EXOSC3 Western Blot Experimental Design Guide
Expected bands, validated protocols, controls and antibodies — the at-a-glance facts below, then the full design guide.
Must know before running
| Expected band | 29.6 kDa | |
| Observed band | Not reported — verify product WB image | |
| Gel | 12-15% | |
| Positive control | Cervix | |
| Negative control | Heart muscle |
Important caveats
Reasons your observed band may differ from the expected size.
| ⓘ | Calculated mass | 29.6 kDa |
| ⓘ | Localization | Cytoplasm / Nucleus, nucleolus |
| ⓘ | Processing / PTM | Record-dependent |
| ⓘ | Reactivity | Human / Mouse |

Real Curated EXOSC3 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Breast |
| Gel % | 12-15% |
| Load | 20-30 µg total protein per lane |
| Transfer | Semi-dry, short transfer |
| Membrane | 0.45 µm PVDF |
| Blocking | 5% non-fat milk or 5% BSA in TBST |
| Primary | A04146-1 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 EXOSC3 Western Blot Band Size?
Use the product-observed 29.6 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 29.6 kDa | Matches the authoritative product WB observation. |
| 29.6 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 EXOSC3 appearancePlan around 29.6 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 29.6 kDa; use this as the primary experimental expectation. |
| Calculated mass | 29.6 kDa from UniProt Q9NQT5; 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 A04146-1. |
| Situation | Likely cause | Next action |
|---|---|---|
| 29.6 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 EXOSC3 Western blot
🧪Use Cervix as the first positive-control candidate and Heart muscle as the HPA Not detected negative candidate.
Positive control: Cervix (High)
Negative control: Heart muscle (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced EXOSC3 Western Blot Tips
Deeper troubleshooting and optimisation questions for EXOSC3, answered from its protein features.
Which band should guide the blot?
Use 29.6 kDa, the observation attached to the authoritative A04146-1 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 29.6 kDa expectation.
Which positive control should I start with?
Start with Cervix, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Heart muscle 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 EXOSC3 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A04146-1 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.
