Human LAMB4 Recombinant Protein (N-His) is a recombinant protein expressed in E. coli, spanning Ser1453-Ser1761, with an N-terminal His tag. Predicted molecular weight: 37.32 kDa. Purity: >90% as determined by SDS-PAGE. Supplied lyophilized from a solution in PBS pH 7.4, 1 mM EDTA, 4% Trehalose, 1% Mannitol. Applications: ELISA, immunogen, SDS-PAGE and Western blot. Laminin subunit beta-4 is a ~193 kDa protein. Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components.
