Bioanalytical Assay Development and Validation

ELISA is a widely utilized immunoassay for quantitating and detecting proteins, hormones, peptides, cytokines, antibodies, and other drugs along with their metabolites. ELISA methods are effective in quantitatively detecting any molecule or antigen that can be ascertained by an antibody. For example, ELISA methods are used in pregnancy testing, infectious disease identification, and detection of cytokines, and soluble receptor proteins, etc. Due to the precision, sensitivity, assay speed, and ease of quantitation, ELISA method development is a common choice for several diagnostic and research applications.

ELISA method is a widely utilized immunoassay for quantitating and detecting proteins, hormones, peptides, cytokines, antibodies, and other drugs along with their metabolites. ELISA methods are effective in quantitatively detecting any molecule, or antigen, that can be ascertained by an antibody. ELISA method is one of the most widely used immunoassay formats. The elisa method involves immobilizing the capture antibody, capturing the antigen of interest onto it and then following it up with a detection antibody that binds to a different region (epitopes) on this captured molecule.

An ELISA is a simple, yet very reliable and cost-effective method for detecting and quantitating the presence of an analyte in a sample. In a sandwich ELISA, the protein you are interested in detecting is bound by two antibodies that bind to epitopes on opposite ends of the antigen. This sandwich forms at the bottom of a microplate well with your antibody solution (detection antibody) located above it and your sample located below it. After an incubation period, your detection antibody will become bound to any antigen present in your sample. Once bound, your detection antibody can be quantitated using our proprietary lipid dye conjugated secondary antibody.

Bioanalytical assay development is the process of determining the design implications, limitations, favorable conditions, and suitability of a drug for the intended treatment. Before assay development can be initiated, it’s recommended to understand the physiochemical properties of the analyte. Bioanalytical assays play a crucial role in the discovery and development of pharmaceutical products given their ability to discern purity, identity, performance, and potency of these compounds. Furthermore, bioscience tools allow reproducible and reliable quantitation of analytes in various biological matrices such as plasma or serum.

Bioanalytical assay development helps determine the design implications, limitations, favorable conditions, and suitability of a drug for the intended treatment. Before assay development and validation can be initiated, it is recommended to understand the physiochemical properties of the analyte. Bioanalytical assay development is considerably informed by the details on protein binding and in vivo/in vitro metabolism along with essential aspects of prior work on the method.

Before assay development, it is recommended to understand the physiochemical properties of the analyte. Bioanalytical assays play a crucial role in discovering and developing pharmaceutical products given their ability to discern purity, identity, performance and potency of these compounds. To start the process off we need to understand some basic aspects of protein binding, in vivo/in vitro metabolism along with essential details such as previous work on the method.
