CheKine™ Micro FBP Activity Assay Kit: Mastering Gluconeogenesis Research
FBP: The Rate-Limiting Enzyme of Gluconeogenesis
Fructose-1,6-bisphosphatase (FBP), also known as fructose-1,6-diphosphatase, plays a key role in gluconeogenesis and the synthesis of sucrose, an assimilate of photosynthesis[reference:50]. It catalyzes the conversion of fructose-1,6-diphosphate and water to produce fructose-6-phosphate and inorganic phosphorus[reference:51]—a rate-limiting step in the gluconeogenic pathway[reference:52]. FBP dysregulation is implicated in diabetes, cancer metabolism, and plant stress responses.

The NADPH-Coupled Detection Principle
In this kit, FBP catalyzes fructose-1,6-diphosphate and water to produce fructose-6-phosphate and inorganic phosphorus[reference:58]. Glucose-6-phosphate isomerase and glucose-6-phosphate dehydrogenase added in the reaction system catalyze glucose-6-phosphate and NADPH in turn, and FBP activity is calculated by measuring the increase rate of NADPH at 340 nm[reference:59].
Why FBP Matters in Your Research
FBP is essential for:
- Gluconeogenesis — understanding glucose production in liver and kidney
- Diabetes research — FBP dysregulation in insulin resistance
- Cancer metabolism — metabolic reprogramming in tumors
- Plant science — sucrose synthesis and photosynthetic carbon partitioning
- Drug discovery — screening FBP inhibitors for metabolic disorders
Validated in High-Impact Research
The kit has been cited in 2 publications, including a study in Cell Death & Differentiation (IF: 13) on the discovery of FBP1 as a novel therapeutic target and asiatic acid-hydrogen sulfide donors accelerating diabetic wound healing[reference:60].
Critical Sample Handling Tips
- If not assayed immediately, samples can be stored at -80°C for one month[reference:61]
- Fresh samples are necessary for good results[reference:62]
- Perform several dilutions to ensure readings are within the standard value range[reference:63]
- Complete the Sample Preparation step before storing samples if not assaying immediately[reference:64]
The Bottom Line
For researchers investigating gluconeogenesis, diabetes, cancer metabolism, or plant carbohydrate metabolism, KTB1331 delivers the sensitivity, specificity, and publication-ready performance that modern metabolic research demands—backed by a Cell Death & Differentiation publication[reference:65].
