EpCAM (CD326 or 17-1A antigen or TACSTD1) Antibody - FFPE Validated

Biological Background

For consistent comparison across experiments, use this antibody to evaluate EpCAM with a repeatable workflow. EpCAM is a lineage-associated marker that supports stratification of immune populations in model systems. For comparison-heavy studies, consistent sample handling and normalization help reduce run-to-run drift.

In some datasets and protocols, it is referenced by the gene symbol CD326.

Use in the Laboratory

Immune markers are often interpreted alongside a panel of complementary targets to improve population resolution. Define inclusion criteria and controls early so replicate sets remain interpretable as the dataset grows. It can be informative in studies that track epithelial differentiation, polarity shifts, or junction remodeling.

Many targets show context-dependent localization, so comparisons across matched conditions can reveal meaningful patterns.

To keep datasets interpretable, labs often document:

• panel-based interpretation with additional lineage markers
• assessment of surface versus internalized pools
• activation-dependent changes across stimulation conditions
• comparisons across differentiation or polarization states

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. A brief pilot run can help set exposure ranges and reduce reruns later.

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

For multi-run studies, the fixed-section option helps keep EpCAM trends comparable from experiment to experiment.
