Currently, most assays for detection of biologically relevant binding events use radioactive or fluorescent dyes to tag one or more molecules. The need for multiple reagents limits label-based assay ...

This tutorial will give an overview of the principles of optical sensor-based label-free technology and how labeled and label-free technologies can be used together, helping researchers to: measure ...

Immunoassays are methods for detecting and quantifying analytes within a biological sample based on specific antigen-antibody reaction. They have been widely used in scientific research and ...

We have developed a rapid diffusion immunoassay that allows measurement of small molecules down to subnanomolar concentrations in <1 min. This competitive assay is based on measuring the distribution ...

Figure 1. Mechanism of biotin interference with immunoassay methodologies. Immunoassays in this case report contain a solid phase with a wash step that physically separates the label-bound ...

Following the first recorded immunoassays in the 1950s by Yalow and Berson, the industry has grown dramatically, reaching a net worth of $17 billion in 2012. These methods improve medical intervention ...

This article and associated images are based on a poster originally authored by Denise Sullivan, Zhong Yu, Benjamin Streeter, Stacie Chvatal and Daniel Millard and presented at ELRIG Drug Discovery ...
