We present a method to isolate rapid (microsecond) calcium events from slower fluxes in living cells using laser scanning confocal microscopy. The method measures fluorescence intensity fluctuations of calcium indicators by recording line scans of several hundred pixels in a cell. Histogram analysis allows us to isolate the time scales of different calcium fluxes.

The preparation and exfoliation of CaCuSi4O10 and BaCuSi4O10 are described. Upon stirring in hot water, CaCuSi4O10 spontaneously exfoliates into monolayers, whereas BaCuSi4O10 requires ultrasonication in organic solvents. Near infrared (NIR) imaging illustrates the NIR emission properties of these materials, and aqueous dispersions of these nanomaterials are useful for solution processing.

Fast reactions occurring in times shorter than the time needed to mix reactants pose a unique challenge for investigation. In a liquid-phase continuous-flow system, reactants A and B are swiftly pushed into the mixing chamber, where mixing occurs within 1 ms. The reaction mixture then flows through an observation tube, and one measures light absorption to determine species concentrations at various points of the tube. This method is most appropriate when relatively large volumes of reactants...

Fast Fourier Transform

The Fast Fourier Transform (FFT) is a computational algorithm designed to compute the Discrete Fourier Transform (DFT) efficiently. By breaking down the calculations into smaller, manageable sections, the FFT significantly reduces the computational complexity involved. Direct computation of an N-point DFT requires N2 complex multiplications, whereas the FFT algorithm needs only (N/2)log2N multiplications, offering a much faster performance. The computational efficiency of the FFT becomes...
FAQs
The stain’s selectivity comes from the interaction between its copper phthalocyanine dye and myelin lipoproteins. In practice, this chemical affinity produces a blue signal that follows myelinated fibers more clearly than surrounding gray matter. That contrast supports structural mapping rather than merely coloring tissue visually.
Differentiation with lithium carbonate and ethanol is a control step that removes excess dye from gray matter while retaining the blue signal associated with myelin. This selective clearing increases contrast between white and gray matter, helping investigators distinguish genuine myelinated structures from nonspecific background in tissue sections.
Counterstains add cellular and tissue context around the myelin-specific signal. When used with Luxol Fast Blue, they support interpretation of neuronal tissue organization and neuropathological changes rather than replacing the primary stain. This combined view helps relate white-matter patterns to surrounding tissue architecture during microscopic assessment.
A practical workflow begins with applying the stain to neural tissue, followed by controlled differentiation using lithium carbonate and ethanol. Excess signal is removed from gray matter while myelin-associated blue remains. Researchers may then use counterstains to add organizational context for microscopic interpretation of the section.
Luxol Fast Blue is especially useful when the research question concerns white-matter anatomy, myelin integrity, or loss of myelinated tissue. In brain and spinal cord samples, staining can help map structures and reveal demyelination or white-matter loss. This makes it relevant to neuropathological studies, including investigations of multiple sclerosis.
Interpretation should focus on the distribution and preservation of the blue myelin-associated signal, not on color alone. Staining patterns can be considered alongside the tissue context revealed by counterstains. In this way, Luxol Fast Blue findings help distinguish organized white matter from patterns associated with demyelination or white-matter loss.
