Broad Research Applications of Protein Biomarker Discovery

A biomarker is any measurable biological molecules that can be assessed and measured as a potential index of physiological status or pharmacological responses to treatments. Scientists and researchers screen proteins, particularly low-abundance proteins extracted from tissues, blood, urine and other body fluids, to obtain indicators of biological processes.

Identifying these trace proteins demands comprehensive, unbiased proteomic profiling, for which mass spectrometry acts as a powerful tool for large-scale protein identification and quantification. At Novogene, we deploy state-of-the-art mass spectrometers to generate high-throughput, reproducible and ultra-precise data with unparalleled performance. Coupled with our robust sample pretreatment workflows, our platforms deliver superior detection depth and proteome coverage for all sample types. For biomarker identification, algorithms and AI-driven bioinformatic pipelines enable fast, reliable candidate screening. This fully integrated, end-to-end workflow underpins every stage of your biomarker discovery project.

Broad Research Applications of Protein Biomarker Discovery

Protein biomarker discovery uses a large cohort or small sample set to screen differentially expressed protein candidates across study groups, laying a foundation for disease screening, diagnosis and therapeutic monitoring.

1. Cancer Research
