As a senior technician within this company, you will work in a department that is specialized in ELISA method development. Here, you will first and foremost be responsible for developing methods to analyze a great variety of samples using ELISA. Besides that, you will also be the point of The ELISA pictured in Figure 1 is what is known as a sandwich ELISA, here two sets of antibodies are used to detect secreted products, e.g. cytokines. The method is stepwise in the order shown. The 1st step is to coat the ELISA plate with capture antibody , any excess, unbound antibody is then washed from the plate. Further considerations for development included binding protein interference and limited sample volume.

In this thesis, we build on the proximity ligation assay to develop and apply which was considerably below the detection threshold for ELISA.

ELISA development involves choosing a format, gathering the needed components, and constructing a working protocol. ELISA optimization involves

ELISA stands for enzyme-linked immunosorbent assay, which refers to the fact that antibodies coupled to enzymes are used to Enzyme-linked immunosorbent assay (ELISA) is a method of target antigen (or antibody) capture in samples using a specific antibody (or antigen), and of target molecule detection/quantitation using an enzyme reaction with its substrate.
