What Is the Expected STIP1 Western Blot Band Size?

Use the product-observed 62.6 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
62.6 kDaMatches the authoritative product WB observation.
62.6 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected STIP1 appearancePlan around 62.6 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band62.6 kDa; use this as the primary experimental expectation.
Calculated mass62.6 kDa from UniProt P31948; retain as context.
Gel selection12-15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with PB9896.
Why is my band missing or off?
SituationLikely causeNext action
62.6 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 STIP1 Western blot

🧪Use Testis as the first positive-control candidate; no defensible HPA Not detected tissue was available, so use a target knockdown/knockout negative control.
Positive control: Testis (High)
Negative control: Target knockdown/knockout
HPA protein score determines control status; other expression data is supporting context only.

Advanced STIP1 Western Blot Tips

Deeper troubleshooting and optimisation questions for STIP1, answered from its protein features.

Which band should guide the blot?
Use 62.6 kDa, the observation attached to the authoritative PB9896 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 62.6 kDa expectation.
Which positive control should I start with?
Start with Testis, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use a target knockdown/knockout control when no HPA Not detected tissue is available.
Which gel should I use?
Use 12-15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for STIP1 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should PB9896 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.
