Separation of bile acids from neutral lipids on thin-layer chromatograms
(Elsevier, 1974-11-13)
Structural studies of capsular polysaccharide of type XII diplococcus pneumoniae
(Elsevier, 1974-10)
The capsular polysaccharide of Diplococcus pneumoniae Type XII contains residues of -glucose and -galactose in a molar ratio of 2:1. The methylated polysaccharide yielded upon hydrolysis 2,3,4,6-tetra- and 3,4,6-tri-O-me ...
Fluorescein isothiocyanates: Improved synthesis and purity : Spectral studies
(Elsevier, 1974-01)
Modification of the methods of synthesis by direct reaction of the isomeric aminofluoresceins with a limited excess of thiophosgene in the presence of calcium carbonate has yielded the 5- and 6-isothiocyanatofluoresceins ...
A two-step procedure for purification of papain from extract of papaya latex
(Elsevier, 1974-09)
A method is presented for purifying papain from extracts of papaya latex. The procedure involves precipitation of the extract of papaya latex with sodium chloride followed by affinity chromatography of the redissolved ...
The purification and properties of an alcohol dehydrogenase from mouse liver
(Elsevier, 1974-04)
1. 1. An alcohol dehydrogenase (alcohol: NAD oxidoreductase, EC ( [middle dot] [middle dot] ) was isolated from the supernatant fraction of mouse liver and purified 206-fold.2. 2. A number of aliphatic aldehydes, ranging ...
Partial characterization of dinoflagellate chromosomal proteins
(Elsevier, 1974-05-31)
Dinoflagellate chromosomal proteins were analyzed by acrylamide gel electrophoresis. The electrophoretic pattern of acid-insoluble chromosomal proteins from Gyrodinium cohnii in sodium dodecylsulfate gels is less heterogeneous ...
Amino acid sequence of sheep carbonic anhydrase C
(Elsevier, 1974-12-18)
The sequence of amino acid residues comprising the major form of sheep red cell carbonic anhydrase C has been determined. The primary sequences of peptides derived from cyanogen bromide cleavage and tryptic digestion were ...
Complexity in valinomycin effects on amino acid transport
(Elsevier, 1974-02-26)
3H-labeled dibenzyldimethylammonium ion, applied as an indicator for the potential differences across the plasma membrane, enters the Ehrlich ascites-tumor cell during 2 h to an apparent steady-state concentration about ...
Facilitated transport via carrier—mediated diffusion in membranes: Part II. Mathematical aspects and analyses
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1974-07)
Part II of this review is concerned with the mathematical analysis of facilitated transport. An exposition is given of the most generally useful techniques for obtaining asymptotic or approximate solutions to one-dimensional ...
