Description_x000D_ General description_x000D_ PMP22 (peripheral myelin protein-22) is a tetraspan integral membrane protein, that contains four putative transmembrane domains. It is expressed in the peripheral nervous system. PMP22 is produced by myelinating Schwann cells. It is an important constituent of peripheral myelin. This gene is mapped to human chromosome 17p11.2._x000D_ Immunogen_x000D_ synthetic peptide corresponding to amino acid residues 118-133 of human PMP22, with an added cysteine, conjugated to KLH. The corresponding sequence differs by 3 amino acids in rat and mouse._x000D_ Physical form_x000D_ Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide._x000D_ Disclaimer_x000D_ Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals._x000D_ Legal Information_x000D_ BiotinTag is a trademark of Sigma-Aldrich Co.
