RBP4 Antibody

About the Target

RBP4 (Retinol-binding protein 4) is a secreted protein of the lipocalin family, primarily synthesized in the liver and adipose tissue, and serves as the principal transporter of retinol (vitamin A) in the bloodstream. Beyond its classical role in retinol transport, RBP4 functions as a multifaceted adipokine that regulates insulin sensitivity, glucose metabolism, lipid homeostasis, inflammation, mitochondrial function, and cellular apoptosis, particularly in skeletal and cardiac muscle. Depending on the literature source, RBP4 may also be discussed as Stathmin and Stathmin 1.

Reported cellular context includes secreted, which can matter when signal is compared across treatments or changing cell states. Following RBP4 across matched perturbations can help separate abundance effects from shifts in localization, complex assembly, or pathway state.

Research Context

RBP4 is commonly interpreted in the context of cardiovascular and metabolism research, and readouts are often stronger when a study separates expression changes from compartment-level redistribution. When reported signal spans secreted, 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 secreted relative to the broader cellular background
• changes linked to vascular, contractile, or hemodynamic cell-state cues
• responses linked to nutrient status, mitochondrial state, or metabolic rewiring
• co-patterning with orthogonal markers and control conditions that clarify pathway state

Variant Considerations

If your project spans exploratory questions, the regular version offers a balanced option for establishing baseline signal behavior for RBP4. 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 RBP4 reflect biology rather than handling. When interpreting RBP4, 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 RBP4 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.
