Biological Activity

Methyl β-D-Galactopyranoside is an endogenous metabolite and a monovalent carbohydrate ligand that serves as a substrate or inhibitor for galactoside-binding proteins, including galectin-3. By engaging the carbohydrate-recognition domain of galectins, it disrupts carbohydrate-mediated cellular recognition and lectin-glycan signaling pathways. This interaction modulates downstream cellular phenotypes, including cell-cell interactions and cell adhesion processes.

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).
