The existence of multiple forms of avocado (Persea americana Mill. cv Hass) cellulase in crude protein extracts of ripe avocado fruit is reported. Cellulase was separated into at least 11 multiple forms by native isoelectric focusing in the pH range between 4 and 7 and visualized by both activity staining using Congo red and immunostaining. The enzyme components were acidic proteins with isoelectric points in the range of pH 5.10 to 6.80, the predominant forms having isoelectric points of 5.60, 5.80, 5.95, and 6.20. All 11 forms were immunologically related with molecular masses of 54 kilodaltons.
