![]() ![]() The concentration of primary antibody present in the serum directly correlates with the intensity of the color. The substrate for enzyme is added to quantify the primary antibody through a color change. The solution is washed to remove unbound antibodies and then enzyme conjugated secondary antibodies are added. The primary antibody present in the sample bind specifically to the antigen after addition of sample. The antigen for which the sample must be analyzed is adhered to the wells of the microtiter plate. Indirect ELISAThe indirect ELISA detects the presence of antibody in a sample. Along with the enzyme- labelling of antigens or antibodies, the technique involves following three principles in combination which make it one of the most specific and sensitive than other immunoassays to detect the biological molecule: An immune reaction i. ![]() Principle of ELISAELISA is a plate- based assay technique. A number of enzymes have been employed for ELISA, including alkaline phosphatase, horseradish peroxidase, and B- galactosidase. An enzyme conjugated with an antibody reacts with a colorless substrate to generate a colored reaction product. It is also called solid- phase enzyme immunoassay as it employs an enzyme linked antigen or antibody as a marker for the detection of specific protein. ![]() Eero Aula: Tekniikan Englantia Englanti-Suomi sanasto Technical English.

Microfluidic cell culture has significant advantages over macroscopic culture, that is, culture in flasks, dishes and well-plates. Enzyme Linked Immunosorbent Assay (ELISA) is a very sensitive immunochemical technique which is used to access the presence of specific protein (antigen or antibody) in the given sample and it’s quantification.
