Title:
SYNTHETIC ADSORBENT, ANTIBODY PURIFICATION METHOD, AND ANTIBODY PRODUCTION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/260091
Kind Code:
A1
Abstract:
In this synthetic adsorbent, the maximum value of a differential pore volume (mL/g) determined under pressure conditions from 0.5 psia to 30.0 psia as measured by the following method exceeds 0.05 mL/g.
1. The pressure in a sample container including the synthetic adsorbent being dried is reduced to 10 Pa or lower, and mercury as prescribed in JIS K8572 is degassed by reducing pressure thereof to 10 Pa or lower and is loaded in the sample container at a pressure of 0.5 psia. 2. The mercury intrusion amount is measured while the pressure in the sample container loaded with the mercury is incrementally raised from 0.5 psia to 30.0 psia. 3. The differential pore volume (mL/g) is determined by dividing, by a measured synthetic adsorbent amount, the increase amount of the mercury intrusion amount when the pressure is increased by a one-step pressure calculated on the basis of the mercury intrusion amount measured in 2 above.
