Multiplexed diagnostic to recognize concentrations of related proteins and peptides

Abstract

Disclosed are methods and systems for determining concentrations of a target molecule and a variant thereof in a sample. The sample can comprise or be suspected to comprise a target molecule and at least one variant thereof and is exposed to one or more recognition elements that bind to the target molecule and/or the at least one variant. A signal is detected that is associated with the binding of the target molecule and/or a signal is detected that is associated with the binding of the at least one variant to the one or more recognition elements. The concentration of the target molecule and/or the at least one variant thereof is determined based on the signals. The system can comprise a receiver adapted to receive a sample comprising or suspected to comprise a target molecule and the at least one variant thereof, the receiver comprising one or more recognition elements that bind to one or more epitopes in the target molecule and/or the at least one variant thereof.

Dependencies are inferred from the claim text.
