Question

The plasma membrane of the macrophage cells was able to be seen because it was fluorescently dyed by_____

a) Ethidium bromide
b) Green fluorescent protein (GFP)
c) Rhodamine
d) Fluorescein isothiocyanate (FITC)

Answer 1

The plasma membrane of the macrophage cells was able to be seen because it was fluorescently dyed by Fluorescein isothiocyanate (FITC). FITC is commonly used as a fluorescent dye in various biological experiments, including cell labeling and imaging.

Step-by-step explanation:

The plasma membrane of the macrophage cells was able to be seen because it was fluorescently dyed by Fluorescein isothiocyanate (FITC). FITC is commonly used as a fluorescent dye in various biological experiments, including cell labeling and imaging. When excited by ultraviolet light, FITC emits a green fluorescence, allowing researchers to visualize and study the plasma membrane of macrophage cells.
