1. Padroes isoenzimaticos de trialeurodes vaporariorum e bemisia tabaci (Homoptera, Aleyrodidae) e de Encarsia formosa e E. lycopersici (Hymenoptera, Aphelinidae).
Os danos causados a economia agricola pelas moscas-brancas tem aumentado significativamente nas mais diferentes regioes geograficas. A analise eletroforetica de isoenzimas de Alfa e Beta esterase foi utilizada como um marcador molecular, para o reconhecimento das variacoes geneticas entre os individuos das especies de moscas-brancas, Trialeurodes vaporarioru

2. Caracterização da DNase da peçonha da serpente Bothrops alternatus : comparação com a DNase acida de mamiferos envolvida em apoptose / Characterization of a Dnase from Bothrops alternatus snake venom : comparision with mamalian acid Dnases involved in apoptosis
Bothrops snake venoms are cytotoxic to a variety of cells (endothelial, smooth muscle, renal and inflammatory cells), and may cause cell death by apoptosis. The venom components implicated in apoptosis include metalloproteinases and L-amino acid oxidase. In contrast, although acidic deoxyribonucleases (DNase II) have been implicated in DNA fragmentation duri

4. The partial amino-acid sequence of an H-2K molecule.
Eighteen of the NH2-terminal 27 amino acids of a murine H-2K molecule have been assigned. The approach used was to label murine splenocytes with a single radioactive amino acid, isolate the H-2K molecule by specific immunoprecipitation, electrophorese the dissolved precipitate on sodium dodecyl sulfate polyacrylamide gels, and subject the isolated H-2K peak

5. Occurrence of nickel in carbon monoxide dehydrogenase from Clostridium pasteurianum and Clostridium thermoaceticum.
The carbon monoxide (CO) dehydrogenase activity band from Clostridium pasteurianum was shown to contain nickel by in situ activity staining of polyacrylamide gels. However, the majority of the nickel in cell extracts was found to electrophorese independently of CO dehydrogenase. Comparative analysis with Clostridium thermoaceticum demonstrated that, although

6. Virus-Induced Proteins in Pseudorabies-Infected Cells I. Acid-Extractable Proteins of the Nucleus
Three basic proteins have been identified in chromatin preparations from pseudorabies virus-infected cells. They appear to be virus specified and are similar in size and charge to host histones; one difference however is that they contain tryptophan. All are produced by 3 h postinfection, and two (IP II and III) seem to be arginine rich. Three similar protei

7. Chromatin subunits from baker's yeast: isolation and partial characterization.
The organization of proteins along DNA in chromatin of Saccharomyces cerevisiae (baker's yeast) was examined by analyzing the DNA and nucleoprotein products obtained after digestion of yeast nuclei with staphylococcal nuclease. Yeast DNA is digested in situ at regularly spaced cleavage sites about 160 base pairs apart. Nucleoprotein fragments were resolved a

8. Comparative Immunochemistry of Phytochrome
Partially purified high molecular weight preparations of phytochrome, estimated to be close to 440,000 molecular weight based upon chromatography through a calibrated Bio-Gel P-300 column, were obtained from Garry and Newton oats (Avena Sativa L., cv. Garry and cv. Newton), rye (Secale cereale L., cv. Balbo), barley (Horedum vulgare L., cv. Harrison), and pe
