Ordering Information

Biological Activity

D-(+)-Raffinose is a naturally occurring trisaccharide composed of galactose, glucose, and fructose that functions as a carbohydrate osmotic protectant and metabolic antioxidant. It acts by scavenging reactive oxygen species, particularly hydroxyl radicals, to protect cellular membranes and organelles against oxidative damage. These cytoprotective functions help maintain metabolic homeostasis and prevent cellular degradation under environmental and physiological stress conditions. [1]

Solubility

Batch:
All in vitro solubility values are batch-tested experimental data (non-literature values).
Solvent Solubility & Note
DMSO 100 mg/mL (168.2 mM)
(Moisture-contaminated DMSO may reduce solubility. Use fresh, anhydrous DMSO. The recommended stock concentration is 10 mM in DMSO.)
FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
