We have used restriction endonucleases PstI, EcoRI, HapII, HhaI, and S1 nuclease to demonstrate the presence of a large complex component, the maxi-circle, in addition to the major mini-circle component in kinetoplast DNA (kDNA) networks of Trypanosoma brucei (East African Trypanosomiasis Research Organization [EATRO] 427). Endonuclease PstI and S1 nuclease cut the maxi-circle at a single site,...
A Nicaraguan field isolate (SfNIC) of Spodoptera frugiperda nucleopolyhedrovirus was purified by plaque assay on Sf9 cells. Nine distinct genotypes, A to I, were identified by their restriction endonuclease profiles. Variant SfNIC-B was selected as the standard because its restriction profile corresponded to that of the wild-type isolate. Physical maps were generated for each of the variants. T...
Polymorphisms. PstI, HindIII, and TuqI restriction fragment length polymorphisms (RFLP) in the bovine Uroplukin IB (UPKlB) gene. Source and Description ofProbe. The UPKlB probe is a .5-kb PCR product encoding a 27-kDa bovine Uroplukin IB protein associated with the urothelial asymmetric unit membrane (Yu et al., 1994). The insert was radiolabeled with [ c Y ~ ~ P I ~ C T P to a specific activit...
BACKGROUND In 2010, a universal nomenclature for varicella-zoster virus (VZV) clades was established, which is very useful in the monitoring of viral evolution, recombination, spread and genetic diversity. Currently, information about VZV clades has been disclosed worldwide, however, there are limited data regarding the characterization of circulating VZV clades in China, even where varicella r...
Published data on any association between the CYP2E1 RsaI/PstI (c1/c2) polymorphism and liver cancer risk among east Asians are inconclusive. The aim of this Human Genome Epidemiology (HuGE) review and meta- analysis was to derive a more precise estimation of the relationship. A literature search of Pubmed, Embase, Web of science and CBM databases from inception through July 2012 was conducted....
A plasmid library of PstI fragments of Haemophilus influenzae Rd genomic DNA was mutagenized in Escherichia coli with mini-Tn10kan. The mutagenized PstI fragments were introduced by transformation into the H. influenzae chromosome, and kanamycin-resistant transformants were screened for the transformation-deficient phenotype by a cyclic AMP-DNA plate method. Fifty-four mutant strains containing...
CYP2E1 PstI polymorphism G-1259C (rs3813867) genotype distributions vary significantly among different populations and are associated with both diseases, like cancer, and adverse drug effects. To date, there have been limited genotype distributions and allele frequencies of this polymorphism reported in the three major indigenous ethnic groups (KadazanDusun, Bajau, and Rungus) in Sabah, also kn...
