Properties of a partially-purified preparation of the prostaglandin-forming oxygenase from sheep vesicular gland
(Elsevier, 1975-11)
The fatty acid oxygenase of sheep vesicular glands was solubilized with Tween-40 and purified 60-fold using ammonium sulfate precipitation and DEAE-cellulose chromatography. Glycerol (50%) stabilized the activity at all ...
Hydrogen ion buffers and enzymatic activity: Myosin B adenosinetriphosphatase
(Elsevier, 1968-10)
The production of hydrogen ions during the hydrolysis of ATP by myosin B and the consequent fall in pH can produce alterations in enzymatic activity directly, or by influencing Ca ion concentrations controlled by metal-chelate ...
Selective effect of alcohol on cellular immune responses of lymphocytes from AIDS patients
(Elsevier, 1994)
In this study we examined the in vitro effects of alcohol on the proliferative responses of lymphocytes from healthy donors and AIDS patients to a recombinant fusion peptide, env-gag, corresponding to portions of the gp ...
Protection of 2′‐Hydroxy Functions of Ribonucleosides
(Oxford University PressWiley Periodicals, Inc., 2000-02)
The main purpose of this article is to discuss 2′‐protection in the context of effective oligoribonucleotide synthesis. Emphasis is placed on the 2′‐protecting groups of choice in the synthesis of oligo‐and polyribonucleotides, ...
Influence of bovine diabetogenic peptide, growth hormone, and prolactin on tissue glycogen, liver fat, and liver water of fasting rats
(Elsevier, 1971-06)
1. 1. Bovine diabetogenic peptide, growth hormone, and prolactin were compared with respect to their effects on tissue glycogen, liver fat, and liver water in fasting rats.2. 2. Bovine diabetogenic peptide increases liver ...
Purification of the catalytically active phosphorylated form of insulin receptor kinase by affinity chromatography with O-phosphotyrosyl-binding antibodies
(Elsevier, 1985-10)
The catalytically active, tyrosyl-phosphorylated form of insulin receptor kinase was isolated from human placenta by a procedure which exploits the propensity for the intact [alpha]2[beta]2 form of insulin receptor to ...
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 ...
