Real Curated CAD Western Blot Protocols
Start with the molecular-weight rule, then compare verified publication-derived conditions.
| Sample / lysate | Appendix |
| Gel % | 4-12% gradient |
| 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 | A00463-1 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 |
Section 2
What Is the Expected CAD Western Blot Band Size?
Use the product-observed 243 kDa band as the primary planning value and retain the UniProt calculated mass as context.
| 243 kDa | Matches the authoritative product WB observation. |
| 243 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 CAD appearancePlan around 243 kDa and keep the calculated mass as supporting context.
| Catalog-observed band | 243 kDa; use this as the primary experimental expectation. |
| Calculated mass | 243 kDa from UniProt P27708; retain as context. |
| Gel selection | 4-12% gradient; shared with the recommended protocol and poster. |
| Specificity check | Compare the lead HPA positive and negative controls with A00463-1. |
| Situation | Likely cause | Next action |
|---|---|---|
| 243 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 CAD Western blot
🧪Use Fallopian tube as the first positive-control candidate and retain an orthogonal negative control.
Positive control: Fallopian tube (High)
Negative control: Heart muscle (Not detected)
HPA protein score determines control status; other expression data is supporting context only.

Advanced CAD Western Blot Tips
Deeper troubleshooting and optimisation questions for CAD, answered from its protein features.
Which band should guide the blot?
Use 243 kDa, the observation attached to the authoritative A00463-1 WB record.
How should calculated mass be interpreted?
Treat the UniProt calculated mass as context; it does not replace the catalog-observed 243 kDa expectation.
Which positive control should I start with?
Start with Fallopian tube, the lead HPA protein-expression candidate.
Which negative control is defensible?
Use Heart muscle as an orthogonal HPA Not detected candidate.
Which gel should I use?
Use 4-12% gradient consistently across the quick facts, protocol table, and poster.
What transfer method to use for CAD Western blot?
Use the transfer method in the recommended protocol and verify transfer before blocking.
How should A00463-1 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.
