Evaluation of injection methods for fast, high peak capacity separations with low thermal mass gas chromatography.
J. Chromatogr. A. 1392 , 82-90, (2015) Low thermal mass gas chromatography (LTM-GC) was evaluated for rapid, high peak capacity separations with three injection methods: liquid, headspace solid phase micro-extraction (HS-SPME), and direct vapor. An Agilent LTM equipped with a short microbore capil... |

Stabilization of proteins by solvents. Effect of pH and anions on the positive cooperativity of 2-nonanone binding to bovine serum albumin.
J. Biol. Chem. 255(18) , 8503-8, (1980) The binding of 2-nonanone to bovine serum albumin exhibited positive cooperativity at low molal ratios of binding, indicating stabilization of the hydrophobic binding sites at low concentrations of 2-nonanone. The degree of cooperativity was affected by the t... |
