Provided below are ELISA kits targeting plectin, a human protein encoded by PLEC. This protein is 4684 amino acids long, with a mass of 531.8 kDa, and is a member of the Plakin or cytolinker family. 9 isoforms have been identified. This is reported to be a cytoplasmic protein. There is a noted implication in Epidermolysis bullosa simplex with pyloric atresia. Other alias names for this protein include: hemidesmosomal protein 1, plectin 1 intermediate filament binding protein 500kDa, EBS1, EBSMD, EBSO, EBSOG, and EBSPA. ELISA kits are available that are reactive to human, mouse, rat, and plant variants of the target antigen.
