What Is the Expected TKT Western Blot Band Size?

Use the product-observed 67.9 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
67.9 kDaMatches the authoritative product WB observation.
67.9 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected TKT appearancePlan around 67.9 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band67.9 kDa; use this as the primary experimental expectation.
Calculated mass67.9 kDa from UniProt P29401; retain as context.
Gel selection12-15%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A02197-1.
Why is my band missing or off?
SituationLikely causeNext action
67.9 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 TKT Western blot

🧪Use Esophagus as the first positive-control candidate and retain an orthogonal negative control.
Positive control: Esophagus (High)
HPA protein score determines control status; other expression data is supporting context only.

Advanced TKT Western Blot Tips

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

Which band should guide the blot?
Use 67.9 kDa, the observation attached to the authoritative A02197-1 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 67.9 kDa expectation.
Which positive control should I start with?
Start with Esophagus, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use a target knockdown/knockout control when no HPA Not detected tissue is available.
Which gel should I use?
Use 12-15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for TKT Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A02197-1 be started?
Start at the linked datasheet condition and run a three-point primary-antibody dilution test.
Which publication-derived protocols can I compare?
No verified publication protocol was supplied; use only the deterministic recommended protocol.
