Common Challenges We Help Address

• Complex endogenous matrix interference in aquatic tissues masks low-abundance functional proteins, leading to omission of key stress and disease-related biomarkers.
• Unreasonable selection of quantitative technologies causes inconsistent data repeatability and inaccurate differential protein quantification in multi-sample comparative experiments.
• Most conventional analytical methods only focus on protein expression levels, ignoring post-translational modifications that dominate aquatic physiological phenotypic changes.
• Lack of scenario-based standardized schemes for aquatic food identification and environmental pollution biomarker screening, resulting in poor industrial conversion of research data.
• Complicated original mass spectral data cannot be efficiently correlated with aquatic physiological phenotypes and environmental change characteristics.
