Monoclonal antibodies, compositions and methods for detecting complement factor d

Abstract

Disclosed herein are monoclonal antibodies that specifically bind to human mature Factor D and that do not bind to human Pro-Factor D, monoclonal antibodies that specifically bind to human Pro-Factor D and do not bind to human mature Factor D, and monoclonal antibodies that bind to both human mature Factor D and human Pro-Factor D. Also disclosed are methods of using the monoclonal antibodies, and compositions comprising the same, for detection of the mature and / or the pro-form of Factor D in biological samples, to determine the status of the Alternative Pathway of Complement (APC ) in a mammalian subject, or to determine the status of Factor D after treatment with a MASP-3 inhibitory agent which inhibits the conversion of Pro-Factor D to mature Factor D.
