PIK3R3 (p55 or p55-GAMMA) Antibody - FFPE Validated

Scientific Overview

This antibody enables you to analyze PIK3R3 with a direct, biology-first readout. PIK3R3 is a signaling node often evaluated by abundance, localization, and modification-dependent states. Focus on trends across conditions rather than single-point snapshots.

In some datasets and protocols, it is referenced by the gene symbol p55.

Research Relevance

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.

When cell-state transitions occur, this target may change alongside partners in the same compartment or pathway neighborhood.

When building a narrative around the target, it helps to track:

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

Application-Specific Context

This fixed-section oriented version is intended for paraffin-embedded tissue, where crosslinking and retrieval steps can shape epitope accessibility. Think about how preparation affects epitope accessibility, and interpret patterns alongside morphology and compartment markers as needed.

If your study spans multiple model systems, it can help to define a shared reference condition for PIK3R3 so cross-sample contrasts stay meaningful.

For challenging targets, pairing PIK3R3 measurements with a second marker can clarify whether differences arise from regulation, redistribution, or shifts in cell composition within the sample.

With a clear focus on PIK3R3, this fixed-section option fits streamlined studies and fast iteration.
