Cloning of hybridomas by a single-cell transfer technique.

A method for cloning hybridomas is described which involves transfer of single cells with a capillary tubing connected to a suction apparatus. This method enables the efficient recovery of antibody-producing clones of differing abundances from the parent hybridoma cultures. The 4 cell lines submitted to this cloning procedure produced a 100% yield of positive wells upon recloning by the same method.
