Overview of Carboxylated Carboxylated 96-well solid plates are advanced polymer-based microplates engineered for covalent coupling of biomolecules through surface carboxyl (-COOH) groups. These plates are essential for high-throughput binding assays, protein immobilization, nucleic acid conjugation, and enzyme-linked reactions where chemical stability and reproducibility are critical. Each well contains a solid,…
Cell Counting Kit-8 (CCK-8): Technical Overview, Reaction Principle, and Quantitative Analysis in Cell Viability Assays
Introduction to Cell Counting Kit-8 (CCK-8) The Cell Counting Kit-8 (CCK-8) is a widely used colorimetric assay designed to quantify viable cells by measuring their metabolic activity. It utilizes a water-soluble tetrazolium salt known as WST-8, which is reduced by cellular dehydrogenases to form a highly water-soluble orange formazan dye.…
Amylase Activity Colorimetric Assay Kit — Technical Overview, Protocol, and Data Analysis
What is amylase and why measure it? Amylases are glycoside hydrolases that cleave α-1,4-glycosidic bonds in starch and related polysaccharides to shorter oligosaccharides and sugars. In research and bioprocess monitoring, quantifying α-amylase activity supports enzyme characterization, fermentation optimization, food and beverage QC, and enzyme engineering—without any diagnostic intent. Background on…
