Used in research settings to quantify levels of Perilipin-1 protein in biological samples, particularly in studies related to lipid metabolism and adipocyte function. Enables investigation into obesity, insulin resistance, and metabolic disorders by measuring protein expression changes in response to hormonal, dietary, or pharmacological interventions. Commonly applied in preclinical studies using mouse models to assess fat cell regulation and lipolysis mechanisms. Provides a reliable, sensitive method for detecting PLIN1 in tissue lysates or cell extracts, supporting advancements in metabolic disease research.
