General description

Lactose is an important disaccharide in human nutrition, culinary goods, and pharmaceuticals. β-lactose is an isomeric form that is rarely found in nature.

Application

β-Lactose has been used:
  • to treat HL-1 cells followed by phorbol dibutyrate (PDB) treatment to study if protein kinase C (PKC) -stimulated accumulation is mediated through galectin-3
  • as a component of a media to analyze the extracellular production of protein
  • along with recombinant galectin-3 to treat cells for the detection of galectin-3 cell surface binding
  • along with recombinant galectin-3 or a control protein to stimulate T cells for apoptosis assay
