In ELISA the enzyme horseradish peroxidase HRP is bound to the region of the secondary antibody well of microtiter plate SARS CoV 2 antigen the tested sample

Why is it necessary to wash the samples repeatedly in ELISA To enhance the interaction between antibody and antigen To remove any proteins or antibodies which are unbound To increase samples concentration To make the sample clean Question 6 1 point Listen An antibody is Are also called immunoglobulins or lgs Made up of variable domains and a constant domain Composed of glycoproteins All of the above Y shaped in antigens
