    Abstract

    Alpha-Enolase (ENO1), Identified as an Antigen to Monoclonal Antibody 12C7, Promotes the Self-Renewal and Malignant Phenotype of Lung Cancer Stem Cells by AMPK/mTOR Pathway

    Immunofluorescence was used for antigen localization. After targeted antigen purification by electrophoresis and immunoblot, the antigen was identified by LC-MALDI-TOF/TOF mass spectrometry, immunofluorescence, and immunoprecipitation.
