CLONING AND EXPRESSION OF COLLAGEN-DERIVED PROTEIN IN E. COLI AND BACULOVIRUS SYSTEM

Abstract Using appropriately designed primers we amplified a 783 bp frag ment of the triple helical portion of human α1-collagen (I) by PCR methods. The expression of this biosynthetic collagen gene and a modified one containing cell adhesion sequences was carried out in a prokaryotic (E. coli) and a eukaryotic (baculovirus) system. The expression products were purified by affinity chromatography.
