Bovine serum albumin superparamagnetic iron oxide nanoparticles (BSA·SPIONs) conjugated with near infra-red fluorescent dyes, Cy5 or Cy7, and monoclonal anti-plectin antibody specifically were shown to associate with CSF-plectin in pancreatic cancer cells and mice tissue [174]. This evidence concerns the gene PLEC and pancreatic neoplasm.
