However, they did not bind to either free cTnI or when cTnI was associated with C (the I-C binary complex).
The proposed method is based on a binary complex formation between the studied drugs and eosin Y.
IGF-I treatment increases the binary complex of IGF-I and IGFBP-3, but only GH treatment induces the formation of both the binary and ternary complexes (Gargosky et al., 1994).

[2] Amongst experimental evidence that the interactions give rise to the formation of a binary complex (Figure 1a) are solid-liquid phase diagrams, [3,4] and indications in 1H-NMR or IR spectra of the existence of hydrogen bonds.
Intrinsic protein fluorescence quenching studies demonstrated that both inhibitors bound to the free enzyme and to the E-NADP+ binary complex. The dissociation constants determined from these experiments were similar to the inhibition constants.
These reactions include the formation of a binary complex between the metal and mono-deprotonated ascorbic acid molecule, and dioxygen coordination by the bound metal.
The structure of the binary complex of the enzyme and glutathione indicates that the hydroxyl group of Tyr6 is located between 3.2 A and 3.5 A from the sulfur of glutathione, well within hydrogen bonding distance.
Data indicate that cTnI circulates mainly as a binary complex with cTnC in the blood of patients with acute MI, but it also circulates as free cTnI and as a ternary complex, cTnICT.
The titration of up to 800 [micro]g/L cTnT into the cardiac troponin IC binary complex (cTnIC) gave recoveries of 96% in LiHep plasma and 97% in serum.
The predominant form of cTnI in acute myocardial infarction (AMI) patients is the binary complex IC (8,11).
