Abstract:
A radiorespirometric method was developed for quantifying mineralization of [14C]-labeled substrates in deep-well microplates. Ninety-six 14CO2-traps were placed on an adhesive microplate sealing tape which made it possible to trap 14CO2 simultaneously from all wells. Trapped radioactivity was quantified by digital autoradiography.
