JAM-B (JAM2 or CD322) Antibody - FFPE Validated

Biological Background

This antibody enables you to investigate JAM-B with a direct, biology-first readout. JAM-B is a structural regulator of intercellular boundaries and tissue architecture. Look for shifts in distribution that track with phenotype changes.

In some datasets and protocols, it is referenced by the gene symbol JAM2.

Use in the Laboratory

Researchers often monitor junctional targets when studying epithelial integrity, remodeling, and motility. Pair measurements with orthogonal readouts when interpretation is sensitive to context.

Depending on the model, researchers may ask whether signal shifts reflect altered abundance, compartment changes, or remodeling of associated complexes.

To keep datasets interpretable, labs often document:

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

Version Notes

This fixed-section oriented version is intended for paraffin-embedded tissue, where crosslinking and retrieval steps can shape epitope accessibility. If your study compares multiple conditions, keep acquisition and processing settings stable to avoid confounding.

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

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

Select the fixed-section version to keep JAM-B interpretation aligned with your workflow goals.
