A Western Blot Differs from a Recombinant Immunoblot Because

A western blot differs from a recombinant immunoblot because

A) the antigens on the nitrocellulose strip in the western blot have been blotted directly onto the blot but the antigens on the recombinant immunoblot are electrophoresed onto the blot
B) because the antigens on the nitrocellulose strip in the western blot have been electrophoresed and then blotted onto the blot and the recombinant immunoblot the antigens are just pipetted onto the blot
C) because in a western a direct EIA is performed and in a recombinant immunoblot an indirect EIA is performed
D) because in a western an indirect EIA is performed and in a recombinant immunoblot an indirect EIA is performed
