Abstract

A cell culturing system, methods for the preparation thereof, and methods for affixing other biologically active moieties to a substrate are provided. Said cell culturing system comprises: a substrate; a coating thereon of a sterile formulation comprising polyphenolic protein containing from about 35 to 100% by weight pure bioadhesive polyphenolic protein having the repeating decapeptide unit: ##STR1## wherein N is a whole number ranging from about 10 to about 100, wherein each X is independently selected from the group consisting of hydroxyl and hydrogen, and wherein each R is independently selected from the group consisting of hydrogen and methyl; viable cells affixed to said coated substrate; and a nutritive medium contacting said cells, whereby said cells perform normal metabolic cell functions.
