The invention relates to a method for providing a proteinaceous coating on
a medical implant, comprising the steps of: submersing the implant in a
first aqueous solution comprising a protein and magnesium, calcium and
phosphate ions through which a gaseous weak acid is passed; degassing the
solution; allowing a coating to precipitate onto the implant; submersing
the coated implant in a second solution to redissolve the magnesium,
calcium and phosphate ions and to obtain the proteinaceous coating.
