Patent number: 10442843Abstract: It has been believed that promoting the assembly of polysomes composed of many ribosomes attached to mRNA is very effective for highly efficient protein synthesis. However, the mechanism for p180 protein's capability of promoting polysome formation has been yet to be elucidated. The inventors of the present application newly discovered SF3b4 protein as a protein that specifically interacts with the coiled-coil domain of p180 protein, a responsible region for its capability of promoting polysome formation, and which is capable of promoting mRNA localization to an endoplasmic reticulum (ER). The inventors also found that, in cells capable of highly expressing both p180 protein and a protein promoting mRNA localization to an endoplasmic reticulum (ER) (e.g., SF3b4 protein), the mRNA localization to the endoplasmic reticulum can be significantly elevated so that the secretory capacity in cultured cells can be enhanced.Type: GrantFiled: August 24, 2017Date of Patent: October 15, 2019Assignee: NIPPI, INCORPORATEDInventors: Tomonori Ueno, Yuki Taga, Kiyoko Goto, Yuko Kaku

Patent number: 9617298Abstract: Disclosed is a collagen powder and/or a collagen derivative powder, which are obtained by dispersing in a hydrophilic organic solvent a crude collagen precipitate which comprises 12 to 50% by mass of a collagen precipitate and/or a collagen derivative precipitate having an average particle size of 1 to 1,000 ?m, recovering solids and then drying the solids. By dispersing the crude collagen precipitate in the hydrophilic organic solvent, the resulting precipitates can be dehydrated, so that drying of the thus obtained solids can be done by air-drying. In addition, the resulting collagen powder and/or collagen derivative powder exhibit excellent solubility due to an increased specific surface area and also have excellent ease of handling with the average particle size being 8 to 1,000 ?m.Type: GrantFiled: July 29, 2011Date of Patent: April 11, 2017Assignee: NIPPI, INCORPORATEDInventors: Keisuke Tanaka, Takayuki Ogura, Shunji Hattori, Koichi Matsuda, Yoshikatsu Kobayashi, Shoji Oi

Patent number: 9346058Abstract: Provided is a unit which is capable of readily grinding and collecting a small amount of a sample which is difficult to be ground. The unit for grinding a sample comprises a club-shaped pestle and a mortar into which the pestle can be inserted, wherein the pestle comprises a roughened taper located at at least one end of its pestle body, wherein the mortar is a tube with an inverted frustoconical bottom, and the surface of the mortar where the taper of the pestle contacts the inverted frustoconical bottom when the pestle is inserted into the mortar is roughened, and wherein the angle of the taper with respect to the longitudinal centerline of the pestle is substantially equal to the angle of the inner wall of the inverted frustoconical bottom with respect to the longitudinal centerline of the mortar. The roughened taper and surface improve grinding efficiency.Type: GrantFiled: May 25, 2012Date of Patent: May 24, 2016Assignee: Nippi, IncorporatedInventors: Takuji Yamamoto, Kiyonori Higa, Shunji Hattori
