What Is the Expected JUP Western Blot Band Size?

Use the product-observed 81.7 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
81.7 kDaMatches the authoritative product WB observation.
81.7 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected JUP appearancePlan around 81.7 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band81.7 kDa; use this as the primary experimental expectation.
Calculated mass81.7 kDa from UniProt P14923; retain as context.
Gel selection8-10%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with M01901-3.
Why is my band missing or off?
SituationLikely causeNext action
81.7 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 JUP Western blot

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

Advanced JUP Western Blot Tips

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

Which band should guide the blot?
Use 81.7 kDa, the observation attached to the authoritative M01901-3 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 81.7 kDa expectation.
Which positive control should I start with?
Start with Breast, 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 8-10% consistently across the quick facts, protocol table, and poster.
What transfer method to use for JUP Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should M01901-3 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.
