Antibody Biomarkers: Direct Indicators of Disease Status
Profiling humoral antibodies enables the discovery of targetable proteins and pathogenic antibodies, as well as uncovering exploitable protective antibodies to advance precision medicine. Antibodies possess key characteristics of ideal biomarkers, as listed to the right.
Manifest Early
Produced early in protective and pathogenic processes
Predictive
Level correlates with process intensity
Abundant
High concentration in minimal sample volume
Stable
Easily transported, stored, and handled
Specific
Highly specific and stable antibody-antigen binding
Accessible
Present in peripheral fluids and tissues
