Molecular biology humor at its finest! This meme shows an antibody structure labeled "IDIOTYPE" but "WITHOUT THE Y,P,E" - leaving just "IDIOT." It's basically protein structure roasting you. The Y-shaped antibody molecule consists of heavy and light chains with variable regions that recognize antigens. Remove the Y (shape), P (protein), and E (epitope binding) and you're just left with... well, you get it. Savage immunological burn that would make even T-cells say "damn, that's cytotoxic."
