Abstract
Liver acid phosphatases were separated electrophoretically using liver extracts of a White Leghorn strain and boric acid-Tris buffers of different pH. The electrophoretic patterns of the acid phos-phatase showed 2 distinct regions of activities which were designated as I and II, in order of their proximity to the anodic end of the gel. Three distinctive acid phosphatase phenotypes were found in Region II, and the best resolution of the phenotypes was obtained when they were subjected to electrophoresis at pH 7.6. These phenotypes were controlled by a pair of autosomal codominant alleles: Acp-2A producing a fast moving band and Acp-2B producing a slow band.
