(1988)Cell-free extracts of Thermus thermophilus HB8 catalyze the in vitro, NADH-dependent reduction of potassium tellurite (K2TeO3). Three different protein fractions with tellurite-reducing activities were identified. Two ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1992-11)Two isoenzymes of ATP-diphosphohydrolase (apyrase) were extracted and purified from S. tuberosum var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were 1.0 (apyrase B) and ca 15.0 (apyrase A). They were ...
-
(BioMed Central, 2017)Background: Amylases are used in various industrial processes and a key requirement for the efficiency of these processes is the use of enzymes with high catalytic activity at ambient temperature. Unfortunately, most ...
-
(1995)A DNA polymerase was purified to near homogeneity from Trypanosoma cruzi epimastigotes. This preparation had a major polypeptide of 50 kDa and a minor band of 45 kDa. SDS-PAGE studies and a novel colorimetric activity gel ...
-
(1982)Mevalonate-5-pyrophosphate decarboxylase [ATP:5-diphosphomevalonate car boxy-lyase (dehydrating), EC 4.1.1.33] has been purified 5800 times from chicken liver and obtained in a stable and highly purified form. The protein ...
-
(Kluwer Academic Publishers, 1988)A liver cytochrome P-450 isozyme has been purified to homogeneity from protein-energy malnourished rats induced with β-naphthoflavone (β-NF). The purification steps included chromatography on DEAE-Sephadex-A-25, DEAE-cellulose ...
-
(Kluwer Academic Publishers, 1994)The changes in the levels of microtubule-associated proteins (MAPs) during advanced embryonic stages, neonatal and adult organisms reflect the importance of these cytoskeletal proteins in relation to the morphogenesis of ...

(1992)Two isoenzymes of ATP-diphosphohydrolase (apyrase) were extracted and purified from S. tuberosum var. Ultimus. Their hydrolytic activity ratios (ATPase/ADPase) were 1.0 (apyrase B) and ca 15.0 (apyrase A). They were ...
-
(American Society of Tropical Medicine and Hygiene, 1995)In spite of being separated by more than 20 million years of evolution, the murine and human immune systems share extensive similarities. Thus, experimental results obtained with the murine model may have predictive value ...
-
(Wiley, 2017)BACKGROUND: Gene therapy is a potent alternative for long-lasting inhibition of alcohol consumption. This study compares the purification of a recombinant adenoviral vector serotype 5 (rAdV5) for use in gene therapy against ...
-
(Elsevier, 2017)Phlorotannins are secondary metabolites produced by brown seaweed, which are known for their nutraceutical and pharmacological properties. The aim of this work was to determine the type of macroporous resin and the ...
