설명

General description

Potassium phosphate monobasic (monopotassium orthophosphate) is a water soluble inorganic salt. Its standard enthalpy of formation has been reported to be −376.1 kcalmol^-1. It acts a starting material in the synthesis of potassium metaphosphate.

Redi-Dri^™ technology eliminates clumping and the need for complicated procedures to keep your salts free-flowing. Keeping your salts dry helps improve your results by giving accurate measurements and easier-to-handle salts and buffers. Rather than drying your salts in an oven or desiccator or breaking them apart manually, Redi-Dri^™ ensures that your salts will remain easy-to-use for months without worrying about anti-caking agents. Even after repeated openings you can be assured that your results are always accurate. Redi-Dri^™ saves you time, energy and money by keeping your salts usable for longer!

Application

Potassium phosphate monobasic has been used in the preparation of phosphate buffer and phosphate buffered saline (PBS). It has also been used in the preparation of PEG1000 (polyethylene glycol)/potassium phosphate aqueous two-phase systems (ATPS).

Features and Benefits

Increased efficiency – Eliminate time and effort of loosening hardened powders
Safety – Avoid risks of using tools of force to break up clumps
Economy – Faster preparation and solvation increase productivity and reduce costs
Assured quality – Excellent, expert-tested quality with no anti-caking agents
Flexible volumes – Available from research amounts to scale-up quantities

Redi-Dri™ – The World of Free-flowing Hygroscopic Products

Redi-Dri™ prevents hygroscopic powders, such as inorganic salts, from absorbing moisture and forming clumps, leaving the salts free-flowing every time.

Neuroprotection of the Developing Brain by Dexmedetomidine Is Mediated by Attenuating Single Propofol-induced Hippocampal Apoptosis and Synaptic Plasticity Deficits.

Wenchong Sun et al.

Experimental neurobiology, 29(5), 356-375 (2020-11-07)

Dexmedetomidine (DEX) has neuroprotective effects and its efficacy was determined in propofol-treated pups. Postnatal day (P) 7 rats were exposed to propofol and DEX to investigate the induced apoptosis-related gene expression. Furthermore, synaptic structural changes at the cellular level were

Genetic circuit design automation for the gut resident species Bacteroides thetaiotaomicron.

Mao Taketani et al.

Nature biotechnology, 38(8), 962-969 (2020-04-02)

Bacteroides thetaiotaomicron is a human-associated bacterium that holds promise for delivery of therapies in the gut microbiome1. Therapeutic bacteria would benefit from the ability to turn on different programs of gene expression in response to conditions inside and outside of

Natural killer cells contribute to mitochondrial dysfunction in response to placental ischemia in reduced uterine perfusion pressure rats.
