Abstract
Serum albumin and a serum .gamma.-globulin are separated by filtration from each other in a solution of a mixture thereof by using an ultrafiltration membrane. The ultrafiltration membrane has a fractionation molecular weight of about 100,000. The total protein concentration and salt concentration in the mixture solution to be forced through the membrane are adjusted to not more than 4 g/dl and not more than 0.6 mole/l, respectively. Also, the pH of the solution is adjusted to a value of from about 3.8 to about 4.7.
