1,700+ technical articles by Aladdin Scientific's scientists on reagent selection, reaction mechanisms, assay design and formulation. New every week.
Fixative selection directly affects tissue morphology, antigen preservation, cellular structure, and downstream staining results. Routine tissue fixation, immunostaining, cytological preparation, frozen sectioning, and electron microscopy samples have different requirements for fixatives. ...
Bilirubin detection is mainly used to evaluate changes related to heme metabolism, hepatobiliary excretory function, cholestasis, neonatal jaundice, and hepatocellular injury. In clinical and research settings, total bilirubin, direct bilirubin, and indirect bilirubin are commonly measured. ...
Carboxymethyl cellulose (CMC) and its sodium salt (CMC-Na) can be used in cellulase substrate systems, enzyme-producing microbial induction cultures, exogenous polysaccharide models in soil studies, particle suspension stabilization, suspension dosing of poorly soluble compounds, film-forming ...
Reducing sugar detection is used to determine whether a sample contains sugars with reducing properties and to further evaluate sugar content, enzymatic hydrolysis efficiency, fermentation substrate consumption, or sugar composition in food and biological samples. Fehling’s reagent, ...
Electrode solutions are used in multiple steps, including calibration, storage, soaking, cleaning, internal filling, ionic strength adjustment, and standard curve establishment. For pH electrodes, ORP combination electrodes, conductivity electrodes, and ion-selective electrodes, solution ...
Special staining is used to visualize tissue structures, abnormal deposits, and pathogen components that are difficult to distinguish by HE staining. Its advantages include mature methodology, relatively low cost, and intuitive results, making it suitable for fibrosis evaluation, tumor ...
Food hydrocolloids are used for structure construction and stability regulation in food science, colloid chemistry, rheology, and formulation simulation studies. Different hydrocolloids vary in source, gelation mechanism, rheological properties, ion responsiveness, thermal stability, and ...
Bacterial strain cryopreservation is used to preserve strain viability, genetic stability, and phenotypic characteristics over the long term. Common methods include glycerol cryopreservation, compound cryoprotectant-based cryopreservation, ultra-low temperature storage at -80°C, liquid nitrogen ...
In common moisture-curing polyurethane (PU) systems, the material usually contains isocyanate groups, also known as -NCO groups, hereinafter referred to as NCO. After application, moisture from the air, water present in the substrate, or residual water in fillers enters the system and reacts ...
