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 ...
Determination of anserine, carnosine, and other histidine compounds in muscle extractives
(Elsevier, 1971-01)
A method for the determination of anserine, carnosine, homocarnosine, histidine, 1-methylhistidine, and 3-methylhistidine with the Phoenix amino acid analyzer is described. A study of the separation of these compounds on ...
Nephrotoxic effects of tetanus toxin: An ultrastructural study
(Elsevier, 1975-12)
Generalized nephrotoxicity was observed in the rat as early as 6 hr after intramuscular injection of 1000 of tetanus toxin. The most striking morphological changes, including swelling and rupture of the mitochondria, ...
Adenine nucleotide translocation in liver mitochondria of hypothyroid rats
(Elsevier, 1977-01-30)
In measurements using a disc filtration method, liver mitochondria obtained from hypothyroid rats translocate external ADP at 0 [deg]C via the atractyloside-sensitive carrier much more slowly than do mitochondria from ...
Electron paramagnetic resonance studies on nitrogenase : I. The properties of molybdoferredoxin and azoferredoxin
(Elsevier, 1972-11)
Both molybdoferredoxin and azoferredoxin exhibit EPR signals. Reduced azoferredoxin has a g = 1.94 type signal characteristic of nonheme iron proteins. Reduced molybdoferredoxin has EPR signals with g-values of 2.01, 3.78 ...
Genetic variation in the carbonic anhydrase isozymes of macaque monkeys : III. Biosynthesis of carbonic anhydrases in bone marrow erythroid cells and peripheral blood reticulocytes of Macaco nemestrina
(Elsevier, 1973-09)
The carbonic anhydrase isozymes (CA I and CA II) of the pig-tailed macaque, Macaca nemestrina, have been chosen to study the regulation of enzyme levels in red blood cells. Two quantitative variants of CA I that are ideal ...
Pregnenolone and pregnenolone sulfate metabolism by human fetal testes in vitro
(Elsevier, 1970)
Homogenates of testes from human fetuses of 12-16 weeks gestation were incubated in vitro with pregnenolone-4-14C and pregnenolone-7-3H-sulfate. Dehydroepiandrosterone sulfate and pregnenediol sulfate, each bearing the ...
