The core of Papanicolaou staining is not coloration by a single dye, but the formation of layered differences among nuclei, keratinized components, cytoplasm of mature squamous epithelial cells, and cytoplasm of non-keratinized cells through nuclear staining, keratinized cytoplasmic staining, ...
In tissue sections, collagen fibers, muscle fibers, and fibrin may all appear as fibrous, fascicular, cord-like, or reticular structures. In routine hematoxylin and eosin (HE) staining, they often show varying degrees of eosinophilic red staining. Their differentiation should be based on tissue ...
Isocitrate dehydrogenase (IDH) is a key enzyme family involved in the tricarboxylic acid cycle, NADPH supply, α-ketoglutarate generation, and cellular redox homeostasis. In mammalian cells, the major isoenzymes include IDH1, IDH2, and IDH3. IDH1 and IDH2 are NADP⁺-dependent enzymes and are ...
Aldehyde dehydrogenase (ALDH) is a class of oxidoreductases that use NAD+ or NADP+ as cofactors and mainly catalyze the oxidation of aldehyde substrates into corresponding carboxylic acids. Aldehydes can originate from ethanol metabolism, lipid peroxidation, sugar oxidation, drug metabolism, and ...
Gentamicin is an aminoglycoside antibiotic used in antibacterial therapy and cell culture contamination control. Because it can induce oxidative stress, mitochondrial dysfunction, lysosomal abnormalities, apoptosis, and necrosis-like injury, gentamicin is often used to construct injury models in ...
Sperm staining evaluation is a fundamental technique in male reproductive research, assisted reproduction experiments, animal breeding assessment, and reproductive toxicology analysis. Different staining methods can be used to assess sperm morphology, viability, plasma membrane integrity, ...
Acrylic resins are polymers or copolymers formed through the polymerization of acrylic acid, methacrylic acid, and their ester monomers as the main structural units. In coatings, acrylic resins are commonly used as film-forming materials or primary binder resins. They influence coating-film ...
Urease catalyzes the hydrolysis of urea to produce ammonia and carbon dioxide. It is a key enzymatic node in soil nitrogen cycling, microbial metabolism, clinical testing, dairy quality analysis, fermentation process control, and environmental ammonia nitrogen monitoring. Detection systems ...
The performance of epoxy resin is not determined by a single factor. For the same epoxy resin, changing the curing agent, filler, additive, or curing process may lead to a final material with completely different strength, toughness, heat resistance, chemical resistance, electrical insulation, ...
