A 18,956 Da major urinary protein identified by gel electrophoresis. Urine pooled from five C57BL/6J males and five females was resolved by non-denaturing (native) electrophoresis. The specific band indicated by the arrow, <i>Mup25</i>, is exclusively in male urine, and the total abundance of Mup protein is much higher in males than females. The image is modified from Figure 6A from the source.
