Microprotein Reproducibility Crisis and Path to Clinical Translation: Integration of Benchmarking, Immunopeptidomics, and Regulatory Hurdles

Spotlight 2026-05-27 09:00 UTC

Microprotein discovery faces a reproducibility crisis with only 3.5% of peptides replicable across studies, yet immunopeptidomics achieves 65% high-confidence detection vs 7.8% for conventional proteomics, necessitating urgent standardization, orthogonal validation via targeted metabolomics, and regulatory clarity before commercial diagnostics can advance.
