CheKine™ Micro PK Assay Kit: Redefining Glycolytic Flux Analysis
PK: The Gatekeeper of Glycolysis
Pyruvate kinase (PK, EC 2.7.1.40) is widely present in animals, plants, microorganisms, and cultured cells, catalyzing the last step of glycolysis—the conversion of phosphoenolpyruvate to pyruvate[reference:72]. Glycolytic flux rewiring drives 80% of oncogenic transformation and metabolic disorders[reference:73].

| Detection Limit | 0.05 mU/mL (10x more sensitive)[reference:74] | 0.5 mU/mL |
| Sample Volume | 1–5 µL (20x lower)[reference:75][reference:76] | 50–100 µL |
| Workflow Time | 20 minutes[reference:77] | 1+ hours |
| Specificity | >97%[reference:78] | ~70% |
| Inter-assay CV | <2.5%[reference:79] | 15% |
| Dynamic Range | 0.1–100 mU/mL[reference:80] | Narrower |
| ATP Interference | Minimized[reference:81] | 25% false positives |
Technical Innovation: LDH-Coupled Detection
KTB1120 leverages a proprietary lactate dehydrogenase-coupled system that quantifies PK-catalyzed phosphoenolpyruvate conversion via NADH consumption (λ=340 nm, ε=6,220 M⁻¹cm⁻¹)[reference:82]. No toxic perchloric acid, no hazardous waste[reference:83].
Applications Validated in High-Impact Journals
Cancer Metabolism — A Warburg effect lab studying lung cancer metabolic rewiring adopted KTB1120 to profile 2 µL A549 spheroid lysates[reference:84]. The kit's micron-scale sensitivity revealed a 40% PK surge in EGFR-mutant vs. wild-type cells—linking glycolytic addiction to 35% tumor growth[reference:85].
Published in Nature Metabolism[reference:86].
Agritech — A team engineering drought-resistant maize used KTB1120 to test 3 µL root extracts[reference:87]. Fifteen-minute processing identified a 35% PK drop in transgenic lines, correlating with 30% higher yield under water stress[reference:88].
Published in Plant Biotechnology Journal[reference:89].
Drug Discovery — CROs leverage KTB1120 for antidiabetic drug screening: 3,000 samples/week processed with 98% reproducibility, slashing costs by 40% vs. LC-MS methods[reference:90].
The Bottom Line
For researchers studying Warburg effect, metabolic disorders, or drug efficacy, KTB1120 delivers the sensitivity, speed, and specificity that modern glycolytic research demands[reference:91].
