ARSA 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 | 53.6 kDa observed | |
| Observed band | 53.6 kDa observed | |
| Gel | 12-15% | |
| Positive control | Cerebellum | |
| Negative control | Use knockout/knockdown or orthogonal negative |
Important caveats
Reasons your observed band may differ from the expected size.
| ⓘ | Calculated mass | 53.6 kDa |
| ⓘ | Localization | Endoplasmic reticulum / Lysosome |
| ⓘ | Processing / PTM | Record-dependent |
| ⓘ | Reactivity | Human / Mouse / Rat |

Real Curated ARSA Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Adrenal gland |
| 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 | M02583 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 ARSA Western Blot Band Size?
Use the product-observed 53.6 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 53.6 kDa | Matches the authoritative product WB observation. |
| 53.6 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 ARSA appearancePlan around 53.6 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 53.6 kDa; use this as the primary experimental expectation. |
| Calculated mass | 53.6 kDa from UniProt P15289; 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 M02583. |
| Situation | Likely cause | Next action |
|---|---|---|
| 53.6 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 ARSA Western blot
🧪Use Cerebellum as the first positive-control candidate and retain an orthogonal negative control.
Positive control: Cerebellum (High)
HPA protein score determines control status; other expression data is supporting context only.

Positive expression · recommended positive controls
| Tissue | Cell type | Level | Evidence | Source |
|---|---|---|---|---|
| Cerebellum | Reported tissue cells | High | Protein (HPA) | HPA → |
| Gallbladder | Reported tissue cells | High | Protein (HPA) | HPA → |
| Colon | Reported tissue cells | High | Protein (HPA) | HPA → |
| Adrenal gland | Reported tissue cells | High | Protein (HPA) | HPA → |
| Bone marrow | Reported tissue cells | Low | Protein (HPA) | HPA → |
| Oral mucosa | Reported tissue cells | Low | Protein (HPA) | HPA → |
Undetected expression · recommended negative controls
The available HPA profile lists no reliably-negative tissue for ARSA (a broadly-expressed target). Use a ARSA knockdown (siRNA/shRNA) or knockout lysate as the negative control and confirm signal loss versus the parental lysate.

Advanced ARSA Western Blot Tips
Deeper troubleshooting and optimisation questions for ARSA, answered from its protein features.
Which band should guide the blot?
Use 53.6 kDa, the observation attached to the authoritative M02583 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 53.6 kDa expectation.
Which positive control should I start with?
Start with Cerebellum, 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 ARSA Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should M02583 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.
