| abstract |
The present disclosure provides, in part, methods for evaluating, identifying, and/or producing (e.g., manufacturing) a CTLA4-Fc fusion protein, e.g., abatacept. In some instances, methods herein allow highly resolved evaluation of abatacept useful for, inter alia, manufacturing abatacept, characterizing abatacept, identifying and/or confirming abatacept, monitoring the structure of abatacept, comparing abatacept preparations made over time or made under different conditions, and/or controlling the structure of abatacept. |
