Sensitize a 96-well microtiter plate with purified antigen. Prepare a solution of the purified antigen of interest in phosphate buffer (see recipe below) such that a concentration of approximately 1 ...

Immunoassays are a powerful technique for detecting and measuring antigens and antibodies. Immunoassays can be classified three ways based on the steps involved: antibody capture antigen capture two ...

OUTLINEThis modification of qualitative ELISA (Enzyme-Linked Immunosorbent Assay) is used for either screening detection of anti-platelet antibodies or for detection of platelet-associated Ig (PAIg) ( ...

This protocol can be used for detection of gangliosides.Spicific antibodies to gangliosides are added to cells and allowed to bind to the cell surface. The nonbound antibody is washed away and an enzy ...
