Introduction  \nIn biomedical research, the discovery and validation of biomarkers have emerged as pivotal processes in advancing precision medicine and improving patient outcome. Biomarkers are measurable indicators such as genes, proteins, metabolites, or other biomolecules that reflect variability influenced by genetic, environmental, and other factors. Among these, proteins are particularly valuable as biomarkers due to their central roles as primary effectors in biological processes, their ability to reveal physiological and pathological states, their accessibility across various biological samples, and the availability of established detection methods.  \nIn clinical settings, biomarkers can be used as risk indicators, for predicting disease progression or recurrence, assessing disease status, monitoring response to treatment, and identifying toxicity of exposure[1]. For example, the Cardio IQ panel assesses cardiovascular risk by analyzing factors such as chole","cbCaia7gux5sirjh","https://ap.wps.com/l/cbCaia7gux5sirjh","pdf",1437021,2,1,40,"English","en",105,"# Introduction\n## Biomarker development and clinical use\n# Protein biomarker\n## Development of protein biomarkers\n## Verification and validation\n# Detection technologies for multiplexing\n## Mass spectrometry-based approaches\n## Affinity-based approaches\n# Comparison and future directions\n## Reproducibility and multi-omics integration\n## High-throughput automation and emerging methods","[{\"question\":\"Why are protein biomarkers central to precision medicine?\",\"answer\":\"Proteins are valuable biomarkers because they reflect physiological and pathological states, are accessible in diverse biological samples, and can be detected using established methods.
