| titleOfInvention | Intact mass determination of protein conjugated agent compounds |
| abstract | The present invention provides methods and systems for the rapid determination of the intact mass of non-covalently associated antibody heavy chains (HC) and light chains (LC) which result from the attachment of drug conjugates to interchain cysteine residues. By analyzing the antibody-drug conjugate (ADC) using native desalting conditions, the intact-bivalent structure of the ADC, which ordinarily would decompose as a consequence of denaturing chromatographic conditions typically used for LCMS, is maintained. The mass of the desalted ADC is subsequently determined using desolvation and ionization ESI-MS conditions. The methods described herein provide for direct measurement of the intact mass of an ADC conjugated at interchain cysteine residues. The methods described herein also provide for the relative quantitation of the individual ADC species. |
