Expression of human LNalpha4LG4-5 in Pichia yeast / 生物工程学报

ABSTRACT

To carry out the secretive expression of human laminin alpha4 chain LG4-5 module (hLNalpha4LG4-5), recombinant expression plasmid pPICZalphaA-LG45 was constructed by inserting of hLNalpha4LG4-5 cDNA into yeast expression vector pPICZaA. The hLNalpha4LG4-5 protein was expressed in GS115 Pichia yeast strain after induced by methanol, and purified target protein can obviously promote the expansion and adhesion of 293 cells.
