    Characteristics
    1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
    2. Please refer to us for technical protocols.
    3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
    4. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
    Purification
    The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography.

    Background
    Carboxypeptidase E (CPE), also known as carboxypeptidase H and enkephalin convertase, is found as both a membrane-bound and a soluble glycoprotein in neuroendocrine tissues and adrenal-gland chromaffin granules. The C-terminus forms an amphiphilic alpha-helix, suggesting that this region is responsible for the membrane-bound form. Evidence suggests the active form of CPE is located in the secretory vesicles. CPE appears to have several functions. It is an exopeptidase that cleaves neuropeptides with C-terminal basic amino acids, producing an active form of the peptide. It has also been proposed that membrane-bound CPE is a sorting receptor for regulated secretory pathway (RSP) proteins in the TGN pituitary Golgi and secretory granule membranes. RSP proteins primarily consist of hormones and neuropeptides. Mice that carry a mutation in the CPE gene Cpe[fat] display endocrine disorders such as obesity, infertility, and hyperproinsulinemia. Furthermore, the same endocrine disorders are observed in Cpe[fat] mice where the CPE gene has been effaced by antisense RNA.
