PR1MA™ RNase Inhibitor

PR1MA™ RNase Inhibitor (RI) is a 50 kDa protein that specifically inhibits RNases A, B, and C by binding noncovalently in a 1:1 ratio at high affinity. It can be used in isothermal amplification and molecular diagnostic assays, cDNA synthesis, and other applications where RNA stability is important. It is ineffective against RNase1, T1, S1 Nuclease, or RNase H. It has no inhibition of polymerase activity when used with Taq DNA polymerase, AMV, M-MuLV, HIV reverse transcriptases, or phage RNA polymerases.

Storage Buffer

• 50% glycerol
• 10 mM Tris-HCl
• 50 mM KCl
• 8 mM DTT
• pH = 7.5 

*To prevent the release of ribonuclease from RNase Inhibitor, temperatures greater than 50°C and high concentrations of denaturing reagents such as urea should be avoided.

PR1MA™ Taq DNA Polymerase 1X Master Mix

PR1MA™ DNA polymerase 1X Master Mix saves time and cost by enabling direct PCR amplification of unpurified templates. It contains a recombinant, truncated (lacks 5’ to 3’ exonuclease activity), highly thermostable DNA polymerase from the thermophilic bacterium Thermus aquaticus. The enzyme is thermostable up to 98°C for polymerase chain reaction assays and is provided as a complete reaction master mix consisting of reaction buffer, dNTPs, MgCl2, and loading dye and only requires the addition of primers and DNA template. Once PCR is complete, the reaction products can be loaded directly into an agarose gel for analysis.

• Lacks exonuclease activity
• Thermotolerant up to 98°C
• Inhibitor Resistant
• Ideal for colony PCR, genotyping, and GC-rich templates
• Storage temperature: -20°C 

Important note: Please be sure to use the buffer provided with this product to ensure optimal results.

PR1MA™ β - Agarase

PR1MA™ β - Agarase has a high tolerance to inhibitors in electrophoretic buffers such as TBE and TAE, eliminating the need to perform a buffer exchange step before digestion. PR1MA™ β - Agarase has higher thermal stability than other commercially available β - agarases, with a broad range of activity between 42°C and 50°C. Higher temperature digestion reduces the chances of residual agarose gelling at the end of the reaction, resulting in higher recovery of DNA or RNA.

Benefits

• Complete digestion of agarose, with no agarose fragments, left after the digestion
• Obtain DNA or RNA faster - no buffer exchange needed, with direct digestion in TAE or TBE
• Concentration: 1000 u / mL
• Operating temperature: 42°C to 50°C
• Recommended temperature: 50°C
• Storage temperature: -20°C 

Storage Buffer

• 50% glycerol
• 50 mM Tris-HCI
• 50 mM KCI
• 1 mM DTT
• 0.1  mM EDTA
• pH = 7.5 

*These products are intended for research use only, not for therapeutic or diagnostic purposes in humans or animals. The safety and efficacy of these products in diagnostic or other clinical uses has not been established.

Azure HRP Stripping Buffer

Works by removing the primary and secondary antibodies from the membrane

Stripping buffer for stripping and re-probing chemiluminescent Western blots.

• Provided as a 1x ready-to-use solution
• Size: 500mL

Azure Chemi Blot Blocking Buffer

This Chemi Blot Blocking Buffer was formulated to enhance signal and lower background by improving sensitivity. Enhances specific antibody-antigen interactions specifically for chemiluminescent Western blots. 

• Provided as a 1x ready-to-use solution- no mixing or dilutions required.
• Size: 500mL

Features

Western blot membranes should be incubated in blocking buffer before antibody hybridization to prevent non-specific binding of antibodies. Blocking buffer can also be used for diluting primary and secondary antibodies during hybridization.

Azure Blot Washing Buffer

Wash buffers are an important part of the blotting process for removing unhybridized antibody and preventing background signal.

Blot washing buffer for use with Azure Imaging Systems, or any other Western blotting system.

• Provided as a 10x concentrated solution
• Size: 500mL

NOTE: While this Blot Washing Buffer is compatible with NIR Fluorescent Western blots, for the best results with NIR fluorescence, we recommend the Azure Fluorescent Blot Washing Buffer.

Azure Protein-free Blot Blocking Buffer

Protein-free blocking solution optimized for fluorescent Immunoblots and Western blots

Does not contain proteins. Azure Protein-Free Blot Blocking Buffer can reduce background in Western blots where the primary antibodies tend to cross-react with protein blockers like BSA, casein or milk protein. For low-quality primary antibodies that may require protein-based blocking agents, BSA or non-fat dry milk can be dissolved directly in the Azure Protein-Free Blot Blocking Buffer and then used to dilute the antibody.

Best used with assays where animal-based product usage is prohibited. Serves as an excellent blocking reagent for chemiluminescent Western blotting.

• Provided as a 5x solution
• Size: 200mL

Azure Transfer Buffer

This proprietary transfer buffer provides improved detection of low-abundance and post-translationally modified proteins.

High-efficiency protein transfer and increased protein retention on the membrane add up to more sensitive Western blots.

• Provided as a 50x concentrated solution. Sufficient for 50-100 blots
• Size: 500mL

Features

• High performance—increased protein retention on the membrane and fast transfer times result in more sensitive detection of low-abundance and post-translationally modified proteins
• Efficient—enhanced transfer efficiency for proteins of all sizes
• Fast—transfer proteins in less than 20 minutes vs. several hours required with traditional transfer buffers
• Convenient—use your existing wet transfer electrophoresis apparatus
