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.

IBI Cell Culture Grade, Pyrogen/Endotoxin Free Water is prepared for nuclear transfer, transfection, transformation, cell and tissue culture,
LAL testing, and all other aqueous solution preparations that require stringent quality control.


IBI Cell Culture Grade Water is tested for use in critical assays and applications. The water is endotoxin-free (to the maximum detection
limit of <0.005EU/ml by turbidimetric assay). The purification process of our Cell Culture Grade Water includes distillation, continuous
deionization, reverse osmosis, 0.1µm filtration, followed by steam sterilization in an autoclave.

  • RNase & DNase Free Water A new process of purifying large quantity of DNase and RNase free water enables us to offer Molecular Grade Water at a price that any laboratory can afford. 

  • No toxic agents such as DEPC are used in making the Molecular Grade Water; therefore, there is no chance of DEPC interfering with enzymatic reactions. 

  • The Molecular Grade Water is suitable for use in molecular biology applications which demand a high quality of water and assurance that the water is free from DNase and RNase contamination. 

  • Molecular Grade Water can be used for making reagents and rinsing glass/plastic wares for DNA and RNA research. 

  • Each lot is quality tested for the absence of RNase and DNase contamination. Test reports are attached with each container as an added assurance.
