What Is the Expected TEAD4 Western Blot Band Size?

TEAD4 is predicted at 48.3 kDa; three isoforms could affect migration, but no empirical band or distinct isoform pattern is supplied.

What am I looking at on my blot?
Band near 48.3 kDaConsistent with the predicted TEAD4 mass; confirm identity with controls
Several bands near the expected regionTEAD4 has three named isoforms, but their migration is unknown
One band despite three isoformsThe isoforms are not known to resolve into distinct bands
Weak or absent band in a cytoplasmic fractionTEAD4 is annotated as nuclear
💡Expected TEAD4 appearanceTEAD4 has a predicted mass of 48.3 kDa, but no empirical band size is supplied; use an appropriate positive control and TEAD4 depletion to assess band identity.
How each factor affects band size
Predicted TEAD4 massSets a reference of 48.3 kDa, not a validated migration position
Isoform 1Its individual mass and migration are not supplied
Isoform 2Alternative splicing may affect size, but its individual mass and migration are not supplied
Isoform 3Alternative splicing may affect size, but its individual mass and migration are not supplied
Why is my band missing or off?

Sample controls for TEAD4 Western blot

🧪HPA-IHC candidate guidance (verify in WB): For positive controls for TEAD4 in Western blot, you can use appendix tissue, which HPA rates as medium for TEAD4.
Positive control: Appendix (IHC candidate; verify WB)
Negative control: Adipose tissue (IHC candidate; verify WB)
Loading controls: Run GAPDH, β-actin, and a total-protein stain such as Ponceau alongside the samples.
⚠️Feasibility: TEAD4 is nuclear, so nuclear-enriched lysate may improve detection; HPA identifies adipose tissue as not detected.

Advanced TEAD4 Western Blot Tips

Deeper troubleshooting and optimisation questions for TEAD4, answered from its protein features.

How should TEAD4 band migration be interpreted?
Band shift · Use the separately labelled calculated mass and catalog-observed evidence above. A sequence annotation does not establish an observed migration shift. Verify target identity with orthogonal controls.
Could TEAD4 isoforms produce different bands?
Isoforms · Three isoforms are listed. In UniProt coordinates, isoform 2 lacks residues 1–129 and isoform 3 lacks residues 119–161. These sequence differences could affect band size, but the features do not establish where either isoform migrates.

Check the antibody’s binding region against the listed deletions. An antibody requiring UniProt residues 1–129 may miss isoform 2; one requiring residues 119–161 may miss isoform 3. Confirm the antibody’s numbering convention before comparing coordinates.
Can an annotated modification explain a TEAD4 band shift?
PTM · This record lists no modified residues or glycosylation sites. Do not assign a shifted band to a specific modification from these features. A predicted mass alone also cannot establish the cause of a migration difference.
Does this guide establish induction of TEAD4?
Induction · No general induction response is established by this guide. A pathway or gene-set association is not evidence of induction in a particular specimen. Verify the relevant treatment and control in a target-specific experiment.
How should transfer be checked for TEAD4?
Transfer · Standard workflow guidance: verify transfer efficiency for the intended target size before interpreting a weak signal. Use total-protein assessment and optimize transfer for the membrane, gel and apparatus; the labelled catalog values take precedence.
How should blocking be optimized?
Blocking · Standard workflow guidance: follow the A04289-1 datasheet where specified. Otherwise compare 5% milk or 5% BSA in TBST; for a phospho-specific assay start with BSA. Optimize background and specific signal with matched controls.
How should TEAD4 be quantified?
Quantitation · Standard workflow guidance: quantify only a validated target band within the linear exposure range. Use consistent sample preparation and loading, retain biological replicates, and avoid interpreting saturation or loading differences as regulation.
What size band should I expect for TEAD4?
Interpretation · The canonical TEAD4 sequence is 434 residues with a predicted mass of 48.3 kDa. No observed band position is supplied, so use 48.3 kDa as a reference, not a guaranteed migration position.

Compare its position with the 48.3 kDa canonical prediction, then check whether the antibody can detect isoforms 2 and 3. The listed deletions make isoforms worth considering, but these features alone cannot identify an unexpected band.

TEAD4 is listed as nuclear and has three isoforms. Use a consistent sample preparation and decide whether the measurement concerns one band or the combined TEAD4 signal. Keep that choice consistent across samples.
