  • FunctionRegulatory subunit of lactose synthase, changes the substrate specificity of galactosyltransferase in the mammary gland making glucose a good acceptor substrate for this enzyme. This enables LS to synthesize lactose, the major carbohydrate component of milk. In other tissues, galactosyltransferase transfers galactose onto the N-acetylglucosamine of the oligosaccharide chains in glycoproteins.
  • Tissue specificityMammary gland specific. Secreted in milk.
  • Sequence similaritiesBelongs to the glycosyl hydrolase 22 family.
  • Cellular localizationSecreted.

  • ICC/IF image of ab20212 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal Goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab20212, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 Goat anti-Mouse IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

The histology was carried out on frozen sections (10ug) of lactating mammary glands.

It seems that lactating tissue is the most appropriate positive control, as normal and cancerous tissue does not appear to express alpha lactalbumin accordi...
