CDw75 [LN-1]

Cdw75 is proposed as the ligand for CD22 mediating B-cell-B-cell interaction. Clone LN1 recognizes a sialoantigen on cell membranes. On tissue sections, it causes a marked reaction with the B lymphocytes in germinal centers, but only a faint reaction with B lymphocytes of the mantle zone in lymphatic tissues. LN1 also reacts with various types of epithelial cells, including cells of the distal renal tubules, breast, bronchus, prostate and erythrocytes.
