The method allows the detection and quantification of glycosyltransferase activity using an ELISA-based procedure and carbohydrate-specific monoclonal antibodies. Avoids the use of radiolabeled substrates. Bruce A.

Assays for B Lymphocyte Function Protocols- https://catalog.invitrogen.com/index.cfm?fuseaction=iProtocol.unitSectionTree&treeNodeID=9E66340AD6485AA0FEB8F538B2FD389E&objectid=6674A538AC9B642C5CD51556EF7B3D26
Describes the antigenic stimulation of in vitro antibody production by B cells and the subsequent measurement of secreted antibodies. The first protocol is a generalized system for inducing in vitro antibody production and can accommodate various types of antigens under study. Secreted antibodies can then be measured with an enzyme-linked immunosorbent assay (ELISA) or other soluble-antibody detection systems. - [Read Assays for B Lymphocyte Function Protocols]
Cytokine sandwich ELISA are sensitive enzyme immunoassays that can specifically detect and quantitate the concentration of soluble cytokine and chemokine proteins. BD Biosciences - [Read Cytokine ELISA Protocol]
Qualitative ELISA (Enzyme-Linked Immunosorbent Assay) used for screening detection of anti-platelet antibodies or for detection of platelet-associated Ig (PAIg). Andrei Musaji Viral immunity and pathogenesis group, Universite Catholique de Louvain. - [Read ELISA for detection of platelet-associated Ig (PAIg)]
The cyclooxygenase (COX) reaction can be monitored by measurement of oxygen consumption, peroxidase co-substrate oxidation or prostaglandin (PG) detection. This protocol describes a procedure measuring cyclooxygenase activity by quantifying PGE2 produced by enzymatic conversion of arachidonic acid, in the presence or absence of potential inhibitors. - [Read ELISA Method to Measure Inhibition of the COX Enzymes Protocol]
