Immunogenicity testing plays a crucial role in measuring the immune response elicited by large molecule drugs during biotherapeutics R&D. Moreover, given its defense mechanism, the human immune system marks large molecules as foreign invaders and mounts a subsequent reaction. Typically, this happens through the production of antibodies to remove or destroy the external elements. During the immune response, the large molecules can create even larger macromolecules that further change the immunogenicity profile of the underlying ada assay.

Bioequivalence definition: Bioequivalence is the measurement of similar biological response between two products where one drug is replaced by another but with essentially the same structure. If a drug meets this requirement, it is considered equivalent to its brand-name counterpart and can be used as a generic version of that medication.
High Performance Liquid Chromatography (HPLC) method development, validation, and analysis is one of the most widely used techniques for drug testing in formulations and biological fluids. Usually, the first step in HPLC method development is to review existing information given substantial research has already been published on this topic. Next, an appropriate HPLC column that can provide a sharp peak with a reasonable retention time must be selected. It is imperative to select a proper HPLC column that can provide a sharp peak with a reasonable retention time. In this step, a neat solution of the analyte is chromatographed using an appropriate column. There are countless choices of HPLC columns from different vendors, and the selection of an adequate column can itself be challenging. Afterward, we should select a suitable mobile phase for sound separation of analyte from impurities or endogenous material.
In drug testing, high performance liquid chromatography (HPLC) is a method that is widely used due to its reliable results and high resolution. The first step in HPLC method development is to review existing information given substantial research has already been published on this topic. Next, it is imperative to select a proper HPLC column that can provide a sharp peak with a reasonable retention time. Afterward, we should select a suitable mobile phase for sound separation of analyte from impurities or endogenous material. Closer to the end, we deliberate over the detection technique for HPLC method development. A method for quantitative determination of an analyte in a complex matrix, The sample is injected on the column and separated chromatographically. Radial spacing (Rf) or linear velocity (Vall) of the eluted compounds are measured at each peak and analyzed for the concentration of the analyte.
