What Is the Expected RNF43 Western Blot Band Size?

Use the product-observed 85.7 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
85.7 kDa	Matches the authoritative product WB observation.
85.7 kDa calculated	Use as UniProt context, not as a replacement observed band.
Unexpected additional signal	Do not assign identity without orthogonal positive/negative controls.

💡Expected RNF43 appearancePlan around 85.7 kDa and keep the calculated mass as supporting context.

How each factor affects band size
Catalog-observed band	85.7 kDa; use this as the primary experimental expectation.
Calculated mass	85.7 kDa from UniProt Q68DV7; retain as context.
Gel selection	8-10%; shared with the recommended protocol and poster.
Specificity check	Compare the lead HPA positive and negative controls with A01694-1.

Why is my band missing or off?
Situation	Likely cause	Next action
85.7 kDa	Matches the authoritative product WB observation.	Confirm with orthogonal controls and the linked product record.
Additional band	May reflect processing, modification, or non-specific signal.	Run a dilution series and compare positive/negative controls.
Weak signal	Target abundance or transfer may be limiting.	Verify transfer, increase positive-control abundance, and bracket exposure.

Sample controls for RNF43 Western blot

🧪Use Adrenal gland as the first positive-control candidate and Oral mucosa as the HPA Not detected negative candidate.

Positive control: Adrenal gland (High)

Negative control: Oral mucosa (Not detected)

HPA protein score determines control status; other expression data is supporting context only.

Advanced RNF43 Western Blot Tips

Deeper troubleshooting and optimisation questions for RNF43, answered from its protein features.

Which band should guide the blot?

Use 85.7 kDa, the observation attached to the authoritative A01694-1 WB record.

How should calculated mass be interpreted?

Treat the UniProt calculated mass as context; it does not replace the catalog-observed 85.7 kDa expectation.

Which positive control should I start with?

Start with Adrenal gland, the lead HPA protein-expression candidate.

Which negative control is defensible?

Use Oral mucosa 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 RNF43 Western blot?

Use the transfer method in the recommended protocol and verify transfer before blocking.

How should A01694-1 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: PMC5406878, PMC10079101, PMC7503102.
