Definition
protein charge variant classifier that classifies a molecular entity population composed of proteins or protein fragments as differing from a reference protein form by having a lower isoelectric point or lower net electric charge under the relevant analytical conditions
Explanatory Notes
The term acidic is used in the conventional charge-variant sense, typically reflecting lower isoelectric point, lower net electric charge, or corresponding behavior in methods such as ion-exchange chromatography or capillary isoelectric focusing.
Examples
- a classifier that classifies a deamidated monoclonal antibody population as an acidic charge variant; a classifier that classifies a sialylated antibody glycoform-enriched population as an acidic charge variant; a classifier that classifies an acidic peak population detected by cation-exchange chromatography; a classifier that classifies a lower-pI protein population detected by capillary isoelectric focusing
