PP2A B Subunit Antibody

About the Target

PPP2R2A is a target of interest in many antibody-based workflows. Protein phosphatase type 2A (PP2A) is an indispensable serine/threonine phosphatase found across all eukaryotes. It holds a pivotal role in numerous signal transduction pathways, governing essential cellular functions such as DNA replication, transcription, translation, metabolism, cell cycle regulation, cell division, apoptosis, and development. The core enzyme comprises catalytic C and regulatory A (or PR65) subunits, each available in α and β isoforms. Depending on the literature source, PPP2R2A may also be discussed as PP2A B Subunit and PP2A-B55-alpha.

Reported cellular context includes cytosol and nucleoplasm, which can matter when signal is compared across treatments or changing cell states. Following PPP2R2A across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

PPP2R2A is commonly interpreted in the context of metabolism research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cytosol and nucleoplasm, 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 cytosol and nucleoplasm across matched conditions
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring
• co-patterning with orthogonal markers and control conditions that clarify pathway state
• time-matched comparisons so changes reflect biology rather than handling or sampling drift

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for PPP2R2A. 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 PPP2R2A reflect biology rather than handling. When interpreting PPP2R2A, 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 PPP2R2A 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.
