Perform orthogonal validation using CRISPR-Cas9 knockout (KO) cell lines as negative controls in Western blotting and immunofluorescence .
Combine multiple techniques:
Epitope analysis: Map antibody binding regions using peptide arrays
Post-translational modification (PTM) assessment: Compare results from:
Quantitative correlation: Calculate Pearson’s r between IF intensity and WB band density across 10+ biological replicates
Integrate multi-omics data:
Implement:
