Patent ID: 8148111

Claim:
A carrier for cell culture, comprising: a particle (A) of a crosslinked poly(meth)acrylic acid or a salt thereof; and an artificial polypeptide (P) having at least one cell-adhesive minimal amino acid sequence (X) selected from the group consisting of an Arg Gly Asp sequence, a Leu Asp Val sequence, a Leu Arg Glu sequence, a His Ala Val sequence, an Arg Glu Asp Val sequence (1), a Tyr Ile Gly Ser Arg sequence (2), a Pro Asp Ser Gly Arg sequence (3), an Arg Tyr Val Val Leu Pro Arg sequence (4), a Leu Gly Thr Ile Pro Gly sequence (5), an Arg Asn Ile Ala Glu Ile Ile Lys Asp Ile sequence (6), an Ile Lys Val Ala Val sequence (7), an Asp Gly Glu Ala sequence (8), a Gly Val Lys Gly Asp Lys Gly Asn Pro Gly Trp Pro Gly Ala Pro sequence (9), a Gly Glu Phe Tyr Phe Asp Leu Arg Leu Lys Gly Asp Lys sequence (10), a Tyr Lys Leu Asn Val Asn Asp Ser sequence (11), an Ala Lys Pro Ser Tyr Pro Pro Thr Tyr Lys sequence (12), an Asn Arg Trp His Ser Ile Tyr Ile Thr Arg Phe Gly sequence (13), a Thr Trp Tyr Lys Ile Ala Phe Gln Arg Asn Arg Lys sequence (14), an Arg Lys Arg Leu Gln Val Gln Leu Ser Ile Arg Thr (15), and a Pro His Ser Arg Asn (16) wherein the content of the artificial polypeptide (P) is 500 ng/g to 50 mg/g based on dry weight of the carrier for cell culture; the carrier for cell culture has a water retention value of from 10 to 28 g/g; and the particle (A) and the artificial polypeptide (P) are bonded together.
