Microbial Assays for Antibiotics Package
The Microbial Assays for Antibiotics Package for PLA 3.0 is your software for assessing the potency of antibiotics. This add-on supports various methods, that is, cylinder-plate, turbidimetric, and combination of microbial assays. It enables you to closely follow the guidelines laid out in the United States Pharmacopeia (USP <81>) and the Japanese Pharmacopoeia (JP 4.02).
Cylinder plate assays (USP <81>)
Use Cylinder plate assay (USP <81>) documents to determine the potency of antibiotics according to the cylinder-plate method described in USP <81>. PLA 3.0 uses a linear regression model to fit the standard curve. This method allows you to correct for plate-to-plate variation.
