Connexin-40 (Cx40 or Gja5) Antibody - FFPE Validated

Scientific Overview

Use this antibody to examine Connexin-40 in your model system. Connexin-40 is a membrane-associated component that helps organize cell-cell contacts and polarity. Look for shifts in distribution that track with phenotype changes.

Monitoring Connexin-40 alongside context markers can improve interpretation when phenotypes are subtle.

Research Relevance

Junction proteins are frequently analyzed during differentiation, stress responses, and changes in cell polarity. Pair measurements with orthogonal readouts when interpretation is sensitive to context.

Because cellular networks are interconnected, changes in this target may coincide with shifts in related pathways, trafficking behavior, or structural remodeling.

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

• subcellular redistribution at contact sites versus cytoplasm
• comparative profiling across cell states or perturbations
• changes in complex assembly with scaffold or adaptor proteins
• co-localization patterns with cytoskeletal elements

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.

To support downstream analysis, record key context variables (culture timing, stimulation window, and extraction approach) so Connexin-40 patterns can be compared across experiments without guesswork.

When interpreting Connexin-40, consider whether changes track with compartment identity, cell density, or perturbation timing; these factors can influence apparent signal without implying a direct causal link.

Select the fixed-section version to keep Connexin-40 interpretation aligned with your workflow goals.
