Complement factor H as a marker for detection of bladder cancer.

Background: The BTA TRAK and BTA stat tests for bladder cancer use monoclonal antibodies (mAbs) X13.2 and X52.1 to detect factor H (FH)-related material in urine.

Pig complement regulator factor H: molecular cloning and functional characterization.

Complement is an efficient defense mechanism of innate immunity. Factor H is the central complement regulator of the alternative pathway, acting in the fluid-phase and on self surfaces. Pigs are considered a suitable source for xenotransplantation and thus several membrane-bound pig complement regulators with importance for the acute rejection phase have been investigated.
