Cup plate assay
WebA microbiological potency assay measures the effectiveness of an antibiotic by the degree of growth inhibition on susceptible strains of microorganisms at differing concentrations. One of the two methods defined in the pharmacopoeia to make this determination is the Diffusion (Cylinder-Plate) method. WebThe Cylinder-Plate Assay is based upon the ability of the antibiotic being assayed and its corresponding Reference Standard to diffuse through the agar and form a ‘zone of clearing’ (‘zone of inhibition’) thereby killing the microorganism which …
