Tumor cell-derived exosomes are considered a potential source of cancer biomarkers. Here, we developed an electrochemical sensing platform for the rapid and simple detection exosomes, using CCRF-CEM exosome as model. The utilizes cyclic nicking enzyme cleavage hybridization chain reaction (HCR) dual-signal amplification. A hairpin aptamer probe (HAP) containing was designed assay. specific bind...
The genomic in situ hybridization (GISH) has been used to identify euploidy and aneuploidy in segregation generations of various plants. In this study, the GISH with minor modifications including, slide preparation of putative secondary Tritipyrum (F2) root meristemic cells, labeled genomic DNA of Thinopyrum bessarabicum by fluorescein 12-dUTP nucleotide as probe, genomic DNA of Thinopyrum bess...

Twenty to thirty percent of causative agents of the respiratory tract infections are still unknown, that can be related to the lack of suitable laboratory procedures. Some of these organisms may cause progressive infection such as encephalitis and cardiac complications. To recognize the M. pneumoniae , PCR-hybridization technique was used and a specific internal probe was produced for this...
background hepatitis b virus (hbv) covalently closed circular dna (cccdna) served as a vital role in the life cycle of the virus and persistent infection. however, specific and quantitative methods for cccdna detection have not been available. objectives our aim was to develop and primarily evaluate a quantitative method for hbv cccdna based on magnetic capture hybridization and quantitative pc...
objective: electroporation is the most common method used for the transfection of dna. although this method has been attributed for various cell using different buffer compositions, the effects of dna concentration on the transfection efficiency has not yet been studied. here the correlation between the efficiency of electroporation reaction and increments of dna concentration has been investig...
Background and Objective: Epidemiological studies indicate that not only the incidence of fungal infections is dramatically on the rise, especially in the immunocompromised hosts, but also the sensitivity of etiological agents to antifungal drugs shows a remarkable reduction. Therefore, early detection at the species level is critically important for proper clinical management. Because standard...
