KIDNEY ESTERASES OF THE MOUSE (MUS MUSCULUS): ELECTROPHORETIC ANALYSIS OF INBRED LINES C57BL/6J, RF/J AND SJL/J

Abstract

The water soluble esterases extracted from the kidney tissue of three inbred mouse strains (C57BL/6J, RF/J and SJL/J) are described. The analysis of the esterases was performed by means of starch gel electrophoresis. Between 25 and 30 esterase active sites (bands) were identified. A description and a classification are given for these esterases. Classification is based on relative electrophoretic mobilities and pharmacological properties of the esterases. Esterase polymorphisms are described between the three inbred strains studied. Esterase sexumal dimorphisms are also reported for these strains. Finally, information is given regarding the contribution (i.e., contamination) of serum esterases to the kidney esterase patterns.
