PLK1 (PLK or STPK13) Antibody - FFPE Validated

Biological Background

Use this antibody to assess PLK1 in your model system. PLK1 is a signaling protein that can relay information through phosphorylation and complex assembly. Focus on trends across conditions rather than single-point snapshots.

In some datasets and protocols, it is referenced by the gene symbol STPK13.

Use in the Laboratory

Parallel measurement of upstream inputs and downstream readouts can sharpen interpretation of pathway behavior. Pair measurements with orthogonal readouts when interpretation is sensitive to context.

Depending on the model, researchers may ask whether signal shifts reflect altered abundance, compartment changes, or remodeling of associated complexes.

To keep datasets interpretable, labs often document:

• localization shifts between cytoplasm, membrane, and nucleus
• interaction patterns within multi-protein complexes
• time-resolved changes following stimulation or inhibition
• condition-to-condition comparisons with matched controls

Version Notes

In sectioned tissue workflows, interpretation often depends on morphology; this format supports that style of readout. If your study compares multiple conditions, keep acquisition and processing settings stable to avoid confounding.

To support downstream analysis, record key context variables (culture timing, stimulation window, and extraction approach) so PLK1 patterns can be compared across experiments without guesswork.

When interpreting PLK1, consider whether changes track with compartment identity, cell density, or perturbation timing; these factors can influence apparent signal without implying a direct causal link.

Choose the fixed-section option when you want PLK1 results aligned to your sample format.
