What Is the Expected HCCS Western Blot Band Size?

Use the product-observed 30.6 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
30.6 kDaMatches the authoritative product WB observation.
30.6 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected HCCS appearancePlan around 30.6 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band30.6 kDa; use this as the primary experimental expectation.
Calculated mass30.6 kDa from UniProt P53701; retain as context.
Gel selection12-15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A00924-2.
Why is my band missing or off?
SituationLikely causeNext action
30.6 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 HCCS Western blot

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

Advanced HCCS Western Blot Tips

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

Which band should guide the blot?
Use 30.6 kDa, the observation attached to the authoritative A00924-2 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 30.6 kDa expectation.
Which positive control should I start with?
Start with Parathyroid gland, 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 12-15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for HCCS Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A00924-2 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.
