Structure of hepatitis B Dane particle DNA and nature of the endogenous DNA polymerase reaction.
The circular DNA of hepatitis B Dane particles, which serves as the primer/template for an endogenous DNA polymerase, was analyzed by electrophoresis before and after a polymerase reaction and after digestion by restriction endonuclease or single-strand-specific endonuclease S1. The unreacted molecules extracted from the particles were electrophoretically heterogeneous, and treatment with S1 nu...
متن کاملDNA synthesized in the hepatitis B Dane particle DNA polymerase reaction.
Radioactive DNA was prepared in extensive (4 h) Dane particle DNA polymerase reactions. In different experiments the amount of new DNA, determined by the amount of nucleotide incorporation into an acid-insoluble form, was between 29 and 45% of the total circular DNA isolated from Dane particle preparations after the reaction. DNA reassociation kinetics were used to determine the complexity of t...
متن کاملGenome of hepatitis B virus: restriction enzyme cleavage and structure of DNA extracted from Dane particles.
DNA extracted from Dane particles has been characterized by gel electrophoresis and restriction enzyme cleavage with endonuclease R-HaeIII (from Hemophilus aegyptius). Dane particle DNA is proposed to be a double-stranded circular DNA approximately 3600 nucleotides in length containing a single-stranded gap of 600-2100 nucleotides. The endogenous DNA polymerase (DNA nucleotidyl-transferase; deo...
متن کاملRelease of e antigen from a Dane particle-rich preparation of hepatitis B virus.
Tween 80 treatment of a Dana particle-rich pellet obtained from sera of a carrier with a hepatitis type B infection resulted in the release of e antigen.
متن کاملSPECIFIC AMPLIFICATION OF ASPERGILLUS FUMlGATUS DNA BY POLYMERASE CHAIN REACTION
Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...
