English term

quench/quenching

English to Spanish Science Biology (-tech,-chem,micro-)
Pilot experiments demon strated that 1 unit of the antiFITC antibody would quench 90 of the fluorescence associated with 10 fil of a 2.5 mg ml FITCdextran

Incubate cells with or without quenching antibody for 0, 5, 10, 20 min. for 0min incubation, quenching antibody is not required

GRACIAS:)

extinguir, amortiguar [la fluorescencia] / extinción, amortiguación [de la fluorescencia]

Personalmente, prefiero “extinguir” y sus derivados, pero en este contexto también son fecuentes “amortiguar” y sus derivados. A veces se encuentra también “desactivar” y “desactivación”.

Tres ejemplos con “extinguir” o un derivado):
