Used in biomedical research to measure levels of hypoxia inducible factor alpha (HIFα) in cell or tissue samples. Helps researchers study cellular responses to low oxygen conditions, which is relevant in cancer, cardiovascular diseases, and ischemic disorders. Enables quantification of HIFα protein expression in experimental models, supporting drug development and mechanistic studies in hypoxia-related pathways. Commonly used in molecular biology and medical research labs for reliable and specific detection of HIFα in human samples.
