Characteristic membrane transport parameters of boron clusters for selected analytes (cargos) in vesicles determined by Hill analysis

* Maximal activity; 10% error (SD), unless stated differently. ^† Effective concentration to reach 50% activity of Y_max; 10% error (SD), unless stated differently. ^‡ Activator efficiency; 10% error (SD, calculated by considering error propagation with respect to both, Y_max and EC₅₀). ^§ Transport efficiency; 5% error (SD, calculated by considering error propagation with respect to both, Y_max and EC₅₀), unless stated differently. ^ǁ Used as sodium salt. ^¶ Used as caesium salt. ^♯ n.a. = no detectable activity. ^☆ d.l. = dye leakage, no determination possible. ** n.t. = no detectable transport.
