Biological Activity
Maltoheptaose modifies the DMNPB photoprotective group, improves the resistance of self-assembled monolayer (SAM) to nonspecific protein adsorption and inhibits nonspecific cell adhesion[1].
Maltoheptaose binds to CymE protein in K. oxytoca (KD=70 μM), and can be used as the energy source for growth of K. oxytoca[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

H2O : ≥ 250 mg/mL (216.83 mM)
* "≥" means soluble, but saturation unknown.
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (protect from light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.
