Listed below are antibodies that target CD55 molecule, decay accelerating factor for complement, a protein known to be expressed in mice. Its ortholog in humans is CD55 molecule (Cromer blood group), encoded by the CD55 gene. CD55 is a member of the Receptors of complement activation (RCA) protein family and is known to recognize C4b and C3b fragments that condense with cell-surface hydroxyl or amino groups when nascent C4b and C3b are locally generated during C4 and c3 activation.
