Used in biomedical research to measure levels of phosphodiesterase 3B enzyme in mouse samples, aiding studies on insulin signaling, lipid metabolism, and diabetes-related pathways. Enables quantification of PDE3b protein in tissues like adipose, liver, and pancreatic cells, supporting investigation into metabolic disorders and drug development. Commonly applied in preclinical studies to assess molecular responses to therapeutic compounds targeting metabolic and endocrine functions.
