• Assess antibody validation status for each specific application

• Examine differences in sensitivity thresholds between techniques

• Consider post-translational modifications that may affect antibody recognition

• Implement orthogonal non-antibody methods (e.g., mass spectrometry) to resolve conflicts

Differences often reflect the biological reality of protein states rather than experimental errors, particularly when comparing results from methods that detect proteins in different conformational states .

What statistical approaches are recommended for analyzing quantitative SPAC1952.02 antibody binding data?

For robust statistical analysis of antibody binding data:

• Implement technical and biological replicates (minimum n=3 for each)
