Protocadherin-19 (PCDH19 or DEE9 or EFMR) Antibody - FFPE Validated

Scientific Overview

When you need to assess Protocadherin-19 (DEE9) with attention to cellular organization, this antibody provides a focused option. Protocadherin-19 is a membrane-associated component that helps organize cell-cell contacts and polarity. Its behavior can reflect changes in differentiation state, stress, or remodeling of cellular architecture.

In some datasets and protocols, it is referenced by the gene symbol DEE9.

Research Relevance

Researchers often monitor junctional targets when studying epithelial integrity, remodeling, and motility. Because regulation can be multi-layered, combining abundance and localization information can sharpen conclusions.

When cell-state transitions occur, this target may change alongside partners in the same compartment or pathway neighborhood. Planar polarity studies may connect this target to directional signaling and cytoskeletal alignment.

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

• changes in complex assembly with scaffold or adaptor proteins
• subcellular redistribution at contact sites versus cytoplasm
• comparative profiling across cell states or perturbations

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.

For challenging targets, pairing Protocadherin-19 measurements with a second marker can clarify whether differences arise from regulation, redistribution, or shifts in cell composition within the sample.

The fixed-section version supports deeper biological narratives around Protocadherin-19 (DEE9) without overcomplicating setup.
