Sample controls for BCAM Western blot

🧪Use Kidney as the first positive-control candidate and Cerebral cortex as the HPA Not detected negative candidate.

Positive control: Kidney (High)

Negative control: Cerebral cortex (Not detected)

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

Section 1

What Is the Expected BCAM Western Blot Band Size?

Use the product-observed 67.4 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
67.4 kDa	Matches the authoritative product WB observation.
67.4 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 BCAM appearancePlan around 67.4 kDa and keep the calculated mass as supporting context.

How each factor affects band size
Catalog-observed band	67.4 kDa; use this as the primary experimental expectation.
Calculated mass	67.4 kDa from UniProt P50895; retain as context.
Gel selection	12-15%; shared with the recommended protocol and poster.
Specificity check	Compare the lead HPA positive and negative controls with A03148-1.

Why is my band missing or off?
Situation	Likely cause	Next action
67.4 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 BCAM Western Blot Tips

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

Which band should guide the blot?

Use 67.4 kDa, the observation attached to the authoritative A03148-1 WB record.

How should calculated mass be interpreted?

Treat the UniProt calculated mass as context; it does not replace the catalog-observed 67.4 kDa expectation.

Which positive control should I start with?

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

Which negative control is defensible?

Use Cerebral cortex 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 BCAM Western blot?

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

How should A03148-1 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: PMC7138403, PMC13120982.
