    摘要: A blood purification apparatus includes a blood circuit, a waste liquid circuit, citric acid solution supply means, and calcium solution supply means. The blood purification apparatus is configured to calculate a total calcium flow rate of a waste liquid from a total calcium concentration in the waste liquid in the waste liquid circuit when a citric acid solution is supplied from the citric acid solution supply means and a waste liquid flow rate in the waste liquid circuit, and determine a supply flow rate of a calcium solution in the calcium solution supply means from the total calcium flow rate in the waste liquid.

    摘要: The present invention provides a method for purifying a protein, comprising: providing a solution containing a monomer and aggregates of the protein of interest; a purification step of removing the aggregates of the protein of interest using a cation-exchange chromatographic support media to obtain a purified solution of the monomer, the cation-exchange chromatographic support media comprising at least one type of weak cation-exchange group and having a cation-exchange group density higher than 30 mmol/L; and a virus removal step of removing viruses from the purified solution using a virus removal membrane having a virus logarithmic reduction value of 3 or more.
