Diagnostic Enzymes and Reagents for Assay Development
Creative Enzymes supplies enzymes, assay components, selected kits, and molecular diagnostic reagents for research and in-vitro diagnostic development. The portfolio can be explored by application, catalytic mechanism, assay target, advanced reagent function, or molecular diagnostic workflow.
Because the same enzyme may serve different roles in different methods, product selection should consider the intended analyte or target, sample matrix, reaction principle, detection format, instrument or device, formulation, storage conditions, and required analytical performance.
Application-based categories help users identify enzymes according to the analytical or diagnostic workflow in which they are intended to be used.

Lipid Metabolism Diagnostic Enzymes
Lipid-related assays use coordinated enzyme reactions for total cholesterol, triglycerides, non-esterified fatty acids (NEFA), lipoprotein-associated cholesterol, and total bile acids. Representative components include cholesterol esterase, cholesterol oxidase, lipases, glycerol kinase, glycerol-3-phosphate oxidase, and acyl-CoA enzymes.

Digital PCR-Compatible Enzymes and Premixes
Digital PCR requires reaction chemistry that remains robust after partitioning into droplets, chambers, or other formats. Evaluation may include cluster separation, low-copy performance, partition compatibility, inhibition, and platform-specific materials.
Quality attributes and acceptance criteria vary by product and intended use. Depending on the material, available documentation may include product specifications, certificates of analysis, activity data, purity information, storage conditions, and stability or application data. Please confirm the current specification and documentation package for the individual product before procurement, method transfer, or validation.
Unless a specific product is identified as having a regulatory authorization or a different intended-use status, these materials should be treated as research-use and assay-development components rather than as finished clinical diagnostic devices or therapeutic products.
