fab fragments were found to dissociate with a half-time value of about 16 h , whereas the homogeneous binding of tnp-antibody dissociated with a half-time of less than 4 h , indicating that both the bivalence of antibodies and the solid phase contributed to the stability of surface-bound antigen-antibody complexes .
