A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...

If your doctor suspects you have an infection, they may order a culture and gram stain to check for bacteria. If bacteria are present, this test can also help your doctor learn if the bacteria are ...

Staining is one of the most important steps in the preparation of biological microscope slides. First destroy the selective permeability of the cell membrane, and then use the dye to immerse the ...

Being a cationic dye, crystal violet can be used to stain negatively charged polymers such as DNA 18 and cell walls of bacteria, the latter of which is partially the basis of Gram staining to ...

Gram staining is a type of differential staining used to distinguish between Gram positive and Gram negative bacterial groups, based on inherent differences in their cell wall constituents. Stains ...

Gram-positive bacteria show blue or purple after Gram-staining in a laboratory test. They have thick cell walls. Gram-negative bacteria show pink or red on staining and have thin walls. They release ...
