LIG3 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 | 112.9 kDa | |
| Observed band | Not reported — verify product WB image | |
| Gel | 8-10% | |
| Positive control | Cerebellum | |
| Negative control | Smooth muscle |
Important caveats
Reasons your observed band may differ from the expected size.

| ⓘ | Localization | Mitochondrion / Mitochondrion |
| ⓘ | Processing / PTM | Record-dependent |
| ⓘ | Reactivity | Human / Mouse / Rat |
Sample controls for LIG3 Western blot
🧪Use Cerebellum as the first positive-control candidate and Smooth muscle as the HPA Not detected negative candidate.
Positive control: Cerebellum (High)
Negative control: Smooth muscle (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

|---|---|---|---|---|
| Cerebellum | Reported tissue cells | High | Protein (HPA) | HPA → |
| Breast | Reported tissue cells | High | Protein (HPA) | HPA → |

Section 1
What Is the Expected LIG3 Western Blot Band Size?
Use the product-observed 112.9 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 112.9 kDa | Matches the authoritative product WB observation. |
| 112.9 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 LIG3 appearancePlan around 112.9 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 112.9 kDa; use this as the primary experimental expectation. |
| Calculated mass | 112.9 kDa from UniProt P49916; retain as context. |
| Gel selection | 8-10%; shared with the recommended protocol and poster. |
| Specificity check | Compare the lead HPA positive and negative controls with A02741-2. |
| Situation | Likely cause | Next action |
|---|---|---|
| 112.9 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 LIG3 Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Bone marrow |
| Gel % | 8-10% |
| Load | 20-30 µg total protein per lane |
| Transfer | Wet/tank, extended transfer |
| Membrane | 0.45 µm PVDF |
| Blocking | 5% non-fat milk or 5% BSA in TBST |
| Primary | A02741-2 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 LIG3 Western Blot Tips
Deeper troubleshooting and optimisation questions for LIG3, answered from its protein features.
Which band should guide the blot?
Use 112.9 kDa, the observation attached to the authoritative A02741-2 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 112.9 kDa expectation.
Which positive control should I start with?
Start with Cerebellum, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Smooth muscle as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 8-10% consistently across the quick facts, protocol table, and poster.
What transfer method to use for LIG3 Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A02741-2 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: PMC10363431, PMC6365379, PMC8241731.
