1. A method of detecting binding of a binding partner to a phage comprising:
- (a) immobilizing a crude phage preparation, unconcentrated phage preparation, non-homogenous phage preparation, concentrated phage preparation or a combination thereof on a biosensor;
(b) contacting the biosensor with the binding partner;
(c) detecting binding of the binding partner to the phage immobilized on the biosensor.

12. A method for determining epitope classes of antibodies in an antibody population comprising:
-
(a) immobilizing a display phage, antibody, or antibody fragment to a biosensor;
(b) contacting the biosensor with a binding partner that specifically binds to the display phage, antibody, or antibody fragment immobilized to the biosensor, under conditions suitable for binding of the binding partner to the display phage, antibody, or antibody fragment;
(c) contacting the antibody population with the biosensor;
wherein, a detectable signal generated by binding of the antibody population to the binding partner indicates that different epitope classes are present in the antibody population than in the immobilized display phage, antibody, or antibody fragment. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
