TABLE 1.

Kinetic and equilibrium constants of MAbs r667 and h667^a

Antibody	Cell origin	kon (M−1s−1)	koff (s−1)	KD (M)
h667	667 hybridoma	5.6 × 104	5.1 × 10−4	0.93 × 10−8
r667	Cos-7	4.2 × 104	14.2 × 10−4	3.4 × 10−8

^aKinetic constants were determined using the Biacore technology, as described in Materials and Methods, with Cos-7 and 667 hybridoma cell culture supernatants.
