A hybridoma clone designated 6G5 has been selected by fusion of mouse
myeloma cell line Ag. 8653 with spleen cells from mice immunized with human
peripheral blood mononuclear cells (PBMC). The antibody produced by this clone
was found to be strongly reactive with four human B-cell lines in the conventional
immunological assays. Despite the fact that expression of most B cell-associated
markers are lost upon differentiation of B-cells to plasma cells, the expression of the
6G5 reactive molecule remains unchanged. The lack of reactivities of this MAb for
mature T-cells, and monocytic cell lines indicates that this MAb recognizes a B cell associated
marker. Western blot analysis indicated that the 6G5 MAb detected a
single band with molecular weight of 41 KDa from cell lysates of two human B-cell
lines, DAUDI and NALM6. Comparison of data obtained for 6G5 MAb with those
of the MAb known as OKTIO indicated that both MAbs may have reacted with the
same molecule.
