Interaction of C1q with beta 2-microglobulin.
Beta 2-microglobulin aggregated with glutaric dialdehyde was efficiently bound to C1q in fluid and solid phase assay systems. Furthermore, affinity chromatography experiments suggested reactivity of monomeric beta 2-microglobulin with C1q. In spite of its C1q binding capacity, the aggregated beta 2-microglobulin did not activate the C1 complex in serum. This however, might have been due to the mode of aggregation.
