    Sulforhodamine 101

    From: $228 Sizes: 500 mgCatalog #: 80101

    Sulforhodamine 101 has a longer absorption wavelength than does sulforhodamine B. Like sulforhodamine B and G, in addition to their potential use in cancer drug screening, these fluorescent dyes have been primarily used as polar tracers for the studies of neuronal cell morphology and cell-cell communication.

     
    Product

    Sulforhodamine B

    From: $79 Sizes: 5 gCatalog #: 80100

    Similar to other sulforhodamine dyes, the highly water-soluble sulforhodamine B can also be used as a polar tracer for the studies of cell morphology and neuronal cell-cell communication (1-3). In addition, sulforhodamine B has been shown to be a superior protein stain for use in the quantification of cellular proteins of cultured cells.

     
    Product

    Sulforhodamine G

    From: $141 Sizes: 5 gCatalog #: 80102

    Similar to other sulforhodamine dyes, the highly water-soluble sulforhodamine G can also be used as a polar tracer for the studies of cell morphology and neuronal cell-cell communication (1-3).

    TMR Biocytin

    From: $257 Sizes: 5 mgCatalog #: 92003

    TMR biocytin is a cell-impermeant, fixable polar tracer that combines the tetramethylrhodamine (TAMRA) with biotin and an aldehyde-fixable primary amine.  Polar tracers are commonly used to investigate cell-cell and cell-liposome fusion as well as membrane permeability and transport through gap junctions or cell uptake during pinocytosis.
