Table 2.

Decimal logarithmic values of binding constants (K, unit: L/mol) of 2′R-OTA-albumin complexes. LogK values were determined based on emission spectra of 2′R-OTA, recorded at 295 and 394 nm as excitation wavelengths.

Mycotoxin-Albumin Complex	logK (± SD) (λex = 295 nm, λem = 447 nm)	logK (±SD) (λex = 394 nm, λem = 447 nm)
2′R-OTA-HSA	6.28 ± 0.05	6.64 ± 0.10
2′R-OTA-BSA	6.67 ± 0.07	7.32 ± 0.06
2′R-OTA-PSA	6.21 ± 0.09	6.84 ± 0.12
2′R-OTA-RSA	6.45 ± 0.03	7.19 ± 0.21
