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 ...
Rate-dependent effect of amphetamine in rats: Extension to between-subjects effect
(Springer-Verlag, 1976-01)
Following either variable-interval or fixed-interval training, 20 rats received both 0.5 and 2.0 mg/kg of amphetamine. For both schedules, amphetamine decreased response rates of high-rate subjects and increased those of ...
A reexamination of apomorphine induced stereotypy in the rat in light of self administration experiments
(Elsevier, 1979)
1. 1. Apomorphine is known to both elicit stereotypy and to support behavioral self administration. The present report examined a possible contribution of stereotypy to self administration.2. 2. Non-contingent intraperitoneal ...
