligo (dT) primers, and random hexamer primers. This multi-component format is ideal for 10 pg to 2.0 µg of input RNA and allows for greater flexibility in assay design.

PR1MA dNTPs

  • Supplied as a ready-to-use 40 mM mix or a set of 4 separate 100 mM solutions
  • Free of impurities and inhibitors that reduce sensitivity and yield
  • No nuclease, protease or nickase activity
  • >99% pure, purified by HPLC
  • 24-month shelf life

PR1MA dNTP's are purified by HPLC in a strict process that results in greater than 99% purity. The stringent purification process eliminates PCR inhibitors such as tetraphosphates and pyrophosphates that can interfere with the sensitivity of your PCR and reduce yields.
The 40 mM dNTP Mix is a single tube that contains premixed dNTPs at a concentration of 10 mM each. The 100 mM dNTP Set contains four individual tubes, one each of dATP, dCTP, dGTP and dTTP. The nucleotides are supplied in ultra-pure water as an ammonium salt. Both the set and mix are stable for 24 months when stored at -20ºC.

Extensive quality control testing is performed to ensure the dNTPs are free of nuclease, protease and nickase activity. Each lot is performance tested in standard PCR, long PCR and qPCR reactions to assess reproducibility and sensitivity.

 PR1MA Hot Start Taq

  • Exceptional sensitivity for low-copy PCR
  • Ideal for multiplex PCR and amplification of GC-rich DNA
  • Same enhanced features as PR1MA Taq Polymerase
  • Buffer optimized for fast cycling and reproducibility 

Engineered for controlled polymerase activity, PR1MA Hot Start Taq is bound with a monoclonal antibody that blocks enzyme activity. This allows reactions to be set up at room temperature without the risk of non-specific amplification.

 

When samples are ready, the reaction mixture is heated to 95°C to denature the antibody and initiate the reaction. Similar to the standard PR1MA Taq, Hot Start Taq is provided with a 5X buffer, or in a ready-to-use 2X Master Mix. The Master Mix can be ordered with or without an incorporated red gel loading dye. The Red Dye Master Mix incorporates a red-loading dye that allows amplified samples to be loaded directly on an agarose gel.  The red color aids in visualization during pipetting, and higher density of the buffer ensures that the samples will drop into the gel wells.
