ATG14 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 | 55.3 kDa | |
| Observed band | Not reported — verify product WB image | |
| Gel | 12-15% | |
| Positive control | Adipose tissue | |
| Negative control | Target knockdown/knockout |
Important caveats
Reasons your observed band may differ from the expected size.
| ⓘ | Calculated mass | 55.3 kDa |
| ⓘ | Localization | Cytoplasm / Endoplasmic reticulum membrane |
| ⓘ | Processing / PTM | Record-dependent |
| ⓘ | Reactivity | Human / Rat |
Sample controls for ATG14 Western blot
🧪Use Adipose tissue as the first positive-control candidate; no defensible HPA Not detected tissue was available, so use a target knockdown/knockout negative control.
Positive control: Adipose tissue (Medium)
Negative control: Target knockdown/knockout
HPA protein score determines control status; other expression data is supporting context only.

Positive expression · recommended positive controls
| Tissue | Cell type | Level | Evidence | Source |
|---|---|---|---|---|
| Adipose tissue | Reported tissue cells | Medium | Protein (HPA) | HPA → |
| Breast | Reported tissue cells | Medium | Protein (HPA) | HPA → |
| Adrenal gland | Reported tissue cells | Medium | Protein (HPA) | HPA → |
| Appendix | Reported tissue cells | Medium | Protein (HPA) | HPA → |
Undetected expression · recommended negative controls
| Tissue | Cell type | Level | Evidence | Source |

No HPA Not detected tissue is available; use a target knockdown/knockout negative control.
Section 1
What Is the Expected ATG14 Western Blot Band Size?
Use the product-observed 55.3 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 55.3 kDa | Matches the authoritative product WB observation. |
| 55.3 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 ATG14 appearancePlan around 55.3 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 55.3 kDa; use this as the primary experimental expectation. |
| Calculated mass | 55.3 kDa from UniProt Q6ZNE5; 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 PB9481. |
| Situation | Likely cause | Next action |
|---|---|---|
| 55.3 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 ATG14 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 | PB9481 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 ATG14 Western Blot Tips
Deeper troubleshooting and optimisation questions for ATG14, answered from its protein features.
Which band should guide the blot?
Use 55.3 kDa, the observation attached to the authoritative PB9481 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 55.3 kDa expectation.
Which positive control should I start with?
Start with Adipose tissue, 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 ATG14 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should PB9481 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: PMC8686392, PMC10591826.
