LGR5 Antibody

About the Target

Leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5), also known as GPR49, is a seven-transmembrane protein belonging to the class A Rhodopsin-like family of GPCRs. It is characterized by a large extracellular domain with 17 leucine-rich repeat (LRR) sequences, a linker region, and a seven-transmembrane helical domain.

Reported cellular context includes cell membrane, golgi apparatus, and membrane, which can matter when signal is compared across treatments or changing cell states. Following LGR5 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

LGR5 is commonly interpreted in the context of developmental biology, stem cell biology, and cell signaling research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans cell membrane, golgi apparatus, 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, golgi apparatus, and membrane across matched conditions
• stage-dependent patterns during differentiation, morphogenesis, or lineage commitment
• state transitions between self-renewal, priming, and differentiation
• 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 LGR5. 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 LGR5 reflect biology rather than handling. When interpreting LGR5, 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 LGR5 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.
