Simultaneous quantification of lyso-neutral glycosphingolipids and neutral glycosphingolipids by N-acetylation with [3H]acetic anhydride.
We describe a new method that permits quantification in the pmol to nmol range of three lyso-neutral glycosphingolipids (lyso-n-GSLs), glucosylsphingosine (GlcSph), galactosylsphingosine (GalSph), and lactosylsphingosine, in the same sample as neutral glycosphingolipids (n-GSLs). Lyso-n-GSLs and n-GSLs are initially obtained from a crude lipid extract using Sephadex G25 chromatography, followed...
متن کاملRadiolabeling of proteins and viruses in vitro by acetylation with radioactive acetic anhydride.
We describe a convenient, rapid, and reproducible method for labeling proteins in vitro by acetylation with [3H] or [14-C]acetic anhydride dissolved in small amounts of anhydrous dioxane. The reaction is carried out at neutral pH and does not require the use of detergents, water-immiscible organic solvents, oxidizing, or reducing agents. Thus undesirable solvent-induced alterations in protein s...
متن کاملMicrowave-assisted solvent-free acetylation of cellulose with acetic anhydride in the presence of iodine as a catalyst.
In this work an optimization of the solvent-free acetylation of cellulose with acetic anhydride under microwave heating with iodine as a catalyst was performed. The optimized parameters included the microwave irradiation power from 300 W to 800 W, the reaction time between 5 to 40 min, the reaction temperature from 80 to 130 degrees C, and the amount of iodine from 1 to 15 mol%. The extent of t...
متن کاملLabeling of high density lipoproteins with [3H] acetic anhydride.
Rat serum HDL was labeled by reaction with [3H] acetic anhydride at pH 7.2 for 30 min at room temperature by a modification of the method of Montelaro and Rueckert (1975. J. Biol. Chem. 250: 1413). Protein specific activities of 60 dpm/ng were achieved. Seven percent of the label was in lipid, of which 92 percent was recovered in phospholipid. The labeled HDL migrated as a single band as seen b...
متن کاملThe Racemization of Amino Acids in Aqueous Solution by Acetic Anhydride
In a previous investigation du Vigneaud and Sealock (1) have reported that the sodium salt of acetyl-l-tryptophane in aqueous solution at 35-40” is completely racemized by acetic anhydride within a few hours. The ease of racemization and particularly the mild conditions under which the reaction occurred seemed to us to offer an excellent method for racemizing amino acids if the reaction should ...
