Abstract: The present invention discloses methods, for differentiating between normal or reactive cells and malignant cells biological samples comprising: exposing the biological sample to an antibody to L523S protein and detecting the presence of the antibody bound to L523S protein within the malignant cells. In embodiments, such methods may further comprise: exposing the biological sample to an antibody to a second protein that is a marker of cell lineage and detecting the presence of the antibody to the second protein within cells corresponding to a particular cell lineage and/or may comprise: exposing the biological sample to an antibody to a third protein which is a marker of cells that are normal or reactive and detecting the presence of the antibody to the third protein within cells that are normal or reactive.
