Negative staining is used when it is important to be able to view the bacteria without using harsh stains or performing the heat fixing technique that could possibly distort or change the shape of the bacteria.

India ink is a negative stain that colors the background brown, leaving the cells bright and visible. A differential staining technique is a procedure that allows the observer to visually distinguish between different types of bacterial cells based on the idea that not all cell types stain equally.

Consult care labels for small rugs to determine whether they should be dry-cleaned, spot-cleaned, or laundered. A dry-cleaning-only label might indicate that a rug is not colorfast. Test before spot-cleaning. When you determine that a rug is washable, machine-wash it on the delicate cycle.

Intact yeast cells are Gram positive but broken or disrupted cells are Gram negative. A counterstain with methyl green provides differential staining between cell wall and cytoplasm. The cells and cell fragments are dried on a slide and stained hy a standard Gram stain.

This is basic transfusion science. Basically AB-positive and AB-negative blood types have one important difference. AB-positive and AB-negative blood types both contain A and B antigens on their red cell surfaces. ... AB-positive and AB-negative blood types both contain A and B antigens on their red cell surfaces.

Solid stains are opaque stains with lots of pigment that covers the wood grain. The other big difference is that the semi-transparent stain penetrates into the wood while the solid stain is a film forming stain that forms a layer on the surface of the wood.

Basic: A stain that has positively charged ions (cationic) that will react with material that is negatively charged. The surface of bacteria is somewhat negatively charged, therefore basic dyes will permeate the cell wall and will be attracted to negative charges of the bacteria and stain the bacteria.

There is a difference. Stains are made of colored pigments that stick in the grain and pores of the wood surface while dyes consist of microscopic particles that penetrate the wood itself. ... When mixed with the proper solvent, dye crystals dissociate into individual molecules.
