Integrin β 3 Antibody

About the Target

ITGB3 is a target of interest in many antibody-based workflows. Integrin β3 is a key subunit of the integrin family of transmembrane receptors that mediate cell adhesion to the extracellular matrix (ECM) and transduce signals bidirectionally across the plasma membrane. It commonly pairs with αV or αIIb subunits to form the αVβ3 and αIIbβ3 integrins, which play essential roles in diverse biological processes such as platelet aggregation (αIIbβ3), angiogenesis, cell migration, and survival (αVβ3). Depending on the literature source, ITGB3 may also be discussed as Integrin beta 3 and CD61.

Reported cellular context includes cell junction, cell membrane, cell projection, and membrane, which can matter when signal is compared across treatments or changing cell states. Following ITGB3 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

ITGB3 is commonly interpreted in the context of cancer, immunology, and cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell junction, cell membrane, and cell projection, 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 junction, cell membrane, and cell projection across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• context differences tied to immune-cell state, activation, or lineage composition
• signal-dependent shifts after ligand, inhibitor, or growth-factor perturbation

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for ITGB3. 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 ITGB3 reflect biology rather than handling. When interpreting ITGB3, 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 ITGB3 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.
