If we take into account the average value of the percentage of active abzymes in one peak, which is approximately 30–35%, and the minimum peak value of 10, as well as the number of individual colonies analyzed, then the possible number of Abzs of only κ-type with MBP-hydrolyzing activity in SLE patients can be ≥1000. This evidence concerns the gene MBP and systemic lupus erythematosus.
