PCK1 Western Blot Experimental Design Guide
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 | 69.2 kDa | |
| Observed band | Not reported — verify product WB image | |
| Gel | 12-15% | |
| Positive control | Kidney | |
| Negative control | Bone marrow |
Important caveats
Reasons your observed band may differ from the expected size.
| ⓘ | Calculated mass | 69.2 kDa |
| ⓘ | Localization | Cytoplasm, cytosol / Endoplasmic reticulum |
| ⓘ | Processing / PTM | Record-dependent |
| ⓘ | Reactivity | Human / Mouse / Rat |
Section 1
Real Curated PCK1 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Kidney |
| 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 | A02022-3 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 PCK1 Western Blot Band Size?
Use the product-observed 69.2 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 69.2 kDa | Matches the authoritative product WB observation. |
| 69.2 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 PCK1 appearancePlan around 69.2 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 69.2 kDa; use this as the primary experimental expectation. |
| Calculated mass | 69.2 kDa from UniProt P35558; 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 A02022-3. |
| Situation | Likely cause | Next action |
|---|---|---|
| 69.2 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 PCK1 Western blot
🧪Use Kidney as the first positive-control candidate and Bone marrow as the HPA Not detected negative candidate.
Positive control: Kidney (High)
Negative control: Bone marrow (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced PCK1 Western Blot Tips
Deeper troubleshooting and optimisation questions for PCK1, answered from its protein features.
Which band should guide the blot?
Use 69.2 kDa, the observation attached to the authoritative A02022-3 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 69.2 kDa expectation.
Which positive control should I start with?
Start with Kidney, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Bone marrow 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 PCK1 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A02022-3 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: PMC7948413, PMC7125947, PMC8677624.
