Abstract
A method for purifying fibrinogen includes steps of: (a) precipitating fibrinogen of a fibrinogen-containing solution by adding glycine to the solution for a concentration of glycine to be 1.5 to 2.5M, and then removing a supernatant and recovering a precipitate (1glycine precipitation); (b) dissolving the precipitate of 1glycine precipitation of step (a) in a dissolution buffer to obtain a solution, precipitating the solution by adding glycine thereto for a concentration of glycine to be 0.2 to 1.2M, and recovering a supernatant (2glycine precipitation); (c) precipitating the supernatant of step (b) by adding glycine thereto for a concentration of glycine to be 1.5 to 2.5M, and recovering a precipitate (3glycine precipitation); and (d) dissolving the precipitate of step (c) in a dissolution buffer to obtain a solution, and subjecting the solution to nanofiltration using a nanofilter.
