Please arrange the following steps about ELIZA (Enzyme-linked immunosorbent assay) in chronological order

i. incubate with antibody-enzyme complex that binds primary antibody

ii. coat surface with antigen, block unoccupied sites with nonspecific protein

iii. add substrate, formation of colored product indicates presence of specific antigen

iv. incubate with primary antibody against specific antigen
