Biological Activity

Miglitol is an oral anti-diabetic agent that functions as a potent intestinal alpha-glucosidase inhibitor. By selectively targeting and inhibiting membrane-bound intestinal alpha-glucosidase enzymes, miglitol delays the hydrolysis and cleavage of complex carbohydrates, including disaccharides and oligosaccharides, into absorbable monosaccharides. This targeted enzymatic inhibition prevents rapid luminal glucose absorption and effectively dampens postprandial blood glucose spikes.

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).
