Real Curated HSPB2 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Heart muscle |
| 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 | PA1802 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 HSPB2 Western Blot Band Size?
Use the product-observed 20.2 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 20.2 kDa | Matches the authoritative product WB observation. |
| 20.2 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 HSPB2 appearancePlan around 20.2 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 20.2 kDa; use this as the primary experimental expectation. |
| Calculated mass | 20.2 kDa from UniProt Q16082; 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 PA1802. |
| Situation | Likely cause | Next action |
|---|---|---|
| 20.2 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 HSPB2 Western blot
🧪Use Kidney as the first positive-control candidate and retain an orthogonal negative control.
Positive control: Kidney (Medium)
Negative control: Appendix (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced HSPB2 Western Blot Tips
Deeper troubleshooting and optimisation questions for HSPB2, answered from its protein features.
Which band should guide the blot?
Use 20.2 kDa, the observation attached to the authoritative PA1802 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 20.2 kDa expectation.
Which positive control should I start with?
Start with Kidney, 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 HSPB2 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should PA1802 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.
