Epimerization of trans-4-hydroxy--proline to cis-4-hydroxy--proline during acid hydrolysis of collagen
(Elsevier, 1972-10)
1. 1. trans-4-Hydroxy--proline is epimerized to cis-4-hydroxy--proline under the conditions generally used for the hydrolysis of proteins for analyses of amino acids.2. 2. The cis epimer elutes from a column of UR-30 resin ...
Immunochemical studies on methyl [alpha]- and methyl [beta]-glucosaminide-azoprotein conjugates
(Elsevier, 1976-09)
Conjugates consisting of methyl 2(p-azobenzamido)2-deoxy-[alpha]--glucopyranoside and methyl 2(p-azobenzamido)-2-[beta]--glucopyranoside coupled to bovine serum albumin were used as synthetic antigens. Rabbits immunized ...
Correlation between serum enzymes, isozyme patterns and histologically detectable organ damage
(Elsevier, 1971)
Serum enzyme levels and isozyme profile were utilized as a measure of hepatotoxic response to carbon tetrachloride, mercuric chloride, diethanolamine and thioacetamide. The sensitivity of these measurements was compared ...
Exploding wire excitation for trace analysis of Hg, Cd, Pb and Ni using electrodeposition for preconcentration
(Elsevier, 1973-12)
The use of exploding silver wires for spectrochemical excitation is described. The apparatus used in these studies is discussed along with the electrical and radiative properties of exploding silver wires. The use of ...
Cholesterol biosynthesis in human fetal liver and adrenal
(Elsevier, 1971-07)
Hepatic and adrenal cholesterol biosynthesis were investigated in the human fetus in vitro by measuring the incorporation of acetate-2-14C into cholesterol by slices of liver and adrenals from the same fetus. To differentiate ...
An N-acetyl--glucosamine binding lectin from Bandeiraea Simplicifolia seeds
(Elsevier, 1976-11)
A second lectin with a high activity for nonreducing 2-acetamido-2-deoxy-[alpha]--glucopyranosyl residues has been isolated from the seed extracts of Bandeiraea simplicifolia by affinity chromatography on chitin. The lectin ...
A complete general valence force field for secondary chlorides
(Elsevier, 1973-12)
A general valence force field for secondary chlorides has been refined which includes torsional force constants based on assignments of low frequency modes in model compounds. This force field also incorporates force ...
