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.

IBI Ethanol (Anhydrous Alcohol)

 

Introducing our premium-grade Ethanol, also known as Anhydrous Alcohol – the versatile solution for a myriad of applications. Sourced and refined with meticulous care, our Ethanol stands as a hallmark of purity and quality, ready to meet your diverse needs.

 

Our Ethanol is widely used for precipitating nucleic acids. The nucleic precipitate, which is formed in the presence of moderate concentrations of monovalent cations, is recovered by centrifugation and re-dissolved in an appropriate buffer at the desired concentration.

 

200 Proof Ethanol is denatured with methyl alcohol. It is also known as ethyl alcohol, alcohol anhydrous, denatured alcohol.
