Identification of differentiating muscle cells generally requires fixation, antibodies directed against muscle specific proteins, and lengthy staining processes or, alternatively, transfection of muscle specific reporter genes driving GFP expression. In this study, we examined the possibility of using the robust mitochondrial network seen in maturing muscle cells as a marker of cellular differe...

In this study, a microcolony technique was combined with direct fluorescent antibody staining for the specific detection and enumeration of Legionella pneumophila in freshwater samples with growth activity. This method allowed the detection of active L. pneumophila (within 48 h) in 91 bath water samples collected from 30 bathing facilities, with similar sensitivity of a conventional plate-count...

Circulating tumor cells (CTCs) are routinely identified as cytokeratin (CK)-positive, epithelial cell adhesion molecule (EpCAM)-positive, and CD45-negative and are enriched based on EpCAM. However, there are a number of methodological challenges regarding both isolation and characterization of these rare CTCs including downregulation or absence of EpCAM in a variety of solid tumors leading to t...

BACKGROUND Tuberculosis (TB) is an increasing public health concern worldwide. On a global scale it has a devastating impact in developing nations. Genital TB, an extrapulmonary form, is not uncommon particularly in areas where pulmonary TB is prevalent. Genital TB may be asymptomatic or may even masquerade as other gynaecological conditions; hence, diagnosis requires a high degree of suspicion...

Abstract Development of latent prints employing cyanoacrylate ester (CA) can be a multistep process including CA fuming and subsequent fluorescent staining to produce fingerprints sufficient contrast for comparison work. To enable single‐step fuming—staining process, selection fluorophores have been developed as sublimation dyes in fuming. A greater array such luminescent would allow users flex...

We have investigated the use of fluorescence detection and the FluorImager S1 System (Molecular Dynamics) for analyzing a comprehensive set of human DNA typing tests. We used an alkaline phosphatase-conjugated YNH24 oligonucleotide probe to the repeat-containing D2S44 locus to detect both alleles in 50 ng of human genomic DNA (0.025 amol) by Southern hybridization using a chemifluorescent subst...

Objective: Tuberculosis (TB) one of the most important major causes of mortality and morbidity around the world. Early detection of TB affords to prevent transmission of TB and better treatment options. The aim of this study is to evaluate sensitivity of fluorescent, Ziehl Neelsen microscopy and Polymerase Chain Reaction (PCR) method. Methods: Fifty samples of clinically suspected cases of pulm...

Great efforts have been made to develop fluorescent probes for pyrophosphate (PPi) detection. Nucleus staining with fluorescence microscopy has been also widely investigated. But fluorescent probes for PPi detection with high sensitivity in water medium and nucleus staining with low-cost non-precious metal complexes in living cells are still challenging. Herein, we report simple terpyridine-Zn(...

X-34, a lipophilic, highly fluorescent derivative of Congo red, was examined as a histochemical stain for pathological changes in Alzheimer's disease (AD). X-34 intensely stained neuritic and diffuse plaques, neurofibrillary tangles (NFTs), neuropil threads, and cerebrovascular amyloid. Comparison to standard methods of demonstrating AD pathology showed that X-34 correlated well with Bielschows...
