    3. Apply SnugDock for flexible backbone refinement of antibody-antigen complexes .

  • Validation: Compare computational ΔG binding scores with surface plasmon resonance (SPR) data (e.g., KD improved from 10⁻⁷ M to 10⁻⁹ M) .

• How do I resolve contradictions in At5g63170 subcellular localization studies?

  • Analysis framework:

    Technique	Reported Localization	Potential Artifact
    Confocal (GFP fusion)	Nucleus	Overexpression artifacts
    Immunogold EM	Cytoplasm	Antibody cross-reactivity
    Subcellular fractionation	Mitochondria	Contamination during isolation

Methodological Challenges

• What strategies identify At5g63170 interaction partners without co-purifying contaminants?

  • Workflow:

    1. Perform crosslinking IP-MS with formaldehyde (0.5%, 10 min).

    2. Use At5g63170-KO lines as negative controls for background subtraction .

    3. Apply SAINTexpress scoring (FDR ≤1%) to filter nonspecific interactions .

  • Critical step: Validate hits with reciprocal co-IP and in planta bimolecular fluorescence complementation .

• How to design a longitudinal study tracking At5g63170 expression under stress conditions?

  • Parameters:

    Timepoint	Stressor	Assay
    0–6 hr	Drought	qRT-PCR (primers spanning exon-exon junctions)
    24–48 hr	Pathogen	NanoString (custom probe set)
    7 days	Recovery	Single-cell RNA-seq (10x Genomics)

  • Statistical rigor: Use mixed-effects models to account for plant-to-plant variability .

Technical Notes

• Antibody lot validation: Compare 3 independent lots via ELISA against recombinant At5g63170 (CV <15% acceptable) .

• Epitope mapping: Utilize peptide arrays (15-mer overlaps) to identify linear epitopes; confirm via SPR with alanine mutants .
