A new sialoglycoprotein from rat seminal vesicle and its association with semen coagulum.
Biochem. Biophys. Res. Commun. 136(2) , 753-9, (1986) By radiolabeling using NaIO4/[3H]KBH4, a new sialoglycoprotein with Mr of 19,000 was found in the secretion of rat seminal vesicle. It was shown to interact non-covalently with semen coagulum. It existed in three acidic forms with pI values of 4.1, 3.7 and 2.... |

Synergetic enhancement effect of ionic liquid and diethyldithiocarbamate on the chemical vapor generation of nickel for its atomic fluorescence spectrometric determination in biological samples
Anal. Chim. Acta 652(1-2) , 143-7, (2009) Room-temperature ionic liquid in combination with sodium diethyldithiocarbamate (DDTC) was used to synergetically improve the chemical vapor generation (CVG) of nickel. Volatile species of nickel were effectively generated through reduction of acidified analy... |

Trapping of an intermediate in the reaction catalyzed by 5-oxoprolinase.
J. Biol. Chem. 261(25) , 11538-43, (1986) Bacterial 5-oxoprolinase is composed of two protein components: Component A, which catalyzes 5-oxoproline-dependent ATP-hydrolysis and Component B, which couples the hydrolysis of ATP with the decyclization of 5-oxoproline to form glutamate (Seddon, A. P., Li... |

Inhibition by aminoacyl-chloromethane protease inhibitors of superoxide anion production by phorbol-ester-stimulated human neutrophils. The labeled target is a membrane protein.
Eur. J. Biochem. 193(2) , 345-50, (1990) In a previous paper, we described the kinetic characteristics of the inhibition exerted by the protease inhibitors tosylphenylalanyl and tosyllysyl chloromethanes on superoxide production by human polymorphonuclear leukocytes when stimulated by phorbol esters... |
