Answer:
Stains used for staining living cells and plant cells include Bismarck Brown, DAPI, Hoechst Stains, Neutral Red, Nile Blue, Nile Red / Nile Blue Oxazone, Safranin, Eosin Y, Toluidine blue.
Explanation:
The purpose of staining cells is to make it easier to see the cell or certain components of the cell. Some common stains and their uses are listed below.
- Bismarck Brown stain acid mucins yellow.
- DAPI when attached to DNA, it emits a blue fluorescence.
- Hoechst Stains for staining DNA in living cells.
- Neutral Red for staining nuclei red.
- Nile Blue for staining nuclei blue.
- Nile Red / Nile Blue Oxazone stains intracellular lipid globules red.
- Safranin produces green/yellow fluorescence in the secondary cell wall and red/orange fluorescence in the middle lamella area of the wood cell wall.
- Eosin Y colors the alkaline cell parts pink.
- Toluidine blue is used for staining acidic cell parts dark blue. Good for showing mitosis in plant cells
