CD146 Antibody

About the Target

CD146, also known as MUC18, MCAM, Mel-CAM, S-Endo-1, and P1H12 antigen1, is a transmembrane glycoprotein belonging to the immunoglobulin superfamily that functions as a Ca2+ independent adhesion molecule. CD146 is recognized for its expression on endothelial cells, lymphocytes, and a wide range of tumor cells, where it acts as an important biomarker in cancer diagnosis and therapy. Depending on the literature source, CD146 may also be discussed as MCAM.

Reported cellular context includes membrane, which can matter when signal is compared across treatments or changing cell states. Following CD146 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

CD146 is commonly interpreted in the context of cancer and immunology research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans membrane, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• signal enrichment within membrane relative to the broader cellular background
• changes associated with proliferative state, oncogenic signaling, or treatment response
• context differences tied to immune-cell state, activation, or lineage composition
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for CD146. This can help when protocols evolve over time and the goal is to compare experiments using a stable reference workflow.

Standardize sampling time, control choice, and downstream analysis thresholds so apparent differences in CD146 reflect biology rather than handling. When interpreting CD146, it is often useful to decide early whether the main question is overall abundance, compartmental enrichment, or context-dependent redistribution.

For multi-run studies, a shared reference condition can keep CD146 trends easier to compare across datasets. That kind of consistency is especially helpful when follow-up work expands to new perturbations, model systems, or longitudinal collections.
