1. A method for monitoring biological media for protein fragments which comprises;
- contacting said biological media with a capture antibody;
said capture antibody being active against the sequences set forth in the Sequence Listing as SEQ ID NOS;
1 and 2; and
contacting said biological media with a detection antibody;
said capture antibody being active against the sequences set forth in the Sequence Listing as SEQ ID NOS;
3 and 4; and
detecting the amount of collagen fragments bound to said capture and detection antibodies;
orcontacting said biological media with a capture antibody;
said capture antibody being active against the sequences set forth in the Sequence Listing as SEQ ID NOS;
3 and 4; and
contacting said biological media with a detection antibody;
said detection antibody being active against the sequences set forth in the Sequence Listing as SEQ ID NOS;
1 and 2; and
detecting the amount of collagen fragments bound to said capture and detection antibodies.
