ABSTRACT:
The invention relates to methods of agglutinating or capturing cells comprising providing a mixture comprising a population of cells and a population of bacteriophage expressing a first antibody on the surface of the bacteriophage, the first antibody being specific for an antigen-bearing moiety expressed by at least a portion of the cells in the cell population, wherein the first antibody binds to the portion of the cells causing the bacteriophage to also bind to the portion of the cells, adding to the mixture a second antibody specific for the bacteriophage, wherein binding of the second antibody to bacteriophage bound to the portion of the cells causes the portion of the cells to agglutinate or be captured.
