DR5 Antibody

About the Target

Death receptor 5 (DR5), also known as TRAIL-R2, TNFRSF10B, or CD262, is a type I transmembrane protein in the tumor necrosis factor (TNF) receptor superfamily, primarily recognized for its role in apoptosis. It comprises an extracellular cysteine-rich domain, a transmembrane segment, and an intracellular death domain essential for downstream signaling. Depending on the literature source, DR5 may also be discussed as CD262 and KILLER.

Reported cellular context includes membrane, which can matter when signal is compared across treatments or changing cell states. Following DR5 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

DR5 is commonly interpreted in the context of cancer, inflammation, and infectious disease 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
• responses associated with cytokine exposure, inflammatory tone, or tissue stress
• host-response changes during infection or pathogen-associated stimulation

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for DR5. 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 DR5 reflect biology rather than handling. When interpreting DR5, 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 DR5 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.
