Background & Development of Anapoe® EH-9
Polyoxyethylene (POE) detergents have been instrumental in structural biology. Overall, around 10% of membrane proteins of known structure were solubilized in these detergents before successful structural work . Moreover, a similar percentage of membrane protein structures were solved using POEs as part of structure determination conditions (predominantly structures solved by X-ray diffraction) . They allowed scientists to determine crystal structures of beta-barrel proteins, large respiratory complexes, and ABC transporters, as well as other proteins [2,3].
POEs are depicted by chemical formulas of the general type CxEy (C8E4 to C12E14 and beyond, where x is the length of the alkyl chain and y is the quantity of oxyethylene units). A few popular names in this class are Triton, Tween, Genapol, Brij, Thesit, and Lubrol. POEs show a range of CMC, micelle sizes, and surfactant properties: from harsher (e.g. C8E4) to milder (e.g. C12E14) . POE detergents require purification of industrial mixtures, whose quality may vary from batch to batch. As POEs contain ether-linked headgroups, they can accumulate peroxides as a common contaminant over a period of time. Peroxides could disturb the tertiary structure of proteins and potentially interfere with native protein folding, which could lead to inactivation or disintegration of the desired macromolecule. Industrial-grade POEs contain hydrogen peroxide as high as 0.2%w/w, and these levels can significantly increase with time upon exposure to light, heat and/or oxygen in the air.
To combat these problems, Anapoe® EH-9 reagents were crafted by purifying respective industrial grade detergents to contain less than 20 µM of equivalent peroxide. It is supplied as a 10% aqueous solution and packed under an inert gas to assure added stability. Anapoe® EH-9 detergents are prepared and enhanced so you get the functionality you need, without the side effects.
Anatrace is amplifying its successful Anapoe® portfolio with a new product, Anapoe® EH-9 (APEEH9). It is purified from ECOSURF™ EH-9, which is compliant with ecological regulations concerning biodegradability . The product is tested to meet our high standards of less than 20µM peroxides. And we bring it at an affordable price in a variety of package sizes!
