1,700+ technical articles by Aladdin Scientific's scientists on reagent selection, reaction mechanisms, assay design and formulation. New every week.
Eosinophils are an important leukocyte type within the granulocytic lineage. They are mainly involved in the pathological processes of parasitic infection, allergic reactions, asthma, drug reactions, autoimmune inflammation, and certain hematologic diseases. Morphological observation can ...
Romanowsky staining refers to a group of compound staining systems centered on the acidic dye eosin and basic thiazine dyes. It is mainly used for blood smears, bone marrow smears, parasite morphology, cytology smears, and certain microbiological morphology observations.
Chemical fecal occult blood testing uses the peroxidase-like activity of heme in hemoglobin to oxidize chromogenic substrates in the presence of peroxide, thereby indirectly determining whether trace blood components are present in feces.
Microfilaments are mainly formed by the polymerization of actin and are an important component of the cytoskeleton. They participate in the maintenance of cell morphology, adhesion and migration, cytokinesis, endocytic transport, stress fiber formation, and the establishment of cell polarity.
Connective tissue staining is mainly used to distinguish collagen fibers, reticular fibers, elastic fibers, matrix mucopolysaccharides, cartilage matrix, mineralized matrix, and related connective tissue cells.
Azo dye-type indicators refer to a class of organic color-developing reagents that contain an azo bond (—N=N—) in the molecule and can produce color responses through changes in acid-base state, metal complexation, protein binding, or affinity for tissue components.
Triphenylmethane dye-type indicators are a class of organic color-change reagents based on triarylmethane or related lactone/quinoid structures. They are widely used in acid-base titration, non-aqueous titration, complexometric titration, protein assays, histological staining, microbiological ...
Nuclear dyes are important visualization tools used to display cell nuclei, nucleic acid distribution, and cell-cycle status. They are widely applied in fluorescence microscopy, flow cytometry, histopathological staining, cell viability assessment, and apoptosis/necrosis analysis.
Polyester resins used in coatings are not a single, uniform category. Different polyester resins vary in resin structure, reactive functional groups, curing-agent type, application method, and final coating-film structure.
