High impact information on Chemical Fractionation

• The new histones have been identified as a new F1 (TF1) and F2b (TF2b) on the basis of their behavior upon chemical fractionation procedures and electrophoresis at several urea concentrations [1].
• Chemical fractionation revealed that ca. 98% of the labeled cholesterol was associated with the cell membrane(s) [2].
• Chemical fractionation of the extracts revealed that the majority of the dioxin-receptor binding activity from urban air and gasoline vehicle samples fractionated with the polycyclic aromatic compounds [3].
• Chemical fractionation showed that H2O-extractable P was the predominant form in broiler litter (56-77%), whereas aqueous phosphate determined with XANES was <18% indicating that H2O probably dissolved mineral forms of P (e.g., dicalcium phosphate) [4].
• Iodine-129 and caesium-137 in Chernobyl contaminated soil and their chemical fractionation [5].

Biological context of Chemical Fractionation

• Identification of Lilial as a fragrance sensitizer in a perfume by bioassay-guided chemical fractionation and structure-activity relationships [6].
• This method may be used to avoid chemical fractionation using agents such as ethanol or PEG and, thus, decrease protein denaturation of the different fractions to be used for research or pharmaceutical purposes [7].

Associations of Chemical Fractionation with chemical compounds

• Computer-assisted recognition of these profiles was followed by a rapid chemical fractionation, thus permitting the efficient dereplication of those extracts containing cucurbitacins B [3] and D [4], respectively [8].
• Total metal analyses, sequential chemical fractionation, and DTPA extractions were carried out on samples of control and sludge-amended pedons in Nigeria (a Rhodic Kandiustult and two Rhodic Kandiustalfs from Nigeria, respectively) [9].
• The chemical fractionation of Mn, Al, Zn, Cu and Ti was investigated using a five-step sequential extraction procedure employing KNO3, KF, Na4P2O7, EDTA and HNO3 [10].
• The chemical fractionation of these elements was also determined by a sequential leaching procedure, using deionized water, NH4OAC and HCI as extracting agents [11].
• The bioassay-guided chemical fractionation of this extract afforded the sesquiterpene dialdehyde polygodial as the active constituent [12].

Gene context of Chemical Fractionation

• The emphasis is upon the first discovered of these, bone morphogenetic protein (BMP) and a protein which copurifies with BMP in the initial steps of chemical fractionation [13].
• Results for copper, lead and zinc chemical fractionation of peat profiles from Ringinglow Bog, near Sheffield, Great Britain, are reported and discussed [14].

Analytical, diagnostic and therapeutic context of Chemical Fractionation

• The distribution of 203Hg in Saccharomyces cerevisiae grown in the presence of mercuric chloride has been examined by physical and chemical fractionation procedures and autoradiography [15].
