GRADE & PURITYAnimal Free?Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material.Carrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥95%(SDS-PAGE)

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.
