Used in biomedical research to quantify levels of ALDH1A1 enzyme in tissue samples and cell lysates. Helps in studying stem cell populations, particularly cancer stem cells, as ALDH1A1 is a known marker for identifying and isolating these cells. Applied in oncology research to investigate tumor progression, drug resistance, and patient prognosis in cancers such as breast, lung, and ovarian. Also utilized in toxicology and metabolic studies to assess alcohol metabolism and oxidative stress responses. Supports development of targeted therapies and biomarker validation in clinical and preclinical settings.
