What Is the Expected SULT2A1 Western Blot Band Size?

Use the product-observed 33.8 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
33.8 kDaMatches the authoritative product WB observation.
33.8 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected SULT2A1 appearancePlan around 33.8 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band33.8 kDa; use this as the primary experimental expectation.
Calculated mass33.8 kDa from UniProt Q06520; retain as context.
Gel selection12-15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with PB9821.
Why is my band missing or off?
SituationLikely causeNext action
33.8 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 SULT2A1 Western blot

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

Advanced SULT2A1 Western Blot Tips

Deeper troubleshooting and optimisation questions for SULT2A1, answered from its protein features.

Which band should guide the blot?
Use 33.8 kDa, the observation attached to the authoritative PB9821 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 33.8 kDa expectation.
Which positive control should I start with?
Start with Liver, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Adipose tissue as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 12-15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for SULT2A1 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should PB9821 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.
