Real Curated UBA3 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Testis |
| 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 | PB9838 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 UBA3 Western Blot Band Size?
Use the product-observed 51.9 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 51.9 kDa | Matches the authoritative product WB observation. |
| 51.9 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 UBA3 appearancePlan around 51.9 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 51.9 kDa; use this as the primary experimental expectation. |
| Calculated mass | 51.9 kDa from UniProt Q8TBC4; 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 PB9838. |
| Situation | Likely cause | Next action |
|---|---|---|
| 51.9 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 UBA3 Western blot
🧪Use Testis as the first positive-control candidate and Ovary as the HPA Not detected negative candidate.
Positive control: Testis (High)
Negative control: Ovary (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced UBA3 Western Blot Tips
Deeper troubleshooting and optimisation questions for UBA3, answered from its protein features.
Which band should guide the blot?
Use 51.9 kDa, the observation attached to the authoritative PB9838 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 51.9 kDa expectation.
Which positive control should I start with?
Start with Testis, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Ovary 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 UBA3 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should PB9838 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: PMC4120840, PMC13129363.
