Cell culture resin beads possessing cell adhesive polypeptide

Cell culture resin beads possessing cell adhesive polypeptide. Shindo, Yasuhiro; Kurokawa, Masato (Sanyo Chemical Industries, Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 2006042794 A2 16 Feb 2006, 32 pp. (Japanese). (Japan). CODEN: JKXXAF. 137599-18-9 are also occured in this study. APPLICATION: JP 2004-354966 8 Dec 2004. PRIORITY: JP 2004-190285 28 Jun 2004. DOCUMENT TYPE: Patent CA Section: 9 (Biochemical Methods) Cell culture resin beads are provided, which are excellent in cell proliferation ability. The cell culture resin beads in this invention are characterized in that they contain a base polymer (a) and microparticles (b) possessing the apparent sp. gr. smaller than the true sp. gr. of (a). The true sp. gr. (Da) of (a) is preferably 1.050-1.60,. The apparent sp. gr. (Db) of (b) is preferably 0.03-0.98. 137599-18-9 is the cas registry number of certain chemical which is used as reagents here. The difference (Da-Db) between (Da) and (Db) is preferably 0.01-1.58. The content of (b) in the resin beads is preferably 0.01-50 wt. % based on the wt. of the resin beads. The apparent sp. gr. of the resin beads is preferably 1.01-1.05. The base polymer (a) is preferably one kind selected from the group of crosslinked urethane resin, crosslinked epoxy resin, crosslinked vinyl resin and crosslinked ester resin. It is desirable that a polypeptide (P) possessing at least one cell adhesive min. amino acid sequence (X) in a single mol. is contained on the surface of the resin beads. ..
