The direct F.A. Method has been used for differentiation of virulent and avirulent lines of influenza viruses. A positive fluorescence was obtained indicating the level of virus in the tissues, sorbing with dried mouse powder helped to reduce non-specific staining. The virulent line showed the greatest number of fluorescent cells with the peak at 10 hours. the non-virulent lines showed a gra...
abstract the role of fluorescent pseudomonads in biocontrol of take-all disease caused by gaeumannomyces graminis var.tritici (ggt) has been the subject of many researchs in the recent years. biofilm formation in fluorescent pseudomonads play an important role in biocontrol disease. for this purpose,130 strains of fluorescent pseudomonads isolated from wheat rhizosphere in different regions of ...
abstract background: determination of transgenic embryos from non transgenic embryos sibling is an important step in producing homozygous transgenic mice. these steps need by pcr or southern blotting followed extraction of dna, but both techniques require skill and consume time. objective: the aim of this study was simulation of high accuracy method using novel enhanced green fluorescent protei...
Background and purpose: Salmonella is a group of Enterobacterias that cause infectious diseases in human and animals. Typhoid, bacteremia, enterocolitis and salmonellosis which are caused by this bacterium are considered major health concerns in developing countries, such as Iran. Quick, accurate, reliable and early diagnosis is vital to prevent Salmonella outbreak. Materials and methods: Ther...
Introduction: In recent years, use of compact fluorescent lamps has increased in order to optimize energy consumption. The aim of this study was to evaluate the radiations of electromagnetic spectrum from usual compact fluorescent lamps. Methods: In this study, 48 compact fluorescent lamps from different brands and cover (warm – cool) were selected. For studied lamps, operational facto...
This highlight review overviews recent progress in fluorescence imaging technology for the alkaline-earth metal ions calcium, and magnesium, by small molecule-based fluorescent probes. Fluorescent ...
P-11: DHR123: A Suitable Fluorescent Mitochondrial Probe for Assessment of H2O2 in Human Spermatozoa
Background: The objective of present study was to assess potential of DHR123 (dihydrorhodamine 123) fluorescent probe for measurement of H2O2 produced by human spermatozoa and comparing the results with DCFH-DA (2', 7'-dichlorodihydrofluorescein diacetate). Materials and Methods: Fluorescent intensity and percentage R123 and DCF positive sperm measured by flow cytometry. The suitable ...
The non-fluorescent 9-nitrobenzo[ b ]quinolizinium is readily reduced by nitroreductase to fluorescent reaction products whose formation depends on the conditions.
We developed a unique self-labeling protein based on the small Ultra-Red Fluorescent Protein and named smURFP-tag. Biliverdin is fluorogenic, fluoresces when covalently attached, quenches fluorescent cargo.
Background: Baculovirus expression system is one of the most attractive and powerful eukaryotic expression systems for the production of recombinant proteins. The presence of a biomarker is required to monitor transfection efficiency or protein expression levels in insect cells. Methods: The aim of this study was to construct a baculovirus expression vector encoding a copepod super green fluore...
