BIOLOGY amp BIOTECHNOLODY DEPARTMENT In our laboratory bacterial morphology form and structure may be examined in two ways By observing living unstained organisms wet mount 2 By . Staining total protein before specific protein de tection techniques provides an assessment of protein transfer efficiency and makes it possible to detect contaminating proteins in the sample and to compare the sample with molecular weight standards A stain is a substance that adheres to a cell, giving the cell color. ..

Different stains have different affinities for different organisms, or different parts of . organisms. They are used to differentiate different types of organisms or to view specific parts of organisms. Differentiate bacteria into two large groups (the Gram Positive and the Gram negative).. Gram status is important in medicine; the presence or absence of a cell wall will change the bacterium's susceptibility to some antibiotics.
