Rapid protein release from Escherichia coli by chemical permeabilization under fermentation conditions
(Wiley Subscription Services, Inc., A Wiley Company, 1992-03-25)
Overall protein release greater than 75% in less than 1 h can be attained by exposing exponentially growing Escherichia coli cells to 0.4 M guanidine plus 0.5% Triton X-100 at 37°C in medium. Cell growth stops immediately ...
Effect of Coadsorbed Water on Deep Oxidation Mechanisms: Temperature-Programmed Reactions of Benzene and Hydroxyl on the Pt(111) Surface
(Kluwer Academic Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2004-03)
The deep oxidation of benzene by preadsorbed hydroxyl on the Pt(111) surface has been characterized using temperature-programmed reaction spectroscopy. A mechanism for benzene oxidation in the presence of coadsorbed water ...
Virulent mutants of phage P22 : II. Physiological analysis of P22 virB-3 and its component mutations
(Elsevier, 1972-03)
The virulent mutant of phage P22, virB-3, consists of two mutations: K5, which maps in the c2 repressor gene, and Vx, which maps between c2 and c3. Although neither P22 K5 nor P22 Vx is virulent, each of these mutants can ...
Properties of yeast pyruvate decarboxylase and their modification by proteolytic enzymes : I. Stability of decarboxylases from wild-type and mutant strains
(Elsevier, 1968)
High concentrations of inorganic phosphate and ammonium sulfate stabilize yeast pyruvate decarboxylase to heating at 60 [deg] for long periods of time in the presence of TPP and Mg+. When heated at 60 [deg] in phosphate ...
MoFe Cofactor of nitrogenase: Extraction, purification, and characterization
(Elsevier, 1989-08)
Macrophage infiltration in human non-small-cell lung cancer: the role of CC chemokines
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-04)
Bronchogenic carcinoma is the leading cause of malignancy-related mortality in the United States, with an overall 5-year survival rate of less than 15%. This aggressive behavior reflects, among other traits, the capacity ...
Ototoxicity of aminoglycosides correlated with their action on monomolecular films of polyphosphoinositides
(Elsevier, 1980-02-15)
The ototoxicities of eight aminoglycoside antibiotics and fragments were measured quantitatively by cochlear perfusion in the guinea pig. Perilymphatic spaces were perfused for 1 hr with `artificial perilymph' containing ...
