anti-LRP, 85kD, CD91, 5A6, purified IgG1

5A6 specifically reacts with the 85 kD b-chain of human LRP/a2MR which is expressed in a restricted spectrum of cell types (for a recent review cf. Herz & Strickland). A strong immunohistochemical reaction is seen in hepatocytes, tissue macrophages, subsets of neurones and astrocytes in the central nervous system, fibroblasts, smooth muscle cells, and monocyte-derived foam cells in atherosclerotic lesions in the arterial wall. The antibody can also be used for the characterization of a subset of myelo-monocytic subtypes of chronic and acute leukemia (CD 91). Neutralizing effects of 5A6 have also been reported (Basu et al., 2001).
