write about one signal amplification strategy used in ELISA. ?
Homework Answers
ELISA also called enzyme linked immunosorbent assay is a widely used plate based assay technique that is used to detect peptides, hormones and proteins. It is an antigen antibody based reaction.One of the signal modification strategy that is used in ELISA technique is antigen antibody reaction. In this method specific antibody binds to target antigen. ELISA is normally performed in polystyrene well plates.On the basis by which it is performed ELISA is of two types direct and indirect ELISA.
In indirect ELISA technique antigen coated to a well is detected in two stages. In the first stage antibody specific to target antigen is provided which is then followed by the addition of enzyme labelled secondary antibody which will get bound to first added antibody.
Another commonly employed method is sandwich model.

ELISA Enzyme-Linked Immunosorbant Assay ELISA is a rapid test used for detecting or quantifying antibody (Ab) binding against viruses, bacteria and other materials or antigens (Ag). Can detect antibody antigen interaction. 96-well plates are made of polystyrene and are coated with either antigen or antibody. The function of the plate has to hold the immobilized either antigen or antibody. Legend for diagram below: Ag = antigen E = enzyme Substrate interacts with enzyme to allow colorimetric detection...
