vital dye การใช้

• Cells were then stained with vital dye FDA and observed under fluorescence microscopy.
• Green S is a vital dye, meaning it can be used to cells.
• However, the opaque character of the HRP stain prevented use of vital dye mitotic state of the injected cell's progeny.
• In addition to being able to transfect cells with DNA plasmids coding for fluorescent proteins, the gene gun can be adapted to deliver a wide variety of vital dyes to cells.
• Early embryologists used " vital dyes " ( which would stain but not harm the cells ) to follow movements of individual cells or groups of cells over time in " Xenopus " frog embryos.
• Vital dyes, such as trypan blue or propidium iodide are normally excluded from the inside of healthy cells; however, if the cell membrane has been compromised, they freely cross the membrane and stain intracellular components.
• The first person to develop and use this technique to study cell fate was embryologist Walter Vogt in 1929 . Vogt used small chips of agar impregnated with a vital dye, ( such as Nile Blue or Nile Red ) which he placed on a particular cell or population of cells in " Xenopus " embryos until the dye absorbed into the yolk platelets within the desired cell ( s ).
