PAX8 Western Blot Experimental Design Guide
Expected bands, documented protocol parameters, controls and antibodies — the at-a-glance facts below, then the full design guide.
Must know before running
| Expected band | 48.2 kDa | |
| Observed band | Not reported — verify product WB image | |
| Gel | 12-15% | |
| Positive control | Thyroid gland | |
| Negative control | Appendix |
Important caveats
Reasons your observed band may differ from the expected size.

Real Curated PAX8 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Endometrium |
| Gel % | 12-15% |
| Load | 20-30 µg total protein per lane |
| Transfer | Semi-dry, standard transfer |
| Membrane | 0.45 µm PVDF |
| Blocking | 5% non-fat milk or 5% BSA in TBST |
| Primary | A00943-1 at datasheet starting dilution |
| Primary incubation | Overnight at 4 °C with gentle agitation |
| Secondary | Species-matched HRP conjugate at validated dilution |
| Wash | 3 × 5 min in TBST |
| Detection | Chemiluminescent substrate |
| Exposure | Bracket exposures to avoid saturation |

What Is the Expected PAX8 Western Blot Band Size?
Use the product-observed 48.2 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 48.2 kDa | Matches the authoritative product WB observation. |
| 48.2 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 PAX8 appearancePlan around 48.2 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 48.2 kDa; use this as the primary experimental expectation. |
| Calculated mass | 48.2 kDa from UniProt Q06710; 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 A00943-1. |
| Situation | Likely cause | Next action |
|---|---|---|
| 48.2 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. |

Sample controls for PAX8 Western blot
🧪Use Thyroid gland as the first positive-control candidate and Appendix as the HPA Not detected negative candidate.
Positive control: Thyroid gland (High)
Negative control: Appendix (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced PAX8 Western Blot Tips
Deeper troubleshooting and optimisation questions for PAX8, answered from its protein features.
Which band should guide the blot?
Use 48.2 kDa, the observation attached to the authoritative A00943-1 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 48.2 kDa expectation.
Which positive control should I start with?
Start with Thyroid gland, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Appendix 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 PAX8 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A00943-1 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.
