Hansen U, Tittor J, Gradmann D
J Membr Biol
. 2015 Feb;
75(2):141-69.
PMID: 25691374
The temporal behavior of current through a biological membrane can display more than one time constant. This study represents the reaction kinetic analysis of the nonsteady-state behavior of a class...

Planta
. 2013 Nov;
160(1):88-90.
PMID: 24258377
Studies using excised tissues usually suffer from a discrepancy in the results between freshly excised preparations and "aged" ones (i.e. preparations which are allowed to rest and-or regenerate for about...

Goldfarb V, Gradmann D
Plant Cell Rep
. 2013 Nov;
2(3):152-5.
PMID: 24257987
Partly purified membranes (with plasmalemma material) of Acetabularia mediterranea were studied with respect to ATPase activity in alkali- and Ca(++)-free media and its sensitivity to pH (5 - 9), oligomycin...

Behrens H, Gradmann D, Sievers A
Planta
. 2013 Nov;
163(4):463-72.
PMID: 24249445
Membrane potentials were measured in lateral statocytes of vertically and nonvertically growing roots of Lepidium sativum L. using conventional glass-microelectrode techniques. Statocytes in vertically growing roots showed a stable resting...
