Abstract: The present invention relates to a method for coating a solid support which is suitable for being used in cell culture applications. The method comprises a step in which a solution of a carrier protein, which comprises attached thereto or as a part of its amino acid sequence at least one cell function- modulating peptide sequence, is heated to at least 50° C. and incubated same under conditions which result in the formation of soluble carrier protein aggregates comprising between 2 and 1000 protein molecules. Subsequently, the protein aggregates are brought into contact with the solid support under conditions that allow for the non-covalent adsorption of the aggregates to the support. The invention also relates to a coated solid support having non-covalently adsorbed on its surface at least one of the above-mentioned aggregate of carrier proteins aggregates.
