ELOB 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 | 13.1 kDa | |
| Observed band | Not reported — verify product WB image | |
| Gel | 15% | |
| Positive control | Cervix | |
| Negative control | Soft tissue |
Important caveats
Reasons your observed band may differ from the expected size.
| ⓘ | Calculated mass | 13.1 kDa |
| ⓘ | Localization | Nucleus |
| ⓘ | Processing / PTM | Record-dependent |
| ⓘ | Reactivity | Human / Mouse / Rat |
Sample controls for ELOB Western blot
🧪Use Cervix as the first positive-control candidate and Soft tissue as the HPA Not detected negative candidate.
Positive control: Cervix (High)
Negative control: Soft tissue (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Section 1
What Is the Expected ELOB Western Blot Band Size?
Use the product-observed 13.1 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 13.1 kDa | Matches the authoritative product WB observation. |
| 13.1 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 ELOB appearancePlan around 13.1 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 13.1 kDa; use this as the primary experimental expectation. |
| Calculated mass | 13.1 kDa from UniProt Q15370; retain as context. |
| Gel selection | 15%; shared with the recommended protocol and poster. |
| Specificity check | Compare the lead HPA positive and negative controls with A31718-2. |
| Situation | Likely cause | Next action |
|---|---|---|
| 13.1 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. |

Real Curated ELOB Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Adrenal gland |
| Gel % | 15% |
| Load | 20-30 µg total protein per lane |
| Transfer | Semi-dry, short transfer |
| Membrane | 0.2 µm PVDF |
| Blocking | 5% non-fat milk or 5% BSA in TBST |
| Primary | A31718-2 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 |

Advanced ELOB Western Blot Tips
Deeper troubleshooting and optimisation questions for ELOB, answered from its protein features.
Which band should guide the blot?
Use 13.1 kDa, the observation attached to the authoritative A31718-2 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 13.1 kDa expectation.
Which positive control should I start with?
Start with Cervix, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Soft tissue as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 15% consistently across the quick facts, protocol table, and poster.
What transfer method to use for ELOB Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A31718-2 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: PMC11039524, PMC4265484.
