What Is the Expected ELOB Western Blot Band Size?

Use the product-observed 13.1 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
13.1 kDaMatches the authoritative product WB observation.
13.1 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected ELOB appearancePlan around 13.1 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band13.1 kDa; use this as the primary experimental expectation.
Calculated mass13.1 kDa from UniProt Q15370; retain as context.
Gel selection15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A31718-2.
Why is my band missing or off?
SituationLikely causeNext action
13.1 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 ELOB Western blot

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

Advanced ELOB Western Blot Tips

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

Which band should guide the blot?
Use 13.1 kDa, the observation attached to the authoritative A31718-2 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 13.1 kDa expectation.
Which positive control should I start with?
Start with Cervix, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Soft tissue as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for ELOB Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A31718-2 be started?
Start at the linked datasheet condition and run a three-point primary-antibody dilution test.
Which publication-derived protocols can I compare?
Compare only the supplied target-verified records: PMC11039524, PMC4265484.
