BD Transduction Laboratories™ Purified Mouse Anti-Carboxypeptidase E
Clone 35/Carboxypeptidase E (RUO)
Western blot analysis of Carboxypeptidase E on rat brain lysate (left panel). Lane 1: 1:2500, lane 2: 1:5000, lane 3: 1:10000 dilution of Carboxypeptidase E,
Immunofluorescent staining of SH-SY5Y cells (right panel). Cells were seeded in a collagen coated 384 well imaging plate (Material # 353962) at ~ 8,000 cells per well. After overnight incubation, cells were stained using the Triton X100 fix/perm protocol (see Recommended Assay Procedure) and the anti-Carboxypeptidase E antibody. The second step reagent was Alexa Fluor® 488 goat anti mouse Ig (Invitrogen). The image was taken on a Pathway 855 or 435 imager using a 20x objective. This antibody also stained SK-N-SH and C6 cells using both the Triton X100 and methanol fix/perm protocols (see Recommended Assay Procedure).

Recommended Assay Procedures
Methanol Procedure for a 96 well plate:
Remove media from wells. Add 100 µl/well fresh 3.7% Formaldehyde in PBS. Incubate for 10 minutes at room temperature (RT). Flick out and add 100 µl/well 90% methanol. Incubate for 5 minutes at RT. Flick out and wash twice with PBS. Flick out PBS and add 100 µl/well blocking buffer (3% FBS in PBS). Incubate for 30 minutes at RT. Flick out and add diluted antibody (diluted in blocking buffer). Incubate for 1 hour at RT. Wash three times with PBS. Flick out PBS and add second step reagent. Incubate for 1 hour at RT. Wash three times with PBS. Image sample.

Antibody Details
35/Carboxypeptidase E
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 α-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.

Format Details
Purified
Tissue culture supernatant is purified by either protein A/G or affinity purification methods. Both methods yield antibody in solution that is free of most other soluble proteins, lipids, etc. This format provides pure antibody that is suitable for a number of downstream applications including: secondary labeling for flow cytometry or microscopy, ELISA, Western blot, etc.
