Used in biomedical research to quantify levels of Multidrug Resistance Related Protein 1 (MRP1) in human samples. Enables assessment of MRP1 expression in cancer studies, particularly in understanding drug resistance mechanisms in tumor cells. Supports research in pharmacology and oncology by providing a reliable method to measure protein changes in response to drug treatments. Useful for evaluating the effectiveness of new therapeutic agents that aim to overcome multidrug resistance. Commonly applied in cell culture studies, clinical sample analysis, and biomarker validation.
