pH-zone-refining countercurrent chromatography.
A recently developed preparative technique, pH-zone-refining countercurrent chromatography (CCC), separates organic acids and bases according to their pKa and hydrophobicity. The hydrodynamic mechanism of pH-zone-refining CCC is illustrated in two elution modes along with a simple mathematical analysis. Separations include acidic and basic derivatives of amino acids and peptides, hydroxyxanthen...
متن کاملPurification and Characterization of Human Coagulation Factor
We have purified human coagulation Factor V 6,000fold to homogeneity from citrated plasma using polyethylene glycol 6000 precipitation, adsorption of Factor V to barium citrate, DEAE-Sepharose chromatography, and gel filtration on Ultrogel AcA 34 (yield 21%). Human Factor V is a single polypeptide chain before and after disulfide bond reduction with an apparent M, = 335,000 as determined by ele...
متن کاملPartial Purification and Characterization of Anticoagulant Factor from the Snake (Echis carinatus) Venom
Objective(s): Snake venoms contain complex mixture of proteins with biological activities. Some of these proteins affect blood coagulation and platelet function in different ways. Snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. In the present study, purification of anticoagulation facto...
متن کاملAtrial natriuretic factor. Characterization and partial purification.
One of the main differences between atrial and ventricular cardiocytes is the presence in former of specific granules with morphological characteristics very similar to secretory granules found in peptide-secreting endocrine cells. It has been suggested that these granules are the storage place for the atrial natriuretic factor. In the rat, water deprivation produces an increase in atrial granu...
متن کاملRefining the Definition of BPD: Characterization of Intercurrent Episodes
Background: The main definitions of bronchopulmonary dysplasia (BPD), proposed by Jobe-Bancalari, Shennan et al., and Walsh et al., focus on oxygen (O2)-need and ventilatory support for the first weeks of life and at 36 weeks of post-menstrual age (PMA). Oxygen need at 36 weeks of PMA is sometimes due to intercurrent episodes (IEs) other than BPD. The aim of this retrospective study was to char...
