Quantification of ricin A-chain and B-chain in replicate extractions from R. communis gibsonii and zanzibarensis seeds. Measured amount of ricin A-chain (dark gray) and B-chain (light gray) are in fmol from five individual replicate extractions from the gibsonii variety of seed and three individual extractions from the zanzibarensis seeds. Each value represents the mean of six individual IDMS replicates; error bars show one standard deviation from the mean.
