Catalytic antibodies, including 38C2 and 33F12 are capable of efficiently , catalyzing a wide variety of ketone-ketone ketone-aldehyde, aldehyde-ketone, and aldehyde-aldehyde intermolecular aldol reactions and in some cases to , catalyze their subsequent dehydration to yield aldol condensation products. A number of intramolecular aldol reactions have also been defined. Catalysis of all intramolecular aldol reactions examined yields the corresponding condensation products.

Why it's free to use
- Filed December 18, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 18, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 18, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
