Used in research to block or neutralize Leukemia Inhibitory Factor (LIF) activity, this antibody helps study LIF's role in cell signaling, stem cell differentiation, and inflammation. It is applied in immunoassays and flow cytometry to detect LIF or investigate its function in disease models such as cancer, autoimmune disorders, and reproductive health. Due to its specificity, it serves as a reference tool for evaluating other anti-LIF agents in preclinical studies.
