MR. A. L. BACHARACH‘s letter 1 on the use of the plate-and-cylinder method in reverse for assaying certain growth-factors suggests that it may be of interest to record some very similar ...

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 ...

[32] To show the ability of the microbiological assay to unambiguously assess the API in presence of all other expected components in a pharmaceutical-grade product for clinical use (specificity ...

Credible reference materials can help identify and normalize sources of assay bias and improve the consistency and reproducibility of data. The human body harbors diverse, dynamic microbial ...

“Complex” media are used in the growth of a majority of heterotrophic organisms; “defined” media are used for microbiological assays, photoautotrophs, chemoautotrophs, and for growing ...
