Target Details

  • Target: Complement receptor 1 (CR1, CD35)
  • Molecular weight: 130 kDa
  • Target background: CR1 is found on many leucocytes and binds C3b and C4b. E11 detects CR1 on most leukemic monoblasts, granulocytes and may be used to define B cell lymphomas. E11 binds to a 222kDa antigen. This antibody is specific for a binding site in CR1 which is distal from the C3b binding site. As such CR1 activity is not blocked. CR1 is a cell membrane-bound, monomeric glycoprotein and its primary function is to serve as the cellular receptor for C3b and C4b within the complement system. CR1 is present on neutrophils, eosinophils, monocytes, B-cells, some NK-cells, erythrocytes, myeloid leukaemia's, follicular dendritic reticulum cells and is negative on basophils. Anti-CR1 E11 is useful for identifying CR1 on various cells in tissue sections, and for quantitating CR1 on erythrocytes and neutrophils.
