Abstract: The present disclosure relates to highly sensitive methods for determining the identity and quantity of one or more proteins in a sample. For example, the present disclosure provides methods for the highly sensitive identification and quantitation of residual host cell proteins in protein samples and can be adapted to identify and quantify proteins in either a targeted or a target-agnostic manner and can be modified to achieve a range of sensitivities appropriate for distinct use cases.
