What Is the Expected RPGR Western Blot Band Size?

Use the product-observed 113.4 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
113.4 kDaMatches the authoritative product WB observation.
113.4 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected RPGR appearancePlan around 113.4 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band113.4 kDa; use this as the primary experimental expectation.
Calculated mass113.4 kDa from UniProt Q92834; retain as context.
Gel selection8-10%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A01522.
Why is my band missing or off?
SituationLikely causeNext action
113.4 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 RPGR Western blot

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

Advanced RPGR Western Blot Tips

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

Which band should guide the blot?
Use 113.4 kDa, the observation attached to the authoritative A01522 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 113.4 kDa expectation.
Which positive control should I start with?
Start with Fallopian tube, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Bone marrow 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 RPGR Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A01522 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.
