Used in biomedical research to measure levels of Proline Hydroxylase Domain enzyme 1 (PHD1) in human samples. Helps study hypoxia-related pathways, as PHD1 regulates the stability of hypoxia-inducible factors (HIFs). Commonly applied in research on cancer, cardiovascular diseases, and metabolic disorders where oxygen sensing plays a critical role. Enables quantitative analysis of PHD1 protein expression in cell lysates, tissue homogenates, and serum, supporting drug development and mechanistic studies in cellular response to low oxygen conditions.
