Although increasingly used for DNA quanti®cation, little is known of the dynamics of the 5¢ exonuclease assay, particularly in relation to amplicon length and mismatches at oligonucleotide binding sites. In this study we used seven assays targeting the c-myc proto-oncogene to examine the effects of sequence length, and report a marked reduction in ef®ciency with increasing fragment length. Thre...
it has been investigated the in vitro antioxidant properties of ethanol extracts of the contained-allantoin plants in this study. contained-allantoined plant samples plantago lanceolata, plantago major, robinia pseudoacacia, platanus orientalis and aesculus hippocastanum were tested at different concentrations. the antioxidant activities of plant samples were analysed by 1,1- diphenyl-2-picrylh...
Cell adhesion in the presence of hydrodynamic forces is a critical factor in inflammation, cancer metastasis, and blood clotting. A number of assays have recently been developed to apply forces to small numbers of the receptor–ligand bonds responsible for adhesion. Examples include assays using hydrodynamic shear in flow chambers or elastic probe deflection assays such as the atomic force micro...
BACKGROUND Diagnosing drug-resistance remains an obstacle to the elimination of tuberculosis. Phenotypic drug-susceptibility testing is slow and expensive, and commercial genotypic assays screen only common resistance-determining mutations. We used whole-genome sequencing to characterise common and rare mutations predicting drug resistance, or consistency with susceptibility, for all first-line...
A total of 201 endocervical specimens were obtained from patients with a clinical or epidemiological history suggestive of chlamydial infection. These specimens were tested by DNA probe (Gen-Probe, San Diego, Calif.) and the IDEIA III (Boots-Celltech, Berkshire, United Kingdom) monoclonal antibody enzyme immunoassay and compared with cell culture for detection of Chlamydia trachomatis. Discrepa...
Hydrolysis of fluorescent GTP analogues BODIPY FL guanosine 5 '-O-(thiotriphosphate) (BGTPgammaS) and BODIPY FL GTP (BGTP) by Galpha(i1) and Galpha was characterized using on-line capillary electrophoresis (o) laser-induced fluorescence assays in order that changes in sub-strate, substrate-enzyme complex, and product could be monitored separately. Apparent k values (V /[E]) (max cat) steady-sta...
The induction of tetraploidy by means of cold, heat and multiple heat shock treatments was investigated on male fish from a growth-enhanced transgenic tilapia C118 line, crossed with wild type females. After the development a new multiple heat shock protocol (two heat treatments at 41oC in 60 and 80 min. after fertilization for 5 min. per each), chromosome and X-gal in situ staining assays demo...
