Descrizione

Descrizione generale

B cells are lymphocytes that play a large role in the humoral immune response as opposed to the cell-mediated immune response that is governed by T cells. The principal function of B cells is to make antibodies against soluble antigens. B cells are an essential component of the adaptive immune system. FMC-7 B-Cell Lymphocyte Marker is a 105 kDa B cell restricted antigen which is expressed on about 50% of adult human peripheral blood B cells. Upon in vivo B cell activation FMC7 expression initially increases. B cells involved in antibody secretion have lost the FMC7 determinant. The monoclonal antibody FMC7 delineates a subpopulation of B lymphocytes in normal blood. Expression of the antigen recognized by FMC7 appears to be maturation-linked, and it serves to distinguish different types of B cell leukemia.

BIOCHEMISTRY: p I = 7.4

Specificità

The FMC-7 antibody was not clustered at the 5th Leucocyte Typing Workshop held in Boston USA 1993. This antibody detects a glycoprotein of 105kD found on circulating B-lymphocytes (Brooks et al., 1981). Studies on normal lymphocytes, leukaemic cells and cell lines indicate that FMC-7 is a marker for a limited segment of the B cell maturation pathway (Catovsky et al., 1981; Zola et al., 1984). This glycoprotein is expressed in varying degrees on normal circulating B-cells, chronic B-cell leukaemia (B-CLL), prolymphocytic leukaemia (PLL) and other B cell neoplasias (Zola et al., 1984, 1987; Bloem et al., 1988; Melo et al., 1988; Ferro & Zola, 1990; Mulligan, 1990; Zola et al., 1991; Burthem & Cawley, 1994; Huh et al., 1994). It labels the same population as CD22 antibodies but reacts with a different antigen (Zola et al. 1987).

Cell reactivity:1

Stains peripheral blood B lymphocytes and tonsil B lymphocytes. No reaction with granulocytes, monocytes, platelets, erythrocytes, T lymphocytes or null cells. Reacts with HRIK and Raji cell lines.
