What Is the Expected TOMM70 Western Blot Band Size?

Use the product-observed 67.5 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
67.5 kDaMatches the authoritative product WB observation.
67.5 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected TOMM70 appearancePlan around 67.5 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band67.5 kDa; use this as the primary experimental expectation.
Calculated mass67.5 kDa from UniProt O94826; retain as context.
Gel selection12-15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A09172-2.
Why is my band missing or off?
SituationLikely causeNext action
67.5 kDaMatches the authoritative product WB observation.Confirm with orthogonal controls and the linked product record.
Additional bandMay reflect processing, modification, or non-specific signal.Run a dilution series and compare positive/negative controls.
Weak signalTarget abundance or transfer may be limiting.Verify transfer, increase positive-control abundance, and bracket exposure.

Sample controls for TOMM70 Western blot

🧪Use Caudate as the first positive-control candidate and Lymph node as the HPA Not detected negative candidate.
Positive control: Caudate (High)
Negative control: Lymph node (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced TOMM70 Western Blot Tips

Deeper troubleshooting and optimisation questions for TOMM70, answered from its protein features.

Which band should guide the blot?
Use 67.5 kDa, the observation attached to the authoritative A09172-2 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 67.5 kDa expectation.
Which positive control should I start with?
Start with Caudate, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Lymph node as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 12-15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for TOMM70 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A09172-2 be started?
Start at the linked datasheet condition and run a three-point primary-antibody dilution test.
Which publication-derived protocols can I compare?
No verified publication protocol was supplied; use only the deterministic recommended protocol.
