Diagnostic Enzymes by Applications

Enzymes are the cornerstone of biochemical diagnostics, catalyzing reactions that convert invisible molecular events into quantifiable signals. At Creative Enzymes, we provide a broad range of high-quality diagnostic enzymes designed for diverse clinical and analytical applications. Our enzymes are developed to meet stringent diagnostic-grade standards—including high specific activity, stability, purity, and reproducibility—to ensure consistent assay performance across automated platforms, point-of-care devices, and high-throughput laboratories.

Our application portfolio spans from routine clinical chemistry (such as creatinine, glucose, and cholesterol assays) to emerging molecular diagnostics and environmental or food safety testing. Each enzyme is optimized to perform reliably under physiological conditions and in complex sample matrices like serum, plasma, urine, and saliva.

Blood and Biochemical Diagnostics

Enzymes play a pivotal role in the detection of critical metabolites and biomarkers in blood. Commonly used enzymes include oxidases, dehydrogenases, and transferases, which convert analytes such as glucose, uric acid, lactate, and cholesterol into measurable products through colorimetric, fluorometric, or chemiluminescent reactions.

At Creative Enzymes, our enzyme solutions for blood diagnostics are manufactured under controlled GMP-like conditions, with CV < 3% reproducibility and endotoxin levels below 0.1 EU/mg. These enzymes support the development of assays for parameters including:

  • Glucose (Glucose oxidase, Glucose dehydrogenase)
  • Uric acid (Uricase)
  • Cholesterol (Cholesterol oxidase, Cholesterol esterase)
  • Lactate (Lactate oxidase, Lactate dehydrogenase)

Applications extend to both clinical chemistry analyzers and point-of-care testing (POCT) systems, enabling accurate monitoring of metabolic and cardiovascular health.

Diabetes Monitoring

Enzymatic glucose measurement remains the gold standard for diabetes diagnostics. We offer recombinant and engineered variants of glucose oxidase (GOx) and glucose dehydrogenase (GDH) that exhibit enhanced oxygen independence, minimal interference from maltose or galactose, and improved thermal stability.

These enzymes are integral to glucose meters, biosensors, and continuous glucose monitoring (CGM) systems. Creative Enzymes also provides enzyme stabilization and formulation support, ensuring long shelf-life and reliable signal generation under field-use conditions.

Renal and Pancreatic Function Testing

Renal function diagnostics rely on enzyme-based assays to quantify creatinine, urea, and cystatin C, key indicators of glomerular filtration and kidney health. Our enzyme offerings include:

  • Creatininase / Creatinase / Sarcosine oxidase for multi-step creatinine detection
  • Urease for urea measurement
  • α-Amylase and lipase for pancreatic function evaluation

These enzymes are validated under IFCC and CLSI guidelines and designed for compatibility with automated analyzers, minimizing background noise and improving reaction linearity.

Liver Function and Lipid Metabolism Assays

Liver enzyme activity and lipid metabolism are central to clinical diagnosis. Creative Enzymes supplies high-purity reagents for:

  • Alanine aminotransferase (ALT) and Aspartate aminotransferase (AST) assays
  • Glycerol-3-phosphate oxidase and Triglyceride lipase for triglyceride quantification
  • Cholesterol esterase and cholesterol oxidase for lipid panels

Our formulations demonstrate superior substrate turnover rates and reduced inhibition from serum components, ensuring assay precision even at trace analyte levels.

POCT Biosensors

Point-of-care devices demand enzymes with rapid kinetics, low temperature sensitivity, and minimal signal drift. Creative Enzymes develops and supplies biosensor-grade enzymes with nanomaterial conjugation compatibility for electrochemical, fluorescent, or colorimetric sensors.

Applications include glucose, lactate, uric acid, and triglyceride biosensors. Our R&D team also assists in enzyme immobilization, nano-coating optimization, and long-term stability testing, supporting the integration of enzymatic reactions into miniaturized detection platforms.

Environmental Monitoring

Enzymes are increasingly applied in environmental biosensing to detect pollutants, toxins, and biochemical oxygen demand (BOD). Creative Enzymes provides robust enzyme formulations such as:

  • Laccase and peroxidase for phenol and pesticide detection
  • Dehydrogenases for heavy metal or organic contaminant sensing
  • Catalase and superoxide dismutase for oxidative stress studies

These enzymes enable eco-friendly, rapid, and sensitive alternatives to traditional chemical assays.

Food Safety and Quality Testing

Food industry diagnostics depend on enzymes for detecting contaminants, adulterants, and nutrient levels. Examples include:

  • Amylase and glucose oxidase for carbohydrate profiling
  • Lipase and cholesterol oxidase for lipid testing
  • Protease and peroxidase for freshness and spoilage assessment

Our enzymes maintain activity stability under variable pH and temperature, supporting both rapid tests and continuous production line monitoring systems.

Companion Diagnostics (CDx)

With the expansion of precision medicine, enzyme-based CDx tools are becoming vital in drug development pipelines. Creative Enzymes supports co-development programs for biomarker-driven assays, supplying enzymes with batch-to-batch consistency, validated clinical compatibility, and regulatory-ready documentation.

Applications include immunoenzymatic amplification (e.g., HRP-, AP-, or β-galactosidase-based systems) in therapeutic response assays or genetic mutation detection kits.
