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™ 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™ 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.
