Quantitative variations in the expression of the mouse serum antigen Ss and its sex-limited allotype Slp
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-10)
A radial immunodiffusion assay for quantitation of the Ss and Slp serum antigens is described. Significant differences between the mean serum concentrations of Ss and Slp were found among various inbred strains. Some of ...
Nucleotide sequence divergence among DNA fractions of different syngens of Tetrahymena pyriformis
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1974-09)
The magnitude of the differences in base sequence of DNA fractions derived from different syngens of the ciliated protozoan Tetrahymena pyriformis was investigated. Each DNA was fractionated into unique and repeated sequences ...
Observations on chytridiaceous parasites of phanerogams
(Springer-Verlag, 1974-01)
The morphology and reproduction of a Physoderma found on Ranunculus septentrionalis Poir. in Northern Michigan are described. Host range studies indicate it is confined to certain Ranunculaceae and does not infect hosts ...
Highly purified detergent-solubilized NADPH-cytochrome P-450 reductase from phenobarbital-induced rat liver microsomes
(Elsevier, 1974-10-23)
NADPH-cytochrome P-450 reductase was highly purified from liver microsomes of phenobarbital-induced rats by column chromatography on DEAE-cellulose, DEAE-Sephadex A-50, and hydroxylapatite in the presence of deoxycholate ...
Identification of the [omega]-hydroxylase of Pseudomonas oleovorans as a nonheme iron protein requiring phospholipid for catalytic activity
(Elsevier, 1974-04-23)
Fatty acid and alkane hydroxylation by the inducible, cyanide-sensitive enzyme system of Pseudomonas oleovorans involves three enzymes: NADH-rubredoxin reductase, rubredoxin, and an [omega]-hydroxylase. The [omega]-hydroxylase ...
Horizontal compensatory eye movements in goldfish ( Carassius auratus )
(Springer-Verlag, 1974-03)
1. Goldfish were deprived of visual input and/or normally functional horizontal semicircular canals.
Hyperproduction of some glycosidases in Neurospora crassa
(Springer-Verlag, 1974-01)
Results of a cross between a hyperderepressed strain (89601 a) and a normal strain (74A) of Neurospora crassa suggest that there is a single gene difference in this trait. The evidence is clearest with amylase although a ...
Cytochrome P-450 purified to apparent homogeneity from phenobarbital-induced rabbit liver microsomes: Catalytic activity and other properties
(Elsevier, 1974-09-23)
Cytochrome P-450 was purified to a content of over 17 nmoles per mg of protein from liver microsomes of phenobarbital-treated rabbits by fractionation with polyethylene glycol 6000, DEAE-cellulose column chromatography, ...
Intermediates in flavoprotein catalyzed hydroxylations
(Elsevier, 1974-04-23)
The reaction of molecular oxygen with the complex of reduced p-hydroxybenzoate hydroxylase and 2,4-dihydroxybenzoate has been followed by rapid reaction techniques. During the reaction, which produces stoichiometric amounts ...
