Technical Data
C2097-72E
CTSE, ID (Cathepsin E, Cathepsin E form I, Cathepsin E form II)
Description:
CTSE is a gastric aspartyl protease that functions as a disulfide-linked homodimer. This protease, which is a member of the peptidase C1 family, has a specificity similar to that of pepsin A and cathepsin D. It is an intracellular proteinase that does not appear to be involved in the digestion of dietary protein and is found in highest concentration in the surface of epithelial mucus-producing cells of the stomach. It is the first aspartic proteinase expressed in the fetal stomach and is found in more than half of gastric cancers. It appears, therefore, to be an oncofetal antigen.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:1,000
Western Blot: 1:50-1:100
Optimal dilutions to be determined by the researcher.
