Los colorantes FM son compuestos de estiril lipofílico utilizados en una amplia variedad de estudios que involucran membrana plasmática y vesiculación. Los colorantes solubles en agua FM® son prácticamente no fluorescentes en medios acuosos y se cree que se insertan en la membrana de la superficie donde se vuelven intensamente fluorescentes. La tinción FM® 1-43 se ha utilizado con éxito para teñir los cuerpos celulares específicamente en una biopelícula compleja mileu, incluyendo Pseudomonas aeruginosa, Escherichia coli, Staphylococcus sp., Acidothiobacillus caldus y Vibrio cholerae.
Para uso exclusivo en investigación. No apto para uso en procedimientos diagnósticos.

Preguntas frecuentes
The product sheet for FM 1-43 Dye states that the maximum for excitation is 510 nm and emissions is 626 nm, but the spectrum on the product page shows a peak at 470 nm and 580 nm. Can you clarify what the excitation and emission maxima is for this dye?
FM lipophilic styryl dyes are known to shift their spectral properties upon binding to membranes. These dyes exhibit an appreciable solvent and environmental dependency in both free and membrane-bound forms. The emissions of the membrane-bound dye shifts to a shorter wavelength compared to the emission in the solvent.
In solvent, FM 1-43 Dye (Cat. Nos. T35356, T3163, F35355, F10317) absorbs in the range of fluorescein (~490 nm) and initially emits at around 626-636 nm. However, upon membrane integration, it exhibits emission in the 565-590 nm range. Because this dye exhibits a large Stokes shift, it does not perfectly fit into a green or orange fluorophore profile, but is rather a yellow-fluorescent dye, and may require a long-pass emission filter.
Note: FM 1-43 Dye is often used with typical fluorescein or GFP optical filter sets for biological imaging but is poorly excited through tetramethylrhodamine filters.
A novel role for enzyme I of the Vibrio cholerae phosphoenolpyruvate phosphotransferase system in regulation of growth in a biofilm.

Glucose is a universal energy source and a potent inducer of surface colonization for many microbial species. Highly efficient sugar assimilation pathways ensure successful competition for this preferred carbon source. One such pathway is the phosphoenolpyruvate phosphotransferase system (PTS), a multicomponent sugar transport system that phosphorylates the sugar as it ... More
Fluorescence staining of live cyanobacterial cells suggest non-stringent chromosome segregation and absence of a connection between cytoplasmic and thylakoid membranes.

PubMed ID:17767716
BACKGROUND: In spite of their abundance and importance, little is known about cyanobacterial cell biology and their cell cycle. During each cell cycle, chromosomes must be separated into future daughter cells, i.e. into both cell halves, which in many bacteria is achieved by an active machinery that operates during DNA ...
