Beta-1,4-Galactosyltransferase 1 (B4GALT1) Bovine Recombinant Protein

The Golgi complex form catalyzes the production of lactose in the lactating mammary gland and could also be responsible for the synthesis of complex-type N-linked oligosaccharides in many glycoproteins as well as the carbohydrate moieties of glycolipids. The cell surface form functions as a recognition molecule during a variety of cell to cell and cell to matrix interactions, as those occurring during development and egg fertilization, by binding to specific oligosaccharide ligands on opposing cells or in the extracellular matrix.

Small volumes of B4GALT1 recombinant protein vial(s) may occasionally become entrapped in the seal of the product vial during shipment and storage. If necessary, briefly centrifuge the vial on a tabletop centrifuge to dislodge any liquid in the container`s cap. Certain products may require to ship with dry ice and additional dry ice fee may apply.

MBS963398 is a recombinant protein targeting B4GALT1. Also known as Recombinant Bovine Beta-1,4-galactosyltransferase 1. Host: E Coli or Yeast or Baculovirus or Mammalian Cell.
