Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.

Periodic acid-Schiff staining detects tissue carbohydrates and mucosubstances by oxidizing carbohydrate glycol groups with periodic acid to generate aldehydes, which then react with Schiff reagent to produce a magenta reaction product; classic reports established the method for mucin and polysaccharide-containing structures in fixed tissue sections. PAS staining can demonstrate neutral mucins and goblet-cell mucin, but it is not specific for mucin because glycogen and other PAS-positive tissue components can also stain; diastase/PAS-D is used when glycogen removal is needed to distinguish glycogen-dependent PAS signal from non-glycogen PAS-positive mucosubstances.

Alzheimer’s Disease (AD) is a neurodegenerative disorder characterized by a progressive decline in cognitive functions and loss of specific types of neurons and synapses. Alzheimer's symptoms can be simulated in mice by injecting drugs (such as Aβ) or genetically modified.
