What Is the Expected IGF1R Western Blot Band Size?

Use the product-observed 154.8 kDa band as the primary planning value and retain the UniProt calculated mass as context.

What am I looking at on my blot?
154.8 kDaMatches the authoritative product WB observation.
154.8 kDa calculatedUse as UniProt context, not as a replacement observed band.
Unexpected additional signalDo not assign identity without orthogonal positive/negative controls.
💡Expected IGF1R appearancePlan around 154.8 kDa and keep the calculated mass as supporting context.
How each factor affects band size
Catalog-observed band154.8 kDa; use this as the primary experimental expectation.
Calculated mass154.8 kDa from UniProt P08069; retain as context.
Gel selection8-10%; shared with the recommended protocol and poster.
Specificity checkCompare the lead HPA positive and negative controls with A00070-3.
Why is my band missing or off?
SituationLikely causeNext action
154.8 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 IGF1R Western blot

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

Undetected expression · recommended negative controls

The available HPA profile lists no reliably-negative tissue for IGF1R (a broadly-expressed target). Use a IGF1R knockdown (siRNA/shRNA) or knockout lysate as the negative control and confirm signal loss versus the parental lysate.

Advanced IGF1R Western Blot Tips

Deeper troubleshooting and optimisation questions for IGF1R, answered from its protein features.

Which band should guide the blot?
Use 154.8 kDa, the observation attached to the authoritative A00070-3 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 154.8 kDa expectation.
Which positive control should I start with?
Start with Adrenal gland, 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 8-10% consistently across the quick facts, protocol table, and poster.
What transfer method to use for IGF1R Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A00070-3 be started?
Start at the linked datasheet condition and run a three-point primary-antibody dilution test.
Which publication-derived protocols can I compare?
No verified publication protocol was supplied; use only the deterministic recommended protocol.
