DR4 Antibody

About the Target

The tumor necrosis factor receptor family, comprising TNF-RI, Fas, DR3, DR4, DR5, and DR6, holds significant sway over apoptosis regulation across various physiological systems. DR4 (also known as TRAIL-RI or TNFRSF10A) and DR5 (also known as TRAIL-R2 or TNFRSF10B) serve as receptors for the cytokine TRAIL. Depending on the literature source, DR4 may also be discussed as CD261 and TRAIL-R1.

Reported cellular context includes cell membrane, cytoplasm, and membrane, which can matter when signal is compared across treatments or changing cell states. Following DR4 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

DR4 is commonly interpreted in the context of apoptosis research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane, cytoplasm, and membrane, a defined reference condition can make comparisons more interpretable across perturbations, passages, or replicate sets.

Consider these angles when interpreting target-level changes:

• apparent redistribution between cell membrane, cytoplasm, and membrane across matched conditions
• separation of survival-associated changes from stress or death-associated readouts
• co-patterning with orthogonal markers and control conditions that clarify pathway state
• time-matched comparisons so changes reflect biology rather than handling or sampling drift

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for DR4. 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 DR4 reflect biology rather than handling. When interpreting DR4, 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 DR4 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.
