WebOct 8, 2016 · The simulated assays were based on the standard approach for a parallel line in vivo assay (such as immunopotency), which includes parallelism assessment. The simulated bioassays compared a reference preparation with a test preparation using four doses of each preparation. The doses were equally spaced on the log scale. WebThe use of the parallel line assay method and the expression of the potency relative to that of the reference vaccine gave a reliable estimate of the potency of HB vaccine.
