Real Curated MUC5AC Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Bronchus |
| Gel % | 4-12% gradient |
| Load | 20-30 µg total protein per lane |
| Transfer | Wet/tank, extended transfer |
| Membrane | 0.45 µm PVDF |
| Blocking | 5% non-fat milk or 5% BSA in TBST |
| Primary | PA2303 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 MUC5AC Western Blot Band Size?
Use the product-observed 585.6 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 585.6 kDa | Matches the authoritative product WB observation. |
| 585.6 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 MUC5AC appearancePlan around 585.6 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 585.6 kDa; use this as the primary experimental expectation. |
| Calculated mass | 585.6 kDa from UniProt P98088; retain as context. |
| Gel selection | 4-12% gradient; shared with the recommended protocol and poster. |
| Specificity check | Compare the lead HPA positive and negative controls with PA2303. |
| Situation | Likely cause | Next action |
|---|---|---|
| 585.6 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 MUC5AC Western blot
🧪Use Stomach as the first positive-control candidate and Adipose tissue as the HPA Not detected negative candidate.
Positive control: Stomach (High)
Negative control: Adipose tissue (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced MUC5AC Western Blot Tips
Deeper troubleshooting and optimisation questions for MUC5AC, answered from its protein features.
Which band should guide the blot?
Use 585.6 kDa, the observation attached to the authoritative PA2303 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 585.6 kDa expectation.
Which positive control should I start with?
Start with Stomach, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Adipose tissue as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 4-12% gradient consistently across the quick facts, protocol table, and poster.
What transfer method to use for MUC5AC Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should PA2303 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.
