NAD+-Dependent 15-Hydroxyprostaglandin Dehydrogenase from Swine Kidney: Characterization and Kinetic Mechanism

Description: Cytoplasmic 15-hydroxyprostaglandin dehydrogenase from swine kidney was purified to specific activity of 1.2 U per mg protein, by chromatographic techniques. Native molecular weight of enzyme was estimated at 45,000. Enzyme was inhibited by sulfhydryls, diuretics, and various fatty acids. Substrate studies indicated NAD+ specificity and ability to catabolize prostaglandins, except prostaglandin B and thromboxane B. Initial velocity studies gave intersecting plots conforming to a sequential mec… more

A Rapid, Accurate Thin Layer Chromatographic Analysis of Phospholipids and Neutral Lipids

Description: A modified ascending thin layer chromatographic technique has been developed which resolves the major phospholipid and neutral lipid classes of five common fluids and tissues. A one-half milliliter sample is extracted with n-butanol:diisopropylether (40:60 by volume, cholesteryl acetate = 100 ng/ul) for thirty minutes and the organic phase is spotted onto a thin layer chromatography plate and carried through three successive chromatographic developments. The lipids are then visualized either by… more
