What Is the Expected KDM1A Western Blot Band Size?

KDM1A is predicted at 92.9 kDa and observed near 100 kDa; the cause of this difference is not established.

What am I looking at on my blot?
Band near 100 kDaEmpirical KDM1A band in whole-cell lysates; confirm identity with controls.
Band near 93 kDaNear the 92.9 kDa predicted mass; identity requires confirmation.
Multiple discrete bandsCould reflect isoforms 1, 2, 3, or 4; their migration is unknown.
Weak or absent band in soluble lysateChromatin-associated nuclear KDM1A may be poorly recovered.
💡Expected KDM1A appearanceKDM1A has a predicted mass of 92.9 kDa, while antibody QC shows a band near 100 kDa; the cause of the difference is unestablished, so confirm identity with appropriate controls.

Band lower than expectedAn isoform is possible, but isoform masses are not supplied.Check KDM1A depletion and compare isoform expression.
Multiple bandsIsoforms 1 through 4 are annotated, but distinct band positions are unproven.Use KDM1A depletion to identify specific bands.

Sample controls for KDM1A Western blot

🧪HPA-IHC candidate guidance (verify in WB): For positive controls for KDM1A in Western blot, you can use adrenal gland tissue, which HPA rates as highly positive.
Positive control: Adrenal gland (IHC candidate; verify WB)
Negative control: Prostate (IHC candidate; verify WB)
Loading controls: Run GAPDH, β-actin, and a total-protein stain such as Ponceau alongside the samples.
⚠️Feasibility: KDM1A is nuclear and chromatin associated, so nuclear lysate may improve detection.

Advanced KDM1A Western Blot Tips

Deeper troubleshooting and optimisation questions for KDM1A, answered from its protein features.

How should KDM1A 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 KDM1A isoforms produce different bands?
Isoforms · UniProt lists four isoforms. Isoforms 2 and 3 have a sequence insertion at canonical position 173; isoforms 2 and 4 have one at position 369. Check which isoforms your sample and antibody can detect when interpreting nearby bands. These annotations alone do not predict their apparent positions.
Which phosphorylation sites matter when interpreting KDM1A bands?
PTM · In UniProt canonical numbering, phosphorylation is annotated at Thr59, Thr104, Ser126, Ser131, Tyr135, Ser137, Ser166, Ser611, and position 849, which is listed as phosphoserine and phosphothreonine. Check the numbering convention of a site-specific antibody before comparing labels. These sites do not establish a visible band shift.

UniProt lists N6-acetyllysine at canonical positions 432, 433, and 436. Check whether an antibody recognizes a region containing these residues when comparing signals. Their presence does not establish a visible shift or explain the approximately 100 kDa band.
Does this guide establish induction of KDM1A?
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 KDM1A?
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 M00532-1 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 KDM1A 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.
Why does KDM1A appear near 100 kDa instead of 92.9 kDa?
Interpretation · The supplied blot observation is approximately 100 kDa, while the predicted mass is 92.9 kDa. Apparent migration can differ from calculated mass. The listed isoforms and modifications do not, by themselves, establish the cause of this difference.

KDM1A is annotated in the nucleus and on chromosomes, with chromatin association. A nuclear or chromatin-containing preparation is relevant when assessing a weak signal; keep the fraction consistent across samples.

Because KDM1A associates with chromatin and forms complexes with RCOR1 and with RCOR/GFI/HDAC components, compare like fractions prepared the same way. Normalize for loading within that fraction, and distinguish a change in fraction recovery from a change in KDM1A abundance.

Compare them with the approximately 100 kDa observed band and consider the four annotated isoforms and listed modifications as possibilities to investigate. No signal peptide, propeptide, or glycosylation site is listed. The supplied features alone cannot identify an unexpected band or assign its cause.

Real WB data Western blot analysis of KDM1/KDM1A using anti-KDM1/KDM1A antibody (M00532-1). <br>Electrophoresis was performed on a 10% SDS-PAGE gel at 80V (Stacking gel) / 120V (Resolving gel) for 2 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions. <br>Lane 1: human SIHA whole cell lysates,<br>
Lane 2: human SH-SY5Y whole cell lysates,<br>
Lane 3: human HepG2 whole cell lysates.<br>After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-KDM1/KDM1A antigen affinity purified monoclonal antibody (M00532-1) at 1: 1000 overnight at 4°C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an ECL Plus Western Blotting Substrate (Catalog # AR1196-200) with Tanon 5200 system. A specific band was detected for KDM1/KDM1A at approximately 100 kDa. The expected band size for KDM1/KDM1A is at 93 kDa.
Anti-KDM1/LSD1 KDM1A Rabbit Monoclonal Antibody
Cat # M00532-1

The catalog reports one anti-KDM1A antibody, M00532-1, with stated human, mouse, and rat reactivity. Its WB image uses three human cell lysates and shows a band near 100 kDa; the expected size is 93 kDa. Mouse and rat WB samples are not shown.

Which to pick: M00532-1 is the only listed option. Its WB image supports use in the tested human SIHA, SH-SY5Y, and HepG2 lysates at 1:1000; assess mouse or rat samples separately, since the supplied WB image covers human lysates only.
