Antibody 38C2 efficiently catalyzes deuterium-exchange reactions at the alpha position of a variety of ketones and aldehydes, including substrates that have a variety of sensitive functional groups. In addition to the regio- and chemoselectivity of these reactions, the catalytic rates (kcat) and rate-enhancement values (kcat/kun) are among the highest values ever observed with catalytic antibodies

Highly chemoselective conjugatereduction of α,β-unsaturated carbonyl compounds is now possible by using tributyl tin hydride with Pd(PØ3)4; an optimization study puts forth the importance of added radical scavenger and proton source in these reductions.
