BIOS 242 Week 3 Assignment; Lab 5 of 14 Onsite; Differential Staining Learning Objectives: Explain the principle of differential staining Apply differential staining to identify bacteria Differential stain uses two or more stains to specifically stain certain structures or cellular components which cannot be easily observed using simple stains. Differential staining principles are based upon the specific chemical nature and composition of cellular components and therefore, different s...

BIOS 242 Week 2 Assignment; Lab 4 of 14 Onsite; Simple Staining Lab 4: Simple Staining Learning Objectives: To learn about principle of staining To learn the process of simple stain To prepare wet mount slides In light microscopy, colored dyes, called stains are used to improve contrast between the specimen and the background surrounding the specimen. Staining makes visualization of the specimen easier due to increased contrast. This is crucial for specimens that are mostl...
