Descripción

General description

PEMT (phosphatidylethanolamine N-methyltransferase) is an an important enzyme for the synthesis of membrane phospholipids. PEMT converts phosphatidylethanolamine to phosphatidyl-choline by sequential methylation in the liver. The protein localizes to the endoplasmic reticulum and mitochondria-associated membranes. The gene is within the Smith-Magenis syndrome region on chromosome 17. Inhibition of hepatic PEMT activity has been associated with Alzheimer’s disease and schizophrenia.

Specificity

Other homologies: Mouse (86% sequence homology) and Rat (73% sequence homology).

This antibody recognizes the C-terminal region of human PEMT in Jurkat cell lysates. The antibody easily detected PEMT in Jurkat and L6 lysates by Western blotting, but expression was weak or not detected in A431, HeLa, HEK293, PC12, or NIH/3T3 cell lysates using very dilute antibody (0.25 μg/mL, data not shown). Positive signals in immunocytochemistry using higher concentrations of antibody (2.5 μg/mL) detected PEMT in these cell lines, suggesting differential expression levels of this protein in various cell lines.

Immunogen

Epitope: C-terminus

The immunogen was a KLH-conjugated synthetic peptide corresponding to the C-terminal region of human PEMT.

Application

ELISA:
This antibody was reported by an outside laboratory to be suitable for ELISA

Immunocytochemistry:
HeLa, A431, and NIH/3T3 (previous page) cells incubated with anti-PEMT (C-terminus) stained positively on nuclei and endoplasmic reticulum (ER).

This PEMT antibody is validated for use in WB, ICC & ELISA for the detection of the PEMT protein.

Quality

Western Blot Analysis:
1:1,000 dilution of this antibody detected PEMT on 10 µg of L6 lysate (below) and Jurkat lysate (not shown).
