Bioactivity Comments

We have been unable to find any publicly available affinity value for the interaction between tositumomab and its antigen, CD20. The patent covering the use of radioactively-labelled anti-CD20 antibodies [2] refers back to articles and abstracts published in the early 1980's [1,3], none of which provide affinity data.
