What Is the Expected KIF11 Western Blot Band Size?

KIF11 is predicted at 119.2 kDa; listed modifications could affect migration, but no empirical band or demonstrated shift is supplied.

What am I looking at on my blot?
Single band near 119.2 kDaconsistent with predicted full-length KIF11 size; confirm identity with a specificity control
Band in a cytoplasmic fractionconsistent with KIF11 cytoplasmic localization
Band in a spindle-pole fractionconsistent with KIF11 spindle-pole localization
Nearby doublet around 119.2 kDacould reflect listed phosphorylation states, but distinct migration is unproven
💡Expected KIF11 appearanceFull-length KIF11 has a predicted mass of 119.2 kDa; no empirical band size or modification-dependent shift is supplied, so confirm any candidate band with a specificity control.
How each factor affects band size
UniProt predicted massplaces full-length KIF11 near 119.2 kDa
Phosphothreonine at T458may affect migration, but no size shift is established
Phosphothreonine at T925 and T926may affect migration, but no size shift is established
Phosphoserine at S1033may affect migration, but no size shift is established
N6-acetyllysine at K146has no established visible size effect

Sample controls for KIF11 Western blot

🧪HPA-IHC candidate guidance (verify in WB): For positive controls for KIF11 in Western blot, you can use appendix tissue, which HPA rates as high expression.
Positive control: Appendix (IHC candidate; verify WB)
Negative control: Caudate (IHC candidate; verify WB)
Loading controls: Run GAPDH, β-actin, and a total-protein stain alongside the samples.
⚠️Feasibility: Tissue controls are feasible because KIF11 is intracellular, with high expression in appendix and no detected expression in caudate.

Advanced KIF11 Western Blot Tips

Deeper troubleshooting and optimisation questions for KIF11, answered from its protein features.

How should KIF11 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 a second band represent a KIF11 isoform?
Isoforms · The supplied features list one isoform and no alternative sequence. They do not support assigning a second band to a KIF11 isoform.
Which KIF11 phosphorylation sites matter when interpreting bands?
PTM · UniProt lists phosphothreonine at positions 458, 925 and 926, with CDK1 specified for 926, and phosphoserine at 1033 by NEK6. These are UniProt coordinates; paper or antibody numbering may differ. Their presence does not establish a visible band shift.

UniProt lists N6-acetyllysine at position 146. Use UniProt numbering when comparing this site with antibody or paper annotations. The feature alone does not predict a distinct Western blot band.
Does this guide establish induction of KIF11?
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 KIF11?
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 M01754-3 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.
What should be controlled when quantifying KIF11 bands?
Quantitation · Compare similarly prepared samples and account for KIF11's cytoplasmic and spindle pole localization, especially if using fractions. Normalize loading and keep cell cycle conditions comparable when interpreting differences.
Should KIF11 run at exactly 119.2 kDa?
Interpretation · 119.2 kDa is the predicted mass; no observed band position is supplied. The listed modifications do not, by themselves, establish a visible shift or explain any difference between apparent and predicted mass.

KIF11 is annotated for cell cycle, cell division and mitosis, with localization to the cytoplasm and spindle pole. Record cell cycle conditions when comparing samples; the supplied features do not establish that a particular treatment increases KIF11 abundance.

Compare them with the 119.2 kDa predicted mass, but avoid assigning identities from position alone. The supplied features list one isoform, acetyllysine 146 and four phosphorylation sites; none proves that an extra band is a specific KIF11 form. No empirical band position is supplied.

Anti-Eg5 Rabbit Monoclonal Antibody
Cat # M01754-3
Real WB data Western blot analysis of Eg5/KIF11 using anti-Eg5/KIF11 antibody (A01754-2). Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions. Lane 1: human MCF-7 whole cell lysates, Lane 2: human Raji whole cell lysates, Lane 3: human 293T whole cell lysates, Lane 4: human Daudi whole cell lysates, Lane 5: human MOLT-4 whole cell lysates. 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-Eg5/KIF11 antigen affinity purified polyclonal antibody (Catalog # A01754-2) at 0.5 μg/mL 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 Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for Eg5/KIF11 at approximately 130 kDa. The expected band size for Eg5/KIF11 is at 119 kDa.
