Molecular Biology Reagents/Chemicals
MIDSCI™ gives you ultra-pure, cost-competitive molecular biology reagents and lab chemicals for life science research; often with significant cost savings over Sigma Aldrich and other lab reagent providers.
PR1MA™ Chemicals can help with a wide variety of research-based requirements.
Use our glycerol for polyacrylamide gel electrophoresis. Eliminate Agrobacterium after inoculation with the carbenicillin we carry. Or detect β-Galactosidase activity with X-GAL which, when combined with the IPTG we stock, can be used to detect lac gene expression in cloning applications.
We also carry Luria Broth (Lennox), for the propagation and maintenance of E. coli; DTT, in order to maintain –SH groups in a reduced state; and high gel strength agar for tissue culture and microbiological work.

PR1MA™ Mammalian Genotyping Kit
- DNA extraction and amplification in 1 hour
- Proprietary lysis buffer optimized for ear punches, tail snips and other mammalian tissues
- Single tube - no organic solvents or clean up procedures
- Enhanced PR1MA™ Hot Start Polymerase included
Traditionally, mammalian genotyping protocols have involved Proteinase K digestion, neutralization, organic extraction and lots of hands on time to get PCR-ready DNA.
The PR1MA™ Mammalian Genotyping Kit is quick and easy to use - add sample to the proprietary lysis buffer and incubate for 5-10 minutes, then add the deactivation buffer and incubate for 10 minutes. The crude lysate can then be amplified using fast PCR PR1MA™ Hot Start Taq Master Mix with red loading dye (included). The kit contains everything needed - just add sample and primers.

Accuris qMAX™ One-Step RT-qPCR kits
- RNA to cDNA to qPCR, in one tube
- High purity enzyme formulation for enhanced stability and performance
- Accuris Hot-Start Taq allows for preparation at room-temperature
- Blue dye facilitates pipetting and visualization in plates
- Available for green fluorescence or probe detection
- Multiplex formulation available for multiple target amplification
- Bulk pricing available for high throughput labs and kit manufacturers contact us for details
Accuris qMAX™ One Step Kits allow for highly sensitive real time RT-qPCR assays to be performed directly from RNA templates. Workflows are simplified with optimized formulations of ready-to-use 2X qPCR master mix and 20X reverse transcriptase.
Optimized buffer includes powerful RNase inhibitors, and an extremely thermostable MMLV-derived reverse transcriptase enables robust first strand cDNA synthesis. Accuris Hot Start Taq uses an antibody mediated hot start mechanism allowing for sample preparation at room temperature. Only after an initial incubation at 95C will the Taq become active, so non-specific amplification is greatly reduced. An inert blue dye is included in the Taq master mix to help simplify pipetting and reduce errors.
Three versions of our One Step qPCR kits are available:
qMAX™ Green One Step kits incorporate our proprietary intercalating dye which exhibits higher fluorescent and lower PCR inhibition than other popular dyes such as SYBR.
qMAX™ Probe One Step kits are optimized for use with popular TaqMan™, Scorpions, and molecular beacon probes.
qMAX™ Probe One Step Multiplex kits are specifically developed and optimized for efficient probe-based detection of multiple targets in a single reaction well. The Multiplex formulation is comprised of a 20x reverse transcriptase and 2x PCR Mix preparation ideally suited for complex RNA samples including low-copy number viral RNA commonly used in the clinical and research laboratory. qMAX Probe One Step Multiplex kits have been designed to overcome the many challenges of multiplex RT-PCR, by addressing important factors such as the balance between magnesium chloride and deoxynucleotide concentrations, the relative Taq Polymerase and reverse transcriptase concentration, and the ionic conditions of the core reaction buffer.
All Accuris One-Step Kits are compatible with standard and fast cycling
protocols and provide increased sensitivity, speed, and reproducibility for
a broad range of samples and targets. The polymerase mix is available with
different levels of ROX reference dye for compatibility with all qPCR
instruments.

PR1MA™ Cod Uracil-DNA Glycosylase
PR1MA™ Cod Uracil-DNA Glycosylase (cUNG) is a recombinant, thermolabile enzyme that removes uracil from DNA. It is ideal for preventing carry over contamination during RNA or DNA amplification reactions that substitute dUTP for dTTP. cUNG is the only commercially available UNG that is completely and irreversibly inactivated by moderate heat treatment, unlike bacterial versions of the enzyme. Cod UNG treatment in combination with targeted pre-amplification using dUTP provides a simple and efficient solution to eliminate carry-over contamination and the generation of false positives and inaccurate quantification.
- Optimal temperature: 37°C
- Heat inactivation: 55°C for 5 minutes
- Enables contamination control in PCR and other amplification methods
- Does not degrade product after inactivation, enabling downstream use of the amplicon
