Other chapters explore the various aspects of agar diffusion assays, tube assays, and diffusion assays. Title:Development and Validation of Microbiological Assay for Ceftriaxone and its Application in Photo-stability Study VOLUME: 9 ISSUE: 1 Author(s):Felipe Rebello Lourenco, Marcus Augusto Lyrio Traple, Rogerio Takao Okamoto and Terezinha de Jesus Andreoli Pinto Affiliation:Departamento de Farmacia, Faculdade de Ciencias Farmaceuticas, Universidade de Sao Paulo – Av. 2009 Sep;25(9):2179-89. doi: 10.1185/03007990903116867. can purchase separate chapters directly from the table of contents HHS Latex agglutination. We compared the parameters of 22 generic products (amikacin 4, gentamicin 15, and vancomycin 3 products) against the innovator and the reference powder by Overall Test for Coincidence of the Regression Lines (Graphpad Prism 5.0). As to date, the 2D- or 3D-assay methods represent the commonest and widely accepted form of the microbiological assay. Selection of appropriate analytical tools to determine the potency and bioactivity of antibiotics and antibiotic resistance. San Diego : Academic Press, ©1989 The validation method yielded excellent results for linearity (r(2) > or = 0.98), precision (intra-assay variation < or = 11%; inter-assay variation < or = 10%), accuracy, and specificity tests according to international pharmacopoeial requirements. NLM Microbiological assay is a technique in which the potency or concentration of a compound is assessed by determining its effect on micro-organisms. This test is performed by binding antibodies or antigens to the surface of an artificial carrier called latex beads, such as polystyrene. Description. Cosgrove RF, Beezer AE, Miles RJ.

This book also explains when to use a certain microbiological assay for specific analysis, citing examples to further clarify the matter. Demonstration of equivalent amounts of the same active pharmaceutical ingredient (API) between generic and... Background. Used for the quantification of virus dilutions in a haemagglutination assay. It is a common laboratory technique which is usually used to measure the concentration of antibodies or antigens in blood. Theory and Application of Microbiological Assay first presents an overview of microbiological assay, including general principles, basic techniques, capabilities, and limitations. Improvements in the reproducibility of nystatin agar diffusion assays have been achieved by the use of liquid nitrogen stored inocula and deep frozen standard stock solutions.

Quality Control of Pharmaceuticals, Cheltenham, England, Pharmaceutical Microbiology, Glaxo Group Research, Greenford, England. Here, we report a microbiological assay using large plates designed to determine potency and concentration of pharmaceutical-grade antibiotics for injection and a statistical method to assess the in vitro equivalence of generic products with respect to the innovator. Assays are based on measurable parameters that allow differentiation between sample and control. 1–126.
