We now offer new biostatistical evaluation features using our new software “PLA Software 3.0 from Stegmann Systems”. During the quality control process, the biological activity of drugs must be analysed and this can be carried out using a potency assay an example of which being the Parallel-Line Assay. In this assay, a dose response curve is created through many serial dilutions. By comparison with a standard the biological activity of a drug can be determined. For such an evaluation we are now able to use the “PLA Software 3.0 from Stegmann Systems”.
