Kinetics and thermodynamics of binding of sLex and Lex conjugates to scFvs

scFv sLex-biotin

kon (×104 M−1 s−1) koff (×10−3 s−1) Kd (×10−7 M) kon (×104 M−1 s−1) koff (×10−3 s−1) Kd (×10−7 M)
S6 4.3 4.7 1.1 1.3 8.3 6.2
S7 1.1 5.3 4.9 2.6 7.3 2.9
S8 5.1 9.1 1.8 2.3 6.5 2.9
S10 1.2 6.7 5.7 2.1 4.6 2.2

The kinetic constants of scFvs were measured using the BIAcore biosensor: kon, association rate constant; koff, dissociation rate constant; Kd, calculated (Kd = koff/kon).
