Alternative NamesSaponaria officinalis; Common soapwort
Scientific BackgroundSaporin is a ribosome-inactivating protein (RIP) of type I. This monomeric RNA N-glycosidase purified from seeds of the plant Saponaria officinalis also known as Soapwort, is capable of specific depurination of eukaryotic ribosomes thus arresting protein synthesis. No ligand has been identified in saporin hence its inability to transverse the cell membrane. Due to its toxicity and stability of the structure, saporin has proven extremely useful for construction of immunotoxins. The expected molecular weight of the purified saporin is 29.5 kDa.
Western blot analysis using rabbit polyclonal anti-saporin antisera (R-025-100). HRP-labelled sheep anti-rabbit was used as the secondary antibody and the immunocomplex was then visualised by DAB. The expected molecular weight of the purified saporin is 29.5 kDa. SC: Spinal Cord homogenate (rat).
