Description
Catalytic hydrogenation of ochratoxin A by carrier-free tritium was used to prepare 3H-ochratoxin B with a high specific activity. Iodination of ochratoxin B by carrier-free Na 125I using the chloramine method yielded 125I-ochratoxin with a high specific activity. Another 125I-derivative of ochratoxin A was prepared by iodination of an ochratoxin A - L-tyrosine-methylester conjugate. All three radioactive preparations were found to be useful for radioimmunoassay. (author)
