Phospho-Vimentin (Ser39) Antibody

About the Target

Phospho-vimentin (Ser39) refers to the vimentin intermediate filament protein phosphorylated at serine 39, a modification that plays a critical role in regulating filament dynamics and cellular architecture. Vimentin is a type III intermediate filament protein predominantly expressed in mesenchymal cells, serving as a major component of the cytoskeleton that provides mechanical stability, maintains cellular integrity, and supports intracellular transport. Depending on the literature source, VIMENTIN may also be discussed as Phospho-Vimentin (Ser39).

Reported cellular context includes cell membrane, cytoplasm, cytoskeleton, and intermediate filament, which can matter when signal is compared across treatments or changing cell states. Following VIMENTIN across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

VIMENTIN is commonly interpreted in the context of cancer research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane, cytoplasm, and cytoskeleton, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between cell membrane, cytoplasm, and cytoskeleton across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• differences between total target abundance and site-specific regulation when modified forms are compared
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for VIMENTIN. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in VIMENTIN reflect biology rather than handling. When interpreting VIMENTIN, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep VIMENTIN trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
