Some Researches on Histones

The histone extracted from calf thymus glands is a complex system of proteins, which can be fractionated by chromatography on carboxymethyl cellulose columns into three principal fractions (1) very lysine-rich, (2) moderately lysine-rich, (3) arginine-rich. When examined by starch gel chromatography each of these gives more than one band. Methods have been devised for further separation of the ...

New extraction method of THC and its metabolites, 11-OH-THC and THC-COOH, in plasma

Objectives: A liquid/liquid extraction technique on solid support of Δ9-tetradydrocannabinol (THC), 11-hydroxy-Δ9-tetradydrocannabinol (11-OH-THC) and 11-nor-Δ9-tetradydrocannabinol-9-carboxylic acid (THCCOOH) in plasma was developed in order to be assayed by high-performance liquid chromatography and tandem mass spectrometry (HPLC-MS/MS). Methods: The samples were extracted by liquid/liquid ex...

Effects of Coagulation Conditions on Properties of Multifilament Fibers Based on Dissolution of Cellulose in NaOH/Urea Aqueous Solution

Effects of coagulation temperature, coagulants, and wet-spinning methods on structure and properties of novel regenerated cellulose (RC) fibers prepared from cellulose in 7.5 wt % NaOH/11 wt % urea aqueous solution on pilot scale spinning machine by oneand two-stage coagulation were investigated by tensile testing, optical microscopy, scanning electron micrograph, and wide-angle X-ray diffracti...
