Human IgG4 anti-PD-1 antibodies (JS001) were evaluated for RO bioanalysis. A 100 μl blood sample was aliquoted into two different tubes labeled as RO tube and total receptor tube (TR tube), respectively. Blood sample in TR tube was incubated with 3 μg of JS001, or human IgG4 isotype control antibody (Biovision, CA, USA) for 30 min at 25◦C.
按原文的描述应该是3 ug的JS001和human IgG4 isotype一起组成toal管,RO管的处理应该在后面3ug的JS001是真正的toal值human IgG4 isotype应该是为了证明这个toal是我们要的。
The whole blood sample was incubated with JS001 at a twofold serial dilution starting from 330 pmol/l 15-times in order to determine the optimal drug concentration for low RO (LRO) and high RO (HRO) via method。 |
