title: A capillary technique for cloning Amoeba from single cells.
abstract: Each amoeba is placed in a drop of approximately 40 microliter of a balanced 'medium + food' solution introduced into the central region of a 7 cm long capillary tube which has first been fused at one end. Such amoebae divide to form clones of 20-30 cells without changing capillaries, though additional food may be required after 7-10 days. Experiments on damage induced by chemicals, cell cycle sensitivities and nuclear/cytoplasmic inheritance, which may involve the cloning of some 2-3,000 or more cells can be carried out with comparative ease. Apart from research, the capillary cloning technique has proved useful in the teaching laboratory. It is adaptable, and can be used for Protozoa other than amoebae, even for requiring sterile conditions.
