M. Steinitz et al., SEPARATION OF RARE CELL SUBPOPULATIONS WITH THE AID OF BIOTIN-LABELEDLIGANDS, Medical oncology and tumor pharmacotherapy, 10(1-2), 1993, pp. 49-52
A universal method for selection of surface marker-positive cells is d
escribed. The cells, admixed with an excess of surface marker-negative
cells, are first labelled with a specific biotinylated ligand and the
n isolated with the aid of monoclonal, anti-biotin coated beads. The m
ethod enables selection and isolation of cells with a frequency as low
as 10(-4). The ligand can be an antigen (for selection of infrequent
antibody-producing cells), an antibody (for selection of surface antig
en-positive cells) or other molecules (for selection of specific recep
tor-positive cells).
