[Human chromosome banding with raw extract of fruits or leaves of papaya].
One week old human chromosome preparations were treated with filtrate from one liquefied leaf (53 g) of papaya (Carica papaya) in 100 ml of distilled water, and stained with 1.5% Giemsa (pH 6.8). Good chromosome banding was obtained after 2 min of treatment. Solutions that have been frozen even for years are effective and the method is cheaper and easier than others.
