Table 2.

Bound equivalents of the Rh and Ru compounds per HSA calculated on the basis of CZE measurements at HSA-to-compound ratios of 1: > 20

HSA-to-compound ratio	1: > 20^a
Bound form	Complex	Metal ion	Σ
RhCp*	–	24 ± 3^b	–
dhp complex	0	8 ± 1	8 ± 1
pic complex	nm^c	nm^c	12 ± 1
RuCym	–	14 ± 1^b	–
dhp complex	5 ± 0.7	4 ± 0.4	8 ± 0.6
pic complex	nm^c	nm^c	4 ± 0.6

For metal complexes bound forms of the original complex (complex) and of the organometallic cation (metal ion) and their sum (Σ) are listed as well [25 °C, pH 7.40 (PBS′)]

^aCalculated values are based on at least four measurements

^bCalculated on basis of ultrafiltration measurements, see details in the Experimental Section

^cNot measurable. Ligand pic binds on HSA as well, therefore values of bound complex and metal ion cannot be estimated, only the sum of them
