What Is the Expected DMRTA2 Western Blot Band Size?

DMRTA2 is predicted at 53.4 kDa; nuclear localization may affect recovery, but the supplied features do not demonstrate a migration shift.

What am I looking at on my blot?
Band near 53.4 kDaConsistent with the predicted size of full-length DMRTA2; confirm identity with controls.
Band near 53.4 kDa enriched in nuclear fractionConsistent with DMRTA2 nuclear localization.
Weak band near 53.4 kDa in whole-cell lysateNuclear fractionation may improve detection of DMRTA2.
Additional bands away from 53.4 kDaTheir identity is not established by the supplied features.
💡Expected DMRTA2 appearanceFull-length DMRTA2 has a predicted mass of 53.4 kDa; no empirical band size is supplied, so confirm any candidate band with ordinary identity controls.
How each factor affects band size
UniProt predicted molecular weightSets a 53.4 kDa reference for full-length DMRTA2.
Full-length 542-residue sequenceDefines the polypeptide represented by the predicted mass.
Calculated mass of 53,356 DaExpresses the same predicted mass more precisely, without establishing gel migration.
Full-length mass referenceDoes not establish a separate mature or cleaved band size.

Sample controls for DMRTA2 Western blot

🧪For positive controls for DMRTA2 in Western blot, you can use an independently validated DMRTA2-expressing sample; no HPA positive tissue or cell is supplied.
Positive control: No high/medium HPA tissue identified
Negative control: Suggested KO / knockdown lysate
Loading controls: Run GAPDH, β-actin, and a total-protein stain alongside the samples.
⚠️Feasibility: HPA provides no expression data, so suitable positive and negative samples require independent validation.

Advanced DMRTA2 Western Blot Tips

Deeper troubleshooting and optimisation questions for DMRTA2, answered from its protein features.

How should DMRTA2 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 DMRTA2 isoforms produce multiple bands?
Isoforms · The supplied record lists one isoform and no alternative sequence. It does not provide an isoform-based explanation for multiple bands.
Do annotated modifications prove a band shift?
PTM · The linked UniProt record describes protein features. A modification annotation alone does not demonstrate a visible shift; retain any condition or experimental qualifier attached to it.
Does this guide establish induction of DMRTA2?
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 DMRTA2?
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 A13203 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 DMRTA2 bands be quantified across samples?
Quantitation · Compare the same candidate band across consistently prepared samples, preferably using the same nuclear fraction. The predicted 53.4 kDa mass helps locate a candidate band but does not establish its identity.
Where should DMRTA2 appear on a Western blot?
Interpretation · DMRTA2 has a predicted mass of 53.4 kDa. No observed band position is supplied, so treat this as a reference for identifying a candidate band, not a guaranteed apparent mass.

The supplied features list no modified residues or glycosylation sites. An upper band alone cannot establish a modification or explain its apparent mass.

DMRTA2 is annotated as nuclear. A nuclear-enriched sample is consistent with that location; keep the fraction consistent when comparing samples.

Compare candidate bands with the predicted 53.4 kDa mass and the annotated nuclear location. The supplied features do not identify an observed band, alternative sequence, or modification that would assign an unexpected band to DMRTA2.
