18 Jan 2008 Bioassay is defined as the estimation of the potency of an active principle in a unit quantity of preparation or detection and measurement of the concentration of the substance in a preparation using biological methods (i.e. observation of pharmacological effects on living tissues, microorganisms or immune
BIOASSAY; THE QUANTAL RESPONSE ASSAY. H. C. Batson. University of Illinois College of Medicine. Chicago. I. INTRODUCTION. In many instances of interest in medical and biological research, the properties, activity or potency of cer- tain substances cannot be measured directly by common in vitro chemical or
19 Apr 2015 ABSTRACT. Bioassay is defined as estimation or determination of concentration or potency of physical, chemical or biological agents by means of measuring and comparing the magnitude of the response of the test with that of standard over a suitable biological system under standard set of conditions.
