PLVAP (PV1) Antibody - FFPE Validated

Biological Background

When control selection matters, this antibody helps you assess PLVAP in a structured study. PLVAP is a contact-site protein that shapes barrier properties and signaling at the cell surface. Plan positive and negative controls that match your model system, including perturbations expected to shift the target.

Following PLVAP across perturbations can help separate expression effects from compartment shifts.

Use in the Laboratory

Shifts in junction organization can accompany migration, tissue morphogenesis, and altered mechanical tension. Time course design can be decisive when regulation is transient or compartment dependent. Blood-brain barrier models often monitor junction regulation alongside permeability-focused measurements.

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
• comparative profiling across cell states or perturbations
• subcellular redistribution at contact sites versus cytoplasm

Version Notes

For paraffin-embedded samples, fixation history and retrieval strategy matter; this option is aligned to those constraints. If your study compares multiple conditions, keep acquisition and processing settings stable to avoid confounding. Predefine decision rules for excluding outliers so analysis remains transparent.

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

Integrate the fixed-section version into your design so PLVAP signals can be interpreted alongside matched controls.
