There is also a general purpose assay type that can be customized by an administrator to capture any sort of experimental data. ), optional validation or parsing/formatting information. The antigen is then detected by an antibody directly conjugated to an enzyme such as HRP. There are mainly two different types of microbiological assays usually encountered bearing in mind the response of an ever-growing population of microbes vis-a-vis ascertaining the profile of antimicrobial agent measurements, such as : (a) Agar Plate diffusion assays, and (b) Rapid-reliable-reproducible microbial assay methods. There are several types of assays that can be performed and used to determine the value of all kinds of metal objects â from jewelry to bullion bars. In this context, a molecular assay is used to determine whether a patient is actively infected with the pathogen of interest. Built-in assay types include Luminex, Elispot, Microarray, etc. Patient Ag and reagent labeled Ag are introduced to assay at same time.
