  • Fractionator and method of fractionation
    Patent number: 7795010
    Abstract: The following is disclosed: (1) a membrane fractionator including a filtration section, a concentrating section, a recovery section and a liquid feed pump, wherein a flow channel connecting the filtration section, concentrating section and recovery section to each other constitutes a closed circuitry; (2) a method of biocomponent separation, characterized in that a sample derived from biocomponents is fed into an antibody adsorption membrane separation system having an antibody capable of adsorbing specified protein internally accommodated in the middle or a rear part of a membrane separation system that in the absence of antibodies adsorbing proteins, exhibits a permeation ratio between human alpha1-microglobulin and human albumin of 1.
