Characterization of a mutant human erythrocyte carbonic anhydrase: Carbonic anhydrase IcGuam: The amino acid substitution and carboxylesterase and hydratase activities
(Elsevier, 1966-11)
Evidence is presented which indicates that an arginine residue has substituted for a glycine residue in the abnormal human erythrocyte carbonic anhydrase, CA IcGuam. The ratio of the amount of mutant to normal enzyme ...
Physicochemical and immunochemical studies on the reaction of bovine serum albumin with p,p'-difluoro-m,m'-dinitrodiphenylsulfone
(Elsevier, 1963-02)
Bovine serum albumin (BSA) was reacted with the bifunctional reagent p,p'-difluoro-m,m'-dinitrodiphenylsulfone (FNPS) under varying conditions. While intramolecular cross linkages involving the lysine and tyrosine residues ...
Mixing device for generating simple chromatographic gradients
(Elsevier, 1965-10)
A linear gradient device consisting of two concentric reservoirs of equal cross-sectional area, in which the initial and limiting eluent solutions are maintained in hydrostatic equilibrium, may be constructed from several ...
A quantitative automated technique for the determination of diazotizable imidazole compounds in biological material
(Elsevier, 1966)
A quantitative automated apparatus is described for the simultaneous determination of a number of diazotizable imidazole compounds in the same sample of biological material. Its use in the analysis of urine, plasma and ...
The ATP-ADP exchange catalyzed by phosphoryl transferase
(Elsevier, 1968)
Purified phosphoryl transferase catalyzes an ATP-ADP exchange reaction. Evidence is presented which excludes the possibility that the exchange activity of the preparation is due to contaminating adenylate kinase. The rate ...
A comparison of the properties of two forms of tyrosinase from Neurospora crassa
(Elsevier, 1961-12)
The differences between a thermostable (T) and thermolabile (T) form of tyrosmase from Neurospora crassa have been studied by means of a spectrophotometric technique using ascorbate or ferrocyanide. No significant differences ...
The photometric estimation of luciferase in luminous bacterial cells
(Elsevier, 1963-05)
The bacterial luciferase reaction carried out in vitro can be used as a basis for a semiquantitative assay of active luciferase in bacterial cells. Relations between maximum luminous intensity generated and the amount of ...
Estimation of free methylpentoses in the presence of glycosidically bound sugar
(Elsevier, 1966-02)
1. (1) A very sensitive method has been presented for the determination of 0.01-0.5 [mu]moles of methylpentose.2. (2) Many compounds which give rise to acetaldehyde on oxidation with periodate can be determined by this ...
