An International Proficiency Test to Detect, Identify and Quantify Ricin in Complex Matrices
Toxins, 2015 While natural intoxications with seeds of Ricinus communis (R. communis) have long been known, the toxic protein ricin contained in the seeds is of major concern since it attracts attention of those intending criminal, terroristic and military misuse. In

Biological Activity of Heated Diphtheria Toxin [PDF]
Journal of Bacteriology, 1973 Diphtheria toxin splits into two fragments when heated at 100 C for 10 min in a phosphate buffer. The separated fragments have molecular weights of 24,000 and 39,000, respectively. These molecular weights are similar to those of the A and B fragments found in diphtheria toxin preparations after thiol reduction.
