Trypanosoma Equiperdum

Kinetoplast DNA, the mitochondrial DNA in trypanosomes, is a giant network containing topologically interlocked minicircles. Replication occurs on free minicircles that have been detached from the network. In this paper, we report studies on the synthesis and processing of the minicircle L and H strands. Analysis of free minicircles from Trypanosoma equiperdum by two-dimensional agarose gel electrophoresis indicated that elongating L strands are present on theta structures. Hybridization studies indicated that L-strand elongation is continuous and unidirectional, starting near nucleotide 805 and proceeding around the entire minicircle. The theta structures segregate into monomeric progeny minicircles, and those with a newly synthesized L strand have a 8-nucleotide gap between nucleotides 805 and 814 (J. M. Ntambi, T. A. Shapiro, K. A. Ryan, and P. T. Englund, J. Biol. Chem. 261:11890-11895, 1986). These molecules are reattached to the network, where repair of the gap takes place. Of the molecules labeled during a 10-min pulse with [3H]thymidine, gap filling occurred on half within about 15 min and on virtually all by 60 min; however, there was no detectable covalent closure of the newly synthesized L strand by 60 min.

Lipoprotein Pattern

Abstract A previously reported agarose gel electrophoretic technique for the determination of serum lipoprotein patterns has been modified for analysis of a large number of samples for screening and epidemiological purposes. In addition, we demonstrate the varieties of lipoprotein patterns that can clearly be distinguished and visually evaluated for practical applications in the clinical laboratory.

Two components of pig mucosal heparin were separated by agarose-gel electrophoresis and recovered from the gels. The slower moving component had the higher anticoagulant activity and intrinsic viscosity. The faster moving component had the higher sulfate : carboxyl ratio. Each component was degraded by self-hydrolysis to N-desulfated heparin, deaminated with nitrous acid, and hydrolyzed with formic acid. Two-dimensional electrophoresis and chromatography on thin layers of cellulose showed that each component had two uronic acids with the characteristics of glucuronic and iduronic acids.
