Immunoproteins Categories.

	Complement - A heat-sensitive complex system in fresh human and other sera which, in combination with antibodies, is important in the host defense mechanism against invading organisms. At least 20 distinct serum proteins operate within the complement system. (From McGraw-Hill Dictionary of Scientific Terms, 4th ed)
	Immunoglobulins - Glycoproteins present in the blood (ANTIBODIES) and in other tissue. They are classified by structure and activity into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M).
	Opsonins
	Properdin - Non-immunoglobulin gamma globulin component of the alternative complement pathway (COMPLEMENT PATHWAY, ALTERNATIVE). It complexes with C3b and stabilizes alternate pathway C3 convertase. (Dorland, 28th ed)
