bio-proteomics-differential-abundance

separate

Statistical testing for differentially abundant proteins between conditions. Covers limma and MSstats workflows with multiple testing correction. Use when identifying proteins with significant abundance changes between experimental groups.

When to use

• identifying proteins with significant abundance changes
• statistical testing on quantified protein intensities
• MSstats groupComparison
• limma eBayes
• scipy.stats.ttest_ind
• proDA differential abundance
• volcano plot visualization

When not to use

• RNA-seq differential expression
• data normalization preparation
