Question

which stain is used to stain living cells and plant cells?

Answer 1

Answer:

Hoechst stains - two types of fluorescent stains, 33258 and 33342, these are used to stain DNA in living cells. Iodine - used as a starch indicator. When in solution, starch and iodine turn a dark blue color.

Answer 2

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
