English to Spanish Law/Patents Biology (-tech,-chem,micro-) patente química

=======================================
The antibodies tested were surmountable, those that could compete for binding with A-3, partially surmountable, those that could only partially compete for binding, and the unsurmountable antibodies, those that did not compete for binding with A-3
