Sample controls for AASS Western blot

🧪Use Lung as the first positive-control candidate and Soft tissue as the HPA Not detected negative candidate.

Positive control: Lung (High)

Negative control: Soft tissue (Not detected)

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

Section 1

What Is the Expected AASS Western Blot Band Size?

Use the product-observed 102.1 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
102.1 kDa	Matches the authoritative product WB observation.
102.1 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 AASS appearancePlan around 102.1 kDa and keep the calculated mass as supporting context.

How each factor affects band size
Catalog-observed band	102.1 kDa; use this as the primary experimental expectation.
Calculated mass	102.1 kDa from UniProt Q9UDR5; 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 A07302-3.

Why is my band missing or off?
Situation	Likely cause	Next action
102.1 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.

Advanced AASS Western Blot Tips

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

Which band should guide the blot?

Use 102.1 kDa, the observation attached to the authoritative A07302-3 WB record.

How should calculated mass be interpreted?

Treat the UniProt calculated mass as context; it does not replace the catalog-observed 102.1 kDa expectation.

Which positive control should I start with?

Start with Lung, the lead HPA protein-expression candidate.

Which negative control is defensible?

Use Soft tissue 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 AASS Western blot?

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

How should A07302-3 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: PMC12554910, PMC10676743, PMC6363459.
