Ricin toxin is a glycoprotein isolated from the seeds of Ricinus communis (R. communis), the castor bean plant. The sequence for the R. communis gene for the ricin toxin precursor protein has been reported (GenBank: X03179). Ricin toxin has a molecular weight of approximately 63,000 daltons. Using Western blot analysis, NR-2485 reacted with anti-ricin polyclonal antiserum, but did not react with unrelated polyclonal antiserum. NR-2485 is active in an in vitro cytotoxicity assay using Vero cells.

Each vial of NR-2485 contains approximately 5 mg of ricin toxin suspended in phosphate buffered saline (pH 7.8).
