Phospho-IGF-1R β (Tyr1135) Antibody

About the Target

IGF-1R is a target of interest in many antibody-based workflows. Phospho-IGF-I Receptor β (Tyr1135) refers to the phosphorylated form of tyrosine residue 1135 on the β-subunit of the insulin-like growth factor I receptor (IGF-IR), a transmembrane heterotetrameric tyrosine kinase receptor composed of two extracellular α-subunits and two intracellular β-subunits. Tyr1135 resides within the kinase domain of the β-subunit and plays a critical role in the receptor’s activation upon IGF-I binding. Depending on the literature source, IGF-1R may also be discussed as Phospho-IGF-1R beta (Tyr1135).

Reported cellular context includes cell membrane and membrane, which can matter when signal is compared across treatments or changing cell states. Following IGF-1R across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

IGF-1R is commonly interpreted in the context of cancer, developmental biology, and endocrinology research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane 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 and membrane across matched conditions
• changes associated with proliferative state, oncogenic signaling, or treatment response
• stage-dependent patterns during differentiation, morphogenesis, or lineage commitment
• responses to hormone-dependent signaling or endocrine feedback context

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for IGF-1R. 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 IGF-1R reflect biology rather than handling. When interpreting IGF-1R, 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 IGF-1R 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.
