Clone: MT1
Background: CD43 antigen is expressed on all T cells, NK cells, myeloid cells and monocytes as well as on CD5 positive mature B cells. It is also present on all immature hematopoietic cells in the bone marrow. The antigen is deficient in patients with Wiskott-Aldrich syndrome. A soluble form of CD43 is present in Human Serum.
Source: MT1 is a monoclonal antibody derived by fusion of X63 Mouse myeloma cells with spleen cells from of Balb/c mice, intraperitoneally immunized with Human monocytes isolated by centrifugal elutriation. Immunizations were carried out at least twice at 2-week intervals with: A) cell suspensions of a lymph node involved by Hodgkin's disease; B) cell suspensions of a lymph node involved by Bchronic lymphatic leukemia; C) cells of Hodgkin's cell line DEV, respectively. No adjuvants were used (3).
Specificity: Clone MT1 produces Mouse IgG1 immunoglobulins reactive with a 95-115 kD highly sialated glycoprotein. This antibody is used to identify B cell lines and myeloma cells. It may be used in the diagnosis of chronic lymphocytic leukemias (CLL), as an alternative to CD5. The antigen detected by MT1 is the only marker expressed on neoplasms of the very early precursor cells. In immunohistochemistry it reacts with T cells, macrophages, myeloid cells and B cells (weak). It is used for the typing of lymphomas in paraffin sections. CD43 may function as an adhesion molecule via interaction with CD54 although this has not been definitely established. It may also inhibit leucocyte interactions with other cells. The antigen is involved in the activation of T-cells, B cells, NK cells and monocytes. The membrane proximal portion of the cytoplasmic domain mediates an association with the cytoskeleton.
Formulation: Each vial contains 100 ul 1 mg/ml purified monoclonal antibody in PBS containing 0.09% sodium azide.
