CheKine™ Micro Trehalose Assay Kit: The Gold Standard for Stress Response Research
Trehalose: The Stress-Protective Disaccharide
Trehalose is a non-reducing disaccharide widely distributed in bacteria, fungi, plants, and invertebrates. It serves as a universal stress protectant, stabilizing proteins and membranes under dehydration, heat, cold, and oxidative stress. Trehalose accumulation is a hallmark of anhydrobiosis—the ability of organisms to survive extreme desiccation.

The Enzyme-Coupled Specificity Advantage
Traditional trehalose quantification methods (e.g., anthrone) cannot distinguish trehalose from glucose, sucrose, or other sugars—leading to inflated readings and misleading data[reference:86]. KTB1335 employs an enzyme-coupled colorimetric approach based on a Trehalase-GOD-POD cascade reaction system[reference:87]: trehalose is first hydrolyzed into two glucose molecules by trehalase, and then glucose is detected using the GOPOD method[reference:88]. This enzymatic cascade delivers specific trehalose quantification at approximately 505 nm[reference:89] without cross-talk from other sugars[reference:90].
Applications Across Research Fields
- Stress Physiology — tracking trehalose accumulation in drought, heat, and cold stress
- Anhydrobiosis Research — understanding desiccation tolerance in tardigrades, nematodes, and resurrection plants
- Fungal Biology — studying trehalose metabolism in yeast and pathogenic fungi
- Bacterial Stress Responses — trehalose as a compatible solute in osmotic stress
- Insect Physiology — trehalose as the major hemolymph sugar
- Crop Improvement — engineering trehalose accumulation for stress tolerance
Sample Compatibility
The kit can detect biological samples such as animal and plant tissues, cells or bacteria, plasma, serum or other liquid samples[reference:91]. It is recommended for the determination of samples that do not contain soluble sugars other than trehalose[reference:92].
Critical Sample Handling Tips
- Use fresh samples for optimal accuracy
- Complete sample preparation before storing if not assaying immediately
- Run samples and standards in duplicate for optimal precision
The Bottom Line
For researchers investigating stress tolerance, anhydrobiosis, or fungal metabolism, KTB1335 delivers the specificity, sensitivity, and reliability that modern stress physiology research demands—distinguishing trehalose from other sugars at the level of enzyme-substrate recognition[reference:93].
