Advantages and Disadvantages of Polyclonal and Monoclonal Antibodies Polyclonal antibodies Monoclonal antibodies Inexpensive to produce Expensive to produce Technology required is low High technology required Skills required are low  Training is required for the technology use Time scale is short ..

Lateral flow tests also known as Lateral Flow Immunochromatographic Assays are simple devices intended to detect the presence (or absence) of a target analyte in sample (matrix) without the need for specialized and costly equipment, though many lab based applications exist that are supported by reading equipment. Typically, these tests are used for medical diagnostics either for home testing, point of care testing, or laboratory use. A widely spread and well known application is the home pregnancy test. The technology is based on a series of capillary beds, such as pieces of porou..

The enzyme-linked immunosorbent assay (ELISA) is a test that uses antibodies and color change to identify a substance. ELISA is a popular format of a "wet-lab" type analytic biochemistry assay that uses a solid-phase enzyme immunoassay (EIA) to detect the presence of a substance, usually an antigen, in a liquid sample or wet sample. The ELISA has been used as a diagnostic tool in medicine and plant pathology, as well as a quality-control check in various industries. Antigens from the sample are attached to a surface. Then, a further specific antibody is applied over the surface so it ..
