1 Fibronectin binds to complement-coated agarose beads and increases their association to mouse macrophages. Sepharose fibronectin 1 Mus musculus
2 We have studied the binding of fibronectin to complement (C3b, C3bi, C3d)-coated agarose beads and its effect on cell association of such beads to mouse macrophages. Sepharose fibronectin 1 Mus musculus
3 Fibronectin bound to agarose beads preincubated in human serum, whereas no binding occurred after preincubation of the beads with complement-inactivated (50 degrees C for 20 min or ethylenediaminetetraacetic acid) sera. Sepharose fibronectin 1 Mus musculus
4 A similar amount of fibronectin bound to agarose beads coated with equimolar amounts of C3b, C3bi, or C3d, suggesting that the common domain C3d carries the main binding site(s) for fibronectin. Sepharose fibronectin 1 Mus musculus
5 Preincubation of serum-treated and trypsinized agarose beads with fibronectin led to an increased association (22%) of such beads to mouse macrophages. Sepharose fibronectin 1 Mus musculus
6 The results indicate that fibronectin promotes binding of complement-coated agarose beads to mouse macrophages, whereas the ingestion of the beads is mediated via complement C3 receptors. Sepharose fibronectin 1 Mus musculus
