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 | 38.7 kDa | |

| Gel | 12-15% | |
| Positive control | Breast | |
| Negative control | Target knockdown/knockout |
Important caveats
Reasons your observed band may differ from the expected size.

Real Curated HNRNPA1 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Adipose tissue |
| 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 | A01476 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 HNRNPA1 Western Blot Band Size?
Use the product-observed 38.7 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 38.7 kDa | Matches the authoritative product WB observation. |
| 38.7 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 HNRNPA1 appearancePlan around 38.7 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 38.7 kDa; use this as the primary experimental expectation. |
| Calculated mass | 38.7 kDa from UniProt P09651; 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 A01476. |
| Situation | Likely cause | Next action |
|---|---|---|
| 38.7 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 HNRNPA1 Western blot
🧪Use Breast as the first positive-control candidate; no defensible HPA Not detected tissue was available, so use a target knockdown/knockout negative control.
Positive control: Breast (High)
Negative control: Target knockdown/knockout
HPA protein score determines control status; other expression data is supporting context only.

Advanced HNRNPA1 Western Blot Tips
Deeper troubleshooting and optimisation questions for HNRNPA1, answered from its protein features.
Which band should guide the blot?
Use 38.7 kDa, the observation attached to the authoritative A01476 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 38.7 kDa expectation.
Which positive control should I start with?
Start with Breast, 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 12-15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for HNRNPA1 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A01476 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.
