Recombinant Human Carboxypeptidase E/CPE Protein (rp144654) - SDS-PAGE 3 μg/lane of Recombinant Human Carboxypeptidase E/CPE Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the band at 52 kDa. CPE is a protease (carboxypeptidase). Even if certain regulatory domains were removed or mutations were introduced during recombinant expression to reduce its activity, its catalytic domain may still retain a certain level of residual enzymatic activity. During purification, storage, or sample handling, CPE molecules might undergo slow self-cleavage (autoproteolysis) against themselves or each other, producing stable fragments of specific sizes.
