Which antibodies are enhanced by enzymes (papain, bromelin, ficin, trypsin)?

Enzymes such as papain, bromelain, ficin, and trypsin modify the red cell surface by proteolysis, altering antigen expression. This often makes certain antibody–antigen reactions stronger because the enzyme treatment exposes or preserves epitopes that these antibodies recognize. In practice, antibodies against Rh group antigens (like D, C, E) and the Kidd antigens (Jka, Jkb) commonly show enhanced agglutination after enzyme-treated cells. Anti-I and anti-P1 can also be more reactive in some situations with enzyme-treated cells. On the other hand, many other antigens are destroyed by these enzymes, including Kell antigens, so anti-K often shows reduced or absent reactivity after enzyme treatment. So, antibodies that are enhanced by enzyme treatment are typically those in the Rh and Kidd systems (and sometimes I and P1), whereas Kell is not enhanced.
