Electron Microscopy Sciences Tissue Marking Dye Kit, 5 dyes (5 x 2 oz)

Fast drying dye is ideal for marking tissue biopsies and pathology specimens and can be used with frozen or fixed tissues. It is a specially formulated binding pigment that evenly coats the tissue without penetrating the tissue surface. The marking dyes do not interfere with diagnostic interpretation due to the fact colors are not similar to standard histopathology dyes. It can be used to permanently mark the margins of excised surgical specimens for exact orientation.

Sigma Aldrich Fine Chemicals Biosciences BioTracker 488 Green CSfE

BioTracker SE Cell Proliferation Kits diffuse passively into live cells and are used for long-term cell labeling. They are initially non-fluorescent esters of amine-reactive dyes but are converted to fluorescent dyes by intracellular esterases. The dyes then covalently react with amine groups on intracellular proteins forming fluorescent conjugates that are retained in the cell. Immediately after staining a single bright fluorescent population will be detected by flow cytometry. Each cell division that occurs after labeling is revealed by the appearance of a successively dimmer fluorescent peak on a flow cytometry histogram (fig. 1). Cell proliferation dyes can be used to track cell divisions in vivo or in vitro. The staining can withstand fixation and permeabilization for subsequent immunostaining. Alternative applications of cell proliferation dyes include uniform labeling of cell cytoplasm for microscopy or labeling cells for quantitation of cell number by microplate reader.Spec

Enzo Life Sciences Di-8-ANEPPS (5mg). CAS: 157134-53-7

Di-8-ANEPPS is a member of the ANEP class of membrane potential dyes. These dyes are weakly fluorescent in aqueous media, and become strongly fluorescent upon binding to lipophilic environments such as membranes. A change in the surrounding electronic field demonstrates a membrane potential-dependent shift in excitation spectra. Di-8-ANEPPS is less susceptible for cellular internalization than other ANEP dyes probably due to a sulfonate group. The response is sufficiently fast to detect transient (millisecond) potential changes in excitable cells, including single neurons, cardiac cells and intact brains. Wavelength Maxima: Excitation 498nm, Emission 713nm Alternative name: 4-[2-[6-(Dioctylamino)-2-naphthalenyl]ethenyl]-1-(3-sulfopropyl)-pyridinium, inner salt. Purity: ≥90% (HPLC). Solubility: Soluble in DMSO. Long Term Storage: -20°C.
