Method |
"The reactions take place in an
airtight 3-ml glass water-jacketed and stirred chamber connected
to the ion source of a mass spectrometer through a thin
0.012-mm-thick Teflon membrane supported by a sintered
glass disc, through which gases are dissolved in the solution
diffuse. The chamber has a glass pH electrode and a removable
stopper for the addition of reactants." |
Comments |
"DIDS (100µM) did not alter the calculated CA [carbonic anhydrase]
activity in the intact red cells, but did lower Pm,HCO3-
to about
half. The interesting finding is that membrane CO2 permeability,
from a value of 1cm/sec or higher in the control
experiments, was lowered by the drug to a value of 0.1cm/sec." |
