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™ qMAX Green qPCR Mix with Blue Tracking Dye
PR1MA™ qMAX Green qPCR Mix with Blue Tracking Dye
- Superior sensitivity and fast cycling with exceptional results
- Ideal for low copy number templates
- Early Ct values and detection across a broad dynamic range
- Ready to use 2X Master Mix
- Includes PR1MA™ Hot Start Taq Polymerase for greater specificity and accuracy
Supplied as a ready-to-use 2X master mix, PR1MA™ qMax Green has been engineered for high sensitivity, fast cycling, and excellent reproducibility. PR1MA™ Hot Start Polymerase provides accurate PCR of a variety of templates including low copy number and difficult sequences, while the proprietary qMax Green intercalating dye exhibits higher fluorescence and lower PCR inhibition than other popular green dyes.
These two components are supported by a specially formulated buffer with an exacting combination of salts, PCR enhancers, stabilizers, and pH that results in earlier Ct values and a high specificity across a broad dynamic range.
