A novel cloning strategy, replicon rescue, was developed for cloning genes disrupted by plasmid insertions. After ligation to a tetracycline resistance cassette, fragments containing a bacterial origin of replication from the insertion are recovered in Escherichia coli because they replicate autonomously. Restriction enzymes for cloning are so chosen that the only legitimate two fragment ligati...

The etiology of osteoarthritis (OA) is complex and multifaceted. Osteoarthritis is a chronic and progressive disease of the joints that is characterized by the degradation of articular cartilage. A disintegrin and metalloproteinase with thrombospondin motifs-5 (ADAMTS-5) is the major aggrecanase in cartilage. The aim of this study was to evaluate the effect of ADAMTS-5 knockdown on cartilage de...

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...

The claR of Streptomyces clavuligerus in the clavulanic acid gene cluster encodes a transcriptional regulator that controls clavulanic acid biosynthesis. The main goal of this study was isolation and molecular detection of the claR gene and its cloning in the Streptomyces specific vector (pMA:: hyg). By cinsideration of the claR gene’s start codon, the specific primers were designed. After geno...

Vol. 40, No. 4 (2006) BioTechniques 1 Supplementary Figure S1. Structure of constructs used and representation of FRT locus. (A) Plasmids used to detect the Bxb1 integrase-mediated sitespecific recombination. CMVp, SV40t, Luc, stop, and Hygro are cytomegalovirus promoter (CMVp), simian virus 40 terminator (SV40t), luciferase gene, transcription termination sequence, and hygromycin resistance ge...

Isolating and cloning of plant protease inhibitor (PIs) genes and transforming them to the genome of other plants have paved the way for producing resistant transgenic plants against pests. Knowing that cystatins act as inhibitor factor against cysteine protease, short and long cystatin genes were isolated from maize mRNA. By using specific primers, cDNA of these genes were constructed and clon...

in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...

We report the molecular cloning of the tomato golden mosaic virus (TGMV) genome in the E. coli plasmid pAT 153. The results of this work conclusively show that TGMV DNA consists of two components (designated A and B) of almost, but not exactly, the same size. Four different recombinant plasmids are described, two containing component A in opposite orientation and two containing component B in o...

We report herein the synthesis and biological testing of several glycosylated derivatives of some fluoroquinolone antibiotics. In particular, we have prepared several glycosylated derivatives of ciprofloxacin (2) in which the carbohydrate units are linked to the free secondary amine of the piperazine unit by: (a) no linker (e.g., a glycosylamine), (b) a beta-oxyethyl linker, and (c) a gamma-oxy...
