Anti-ACER1 antibodies are used in the immunodetection of the protein alkaline ceramidase 1. In humans, the canonical protein has a reported length of 264 amino acid residues and a mass of 31.1 kDa. Its subcellular localization is in the ER. It is reported to be mainly expressed in epidermis. A member of the Alkaline ceramidase protein family, ACER1 is known to be involved with cell differentiation and epidermis development. Synonyms for this target antigen include N-acylsphingosine amidohydrolase (alkaline ceramidase) 3, N-acylsphingosine amidohydrolase 3, acylsphingosine deacylase 3, alkCDase 1, alkaline CDase 1, and CTB-180A7.3. ACER1 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some ACER1 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
