What Is the Expected PSAT1 Western Blot Band Size?

Use the product-observed 40.4 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
40.4 kDaMatches the authoritative product WB observation.
40.4 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected PSAT1 appearancePlan around 40.4 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band40.4 kDa; use this as the primary experimental expectation.
Calculated mass40.4 kDa from UniProt Q9Y617; retain as context.
Gel selection12-15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A06277.
Why is my band missing or off?
SituationLikely causeNext action
40.4 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 PSAT1 Western blot

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

Advanced PSAT1 Western Blot Tips

Deeper troubleshooting and optimisation questions for PSAT1, answered from its protein features.

Which band should guide the blot?
Use 40.4 kDa, the observation attached to the authoritative A06277 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 40.4 kDa expectation.
Which positive control should I start with?
Start with Kidney, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Appendix 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 PSAT1 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A06277 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.
