Question

Which stain is used for negative staining for virus?

Answer 1

Hello dear............



It can also be used to stain cells that are too delicate to be heat-fixed.

It is also used to prepare biological samples for electron microscopy.

It is used to view viruses, bacteria, bacterial flagella, biological membrane structures and proteins or protein aggregates, which all have a low electron-scattering power.

Answer 2

Explanation:

To heighten the contrast between viruses and the background, use is made of electron-dense "stains". These are usually compounds of heavy metals of high atomic number, that serve to scatter the electrons from regions covered with the stain.
