MUMBAI, India, Sept. 26 -- Intellectual Property India has published a patent application (202517056231 A) filed by Jnc Corporation, Tokyo, on June 11, for 'porous particles, liquid chromatography carrier, liquid chromatography apparatus, and method for separating/purifying biopolymer.'
Inventor(s) include Takizawa Kazuhiro; Matsumoto Yoshihiro; Iwamoto Eri; Kadoi Kenji; and Nakama Tsuyoshi.
The application for the patent was published on Sept. 26, under issue no. 39/2025.
According to the abstract released by the Intellectual Property India: "The purpose of the present invention is to provide a technology for performing purification of a biomedicine or the like at a high processing speed using a conventional apparatus in which a column is filled with a filler. Provided are porous particles which are characterized in that each of the porous particles has an approximately spherical shape and has a communicating pore structure composed of a three-dimensional network-like framework and a void formed in the framework, wherein, in each of the porous particles, the communicating pore penetrates through from the surface of the particle to the inside of the particle. The porous particles are also characterized in that, when a column having an inner diameter of 0.78 cm and a length of 30 cm is filled with the porous particles and a slurry containing 5 mg/mL of silica microparticles each having a particle diameter of 100 nm is passed through the column at a column temperature of 25 C and a flow rate of 0.4 mL/ min using pure water as a mobile phase, the retention time of the silica microparticles is 15.0 minutes or more."
The patent application was internationally filed on Mar. 04, 2024, under International application No.PCT/JP2024/007973.
