1,700+ technical articles by Aladdin Scientific's scientists on reagent selection, reaction mechanisms, assay design and formulation. New every week.
RNA structure analysis often requires distinguishing single-stranded regions, double-stranded regions, stacked regions, and differences in structural accessibility. RNase T1, RNase A, RNase V1, and S1 nuclease can be used as structural probes. By selectively cleaving different conformational or ...
In Alzheimer’s disease models, cholinergic detection should not focus only on measuring acetylcholine or acetylcholinesterase separately. The key is to assess the relationship among neurotransmitter levels, enzyme activity changes, cholinergic neuronal injury, and inflammatory responses. When ...
Apolipoproteins (Apos) are important protein components of lipoprotein particles. They participate in the transport of triglycerides, cholesterol, phospholipids, and lipid-soluble molecules, and determine the interactions between lipoproteins and receptors, enzymes, and transport proteins.
Autophagy is a cellular quality control system that delivers cytoplasmic components, damaged organelles, protein aggregates, or intracellular pathogens to lysosomes for degradation. Its core significance is not simply “increased degradation,” but rather the maintenance of cellular ...
Mast cell observation focuses on granule visualization, metachromatic reactions, and assessment of degranulation status. Connective tissue observation focuses more on collagen fibers, elastic fibers, reticular fibers, matrix mucopolysaccharides, and tissue structural remodeling. Staining methods ...
Apoptosis is a form of programmed cell death regulated by genes and protein networks. It mainly functions to eliminate senescent, damaged, abnormally proliferating, or functionally imbalanced cells. Typical apoptosis is characterized by cell shrinkage, chromatin condensation, DNA fragmentation, ...
Root tip squash preparations are mainly used for mitosis observation, chromosome counting, and preliminary karyotype screening. Pollen mother cells are mainly used for meiosis observation, including bivalents, chromosome bridges, lagging chromosomes, and micronuclei. The staining system should ...
The core of carbon-nitrogen metabolic crosstalk lies in the dynamic conversion between carbon skeletons and nitrogen flow. Glutamate and α-ketoglutarate form key hubs connecting the TCA cycle, transamination reactions, glutamine metabolism, and amino acid biosynthesis. Their changes reflect not ...
Protein tyrosine kinases (PTKs) transfer the γ-phosphate group of ATP to tyrosine residues on protein substrates and participate in the regulation of cell proliferation, differentiation, migration, metabolism, and survival. PTKs mainly include receptor tyrosine kinases (RTKs) and nonreceptor ...
